I have a custom FuelTank object, anylogic tank but with some extra logic. It has a parameter SimTank of type "storageTank". The anylogic "tank" block (inside the FuelTank object) has its "StorageTank" set to this parameter.
I now have a TankFarm object which in turn incorporates a number of these FuelTank objects. And a Collection - FuelTanks to reference each of the tanks. It has a parameter SimTanks, which is a one-dimensional array of type Other, storageTank[].
So now.
If I configure the TankFarm object, select each tank in the object and one by one set each tank's SimTank parameter to "SimTanks[0]", "SimTanks[1]", etc. then populate SimTanks with the list of storageTanks I want to use in my visual representation, everything works fine. EXCEPT if I have less "storageTanks" in my SimTanks array than there are tanks in my TankFarm object. (which is understandable. If I only have 4 storageTanks, but 5 tanks in my tankfarm, then tank 5 will have its "SimTank" parameter set to "SimTanks[4]" which of course does not exist in the "SimTanks" array and correspondingly gives an error)
To get around this problem, I use a function and run it when the simulation starts:
for (int s=0; s<=(TankFarm.SimTanks.length-1); s++)
TankFarm.FuelTanks.get(s).SimTank = SimTanks[s];
So now if the user only added 4 "storageTank objects" to his visual simulation, only the first four tanks in the "TankFarm" are assigned a storageTank the last one is "null".
Code works (does not give an error), but when you run the model there is ZERO simulation, none, nothing happens with the StorageTank objects in the visual representation, they don't show anything; it is as if the AnyLogic tanks (inside the individual FuelTank objects), are not linked with the StorageTanks?
How do I fix this please"? How do I dynamically assign the StorageTank objects dropped on the main window and added to the SimTanks array to the tanks in my FuelTank object?
(To clarify, if I do it manually, one by one, it works - but then if I have less storageTanks than Tanks in my farm it gives an error. If I do exactly the same dynamically, through code, it does not give an error, but the simulation does not work, the storageTanks does not show anything??)
This issue has been resolved thank you. I created a function inside the library object that returns a StorageTank. Then added a parameter that the user configures to use the object's animation or add "his own" animation. Each tank object in the library then calls the function which returns a StorageTank object - either the built-in object (built into the library object) or the one the user added manually. The method works perfectly - user may drop the library object (which includes its own animation) but then configure it to not use that animation, in which case user has to build and assign his own animation.

I would like to modify an Xcos block from within a gateway function using the new (non-legacy) Scilab API, for example, replace the block's model property by a new model structure. In other words, do the same as the Scilab command(s):
m = scicos_model()
block.model = m
However, I did not manage to achieve this behavior with the functions from Scilab 6 API: a block created by standard_define() is correctly passed to my gateway function, where this argument is available as scilabVar of type 128. On the other hand, the Scilab help claims that a block is a "scilab tlist of type "Block" with fields : graphics, model, gui and doc".
Attempts
Assume scilabVar block taken from gateway function argument, string constants of type wchar_t[], scilabVar model holding the result of scicos_model():
Application of function scilab_setTListField (env, block, "model", model) returns error status (as its equivalents for MList and List do)
Knowing that property .model is at index 3, a setfield (3, model, block) called through scilab_call ("setfield", ...) also fails.
This is not surprising: when called directly from the Scilab command line, it ends up with
setfield: Wrong type for input argument #3: List expected. .
However, a getfield (3, block) works, so that at least read access to the block's data fields is possible.
An external helper function
function block = blockSetModel (block, model)
block.model = model
endfunction
also called through scilab_call("blockSetModel", ...) actually returns a block with changed model,
but the original block passed to this function remains unchanged.
Although ugly, this gives at least a way to construct an individual block structure
which needs to be returned as a copy.
Summary
So, is there simply a function missing in the API, which returns the TList (or whatever) behind a type 128 pointer variable?
Or is there any other approach to this problem I was unable to discover?
Background
The goal behind is to move the block definition task from the usual interfacing "gui" function (e.g. a Scilab script MyBlock.sci) into own C code. For this purpose, the interfacing function is reduced to a wrapper around a C gateway, which, for example, usesscilab_call ("standard_define",...) to create a new block when being called with parameter job=="define".
Modification of the contained model and graphics objects through the Scilab API works fine since these are standard list types. However, getting or setting these objects as attributes .model and .graphics of the
original block fails as described above.
Starting from Scilab/Xcos 6.0.0, the data-structure behind a block is no more an MList (or TList) so you cannot upgrade the model to your own MList. All the data behind are stored using a classical MVC within a C++ coded Block.hxx.
On each try you made, a serialization/deserialization happens to reconstruct the block model field as a Scilab value.
Could you describe what kind of field you want to append/edit regarding the block structure ? Some of the predefined fields might be enough to pass extra information.
In my current project in Access VBA, I created a window which works like a console and now I am trying to add a possibility to display any public variable. It should work like:
Show_var [variable_name]
So it should be like in the direct window where i can type:
? pVar.variable_A
I found out that using
Application.VBE.ActiveVBProject.VBComponents(11).CodeModule.CountOfLines
I can display the number of lines within a module or form so I thought perhaps I could somehow find the variables there, cycle through them and when the correct one is found, its value can be shown. OFC I could make a Select Case Statement where all variables are included but that is not the way I want to do it because it is complicated and must be changed every time update my public variable list.
There are so many problems that I think you are out of luck. Let me just list some of them:
There is no way to get a list of all variables - that would mean you would need access to the internal symbol table.
As a consequence, you would have to read the code (CodeModule lets you read the code of a module), and write an own parser to fetch all declarations (hopefully you use Option Explicit)
AFAIK, the is no method that can access the content of a variable via it's name.
Even if there would be any such method: What would you do with different data types, arrays and especially with objects.
If a user runs into problems, often it is a runtime error. If you don't handle that errors with some kind of error handler, the only option if a user cannot enter the debugger is to press "End" - which would destroy the content of all variables.
You have to deal with scope of variables, you can have several variables with the same name and you will likely have lots of variables that are out of scope in the moment you want to dump them.
I am trying to assign the value of this stucture path to a fieldsymbol, but this path does not work because it has a table in it's path.
But with in the debugger this value of this path is shown correctly.
Is there a way to dynamically assign a component of a table line to a fieldsymbol, by passing one path?
If not then I will just read the table line and then use the path to get the wanted value.
ls_struct (Struct)
- SUPPLYCHAINTRADETRANSACTION (Struct)
- INCL_SUPP_CHAIN_ITEM (Table)
- ASSOCIATEDDOCUMENTLINEDOCUMENT (Element)
i_component_path = |IG_DDIC-SUPPLYCHAINTRADETRANSACTION-INCL_SUPP_CHAIN_ITEM[1]-ASSOCIATEDDOCUMENTLINEDOCUMENT|.
ASSIGN (i_component_path) TO FIELD-SYMBOL(<lg_value>).
IF <lg_value> IS NOT ASSIGNED.
return.
ENDIF.
<lg_value> won't be assigned
Solution by Sandra Rossi
The debugger has its own syntax and own logic, it doesn't apply the ASSIGN algorithm at all. With ABAP source code, you have to use ASSIGN twice, the first one to reach the internal table, then you select the first line, and the second one to reach the component of the line.
The debugger works completely differently, the debugger code works only in debug mode, you can't call the code from the debugger (i.e. if you call it, the kernel code used by the debugger will fail). No, there's no "abappath". There are the XSL transformation objects (xpath), but it's slow for what you ask.
Thank you very much
This seems to be a rather unexpected limitation of the ASSIGN statement. Probably worth a ticket to SAP's ABAP language group to clarify whether it's even a bug.
While this works:
ASSIGN data-some_table[ 1 ]-some_field TO FIELD-SYMBOL(<lv_source>).
the same expressed as a string doesn't:
ASSIGN (`data-some_table[ 1 ]-some_field`) TO FIELD-SYMBOL(<lv_source>).
Alternative 1 for (name) of the ABAP keyword documentation for the ASSIGN statement says that "[t]he name in name is structured in the same way as if specified directly".
However, this declaration is immediately followed by "the content of name must be the name of a data object which may contain offsets and lengths, structure component selectors, and component selectors for assigning structured data objects and attributes in classes or objects", a list that does not include the table expressions we would need here.
How can i retrieve the is_sfparam-content, either using query or function module.
then will be passed as a parameter to cl_recp_data_cn_general=>get_contract.
do you have any idea? Where can I get that is_sfparam-content?
Thanks
CALL METHOD cl_recp_data_cn_general=>get_contract
EXPORTING
id_guid = is_sfparam-content
IMPORTING
es_contract = contract
CHANGING
cf_error = lf_error.
This guid paramater brings no sense as it is generated in runtime. You can check this yourself by putting breakpoint at the first line (e.g. line 102) of method cl_recp_data_cn_general=>get_contract and checking id_guid var in debugger. It will be different with each run of preview in RECN tcode.
Check also line 11 of CONSTRUCTOR method of CL_RECP_SF_DOC class, it is executed during each form generation.
The real contract object lays in variable go_busobj of program SAPLRECA_BDT_APPL_TOOL which brings RECN functionality and it is global i.e. it is loaded into memory constantly while RECN is running, just passing doc object into called methods thru the call stack, which you can follow in debugger.
Where really form generation takes place is CL_RECP_SF_JOB class, for preview it is _FP_PREVIEW method, for print it is _FP_PRINT. For example, in preview method form FM is called in that place
What you need to do if you want to call arbitrary contract print-form, which is what I assume you want to do by asking this question:
Find out smartform FM name by putting breakpoint in the above line
Build parameters for this FM calling. The only obligatory parameter is LS_SFPARAM-CONTENT which is the GUID.
You can generate this GUID manually by creating CL_RECP_SF_DOC object, let it be io_doc var. The constructor of this object has input parameter is_doc which should be filled according to the attributes of contract which you want to print, and which are stored in VIBDRO and VICNCN tables.
After creating this object pass its attribute io_doc->md_guid to ls_sfparam-content, generate other parameters with CL_RECP_SF_JOB->_sf_get_form_param and
Run the smartform FM /1BCDWB/SF000000XX found at step 1 with these parameters
I didn't check all these steps by myself but I believe it should work.
I am trying to populate the infoobject 0LOGSYS in a DSO when a load from a datasource occurs. The idea being that you could tell what sourcesystem the data was loaded from that is needed for a certain requirement. As of now I have a routine set up on a transformation rule for 0LOGSYS. No syntax errors, everything runs during the load, but no data is populated. Tried to debug but for some reason my BREAKPOINT is not getting picked up.
Here is the code that I have placed in the routine. Also, I am trying to do this without assigning any source field so maybe that is causing an issue. Not sure though.
TYPE-POOLS: RSSM.
Data: G_S_MINFO TYPE RSSM_S_MINFO.
CALL FUNCTION 'RSDG_ID_GET_FROM_LOGSYS'
EXPORTING
i_source_system = G_S_MINFO-LOGSYS
IMPORTING
e_soursysid = RESULT
EXCEPTIONS
id_not_found = 1.
Solved this a different way. There are runtime attributes that can be pulled from any request via the methods of "if_rsbk_request_admintab_view" which is instanciated automatically at the beginning of each transformation routine. Here is the code that I put in the routine.
*declaring a local variable like the result type LOGSYS
Data: lvSource like RESULT.
*runs a method to get the source system from the runtime attributes of
*the request
*"p_r_request" is an instance of "if_rsbk_request_admintab_view" which
*has many different methods for runtime attributes
lvSource = p_r_request->GET_LOGSYS( ).
RESULT = lvSource.
If this is the complete source code, it's not surprising that nothing is returned. You declare a new structured variable named G_S_MINFO, don't assign any value to it and return its contents. Unless you deleted the steps from your code sample that are supposed to fill the variable with values, it would be a grave bug if anything else than an initial value was returned.
EDIT: Even with the updated code, I still doubt this will work. Now you pass G_S_MINFO-LOGSYS to a function module that supposedly looks up some system ID without initializing it. Garbage in, garbage out. Or in this case, initial value in, initial value out.
