I'm trying to save an Object on form.values to work with it later on a Query.
The problem is, even I have used it on another project, this time it gives this error:
Does anyone have some clue about this?
The specific line I'm inputting this is this one:
onChange={form.handleChange('MultipleSelect')({})}
I'm not sure, but I think it is not finding the '_eventOrTextValue' function...
I have tried passing integers, objects, arrays, but the only kind of value it accepts is string...
Oddly I used this same mirrored function on another project the same way...

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 use the Accord.net library to build test method of several of the machine learning algorithms that library supports.
One of the issues I have run into is that when I am trying to codify my string data, the Codification class does not seem capable of dealing with any datatable columns that are not strings, despite the documentation saying otherwise.
Codification codebook = new Codification(fulldata, AllAttributeNames);
I call that line where fulldata is a datatable, and I have tried including columns of both Int32 type and Double type, and the Codification class has thrown an error saying it is unable to convert them to type String.
"System.InvalidCastException: 'Unable to cast object of type 'System.Double' to type 'System.String'.'"
EDIT: It turns out this error is because the Codification system can only handle alternate data types if it is encoding the entire table. I suppose I can see the logic here, although I would prefer a better error, or that the method was a little smarter.
I now have another issue that has cropped up related to this. After changing my code to this:
Codification codebook = new Codification(fulldata);
I then learning.Learn(inputs, outputs) my algorithm and want to use the newly trained algorithm. So the next step would be to take a bunch of test data, make sure it matches the codebooks encoding, and send it through the algorithm. Unfortunately, when I try and use the
int[][] testinput = codebook.Transform(testData, inputColumnNameArray);
It blows up claiming it could not find a mapping to transform. It does this in reference to an Integer column that the codebook correctly did not map to new values. So now it seems this Transform method is not capable of handling non-string columns, and I have not found an overload of it that can, even though the documentation indicates it should be able to handle this.
Does anyone know how to get around this issue without manually building the entire int[][] testinput array one value at a time?
Turns out I was able to answer my own question eventually.
The Codification class has two methods of using it as near as I can tell. The constructor that takes a list of column names, as well as the Transform methods both lack intelligence in dealing with non-string data types, perhaps these methods are going away in the future.
The constructor that just takes a datatable by itself, as well as the Apply method, are both capable of handling data types other than strings. Once I switched to using these two methods my errors went away.
Codification codebook = new Codification(fulldata);
int[][] testinput = codebook.Apply(testData, inputColumnNameArray);
The confusion for me lay in all the example code seemingly randomly using these two methods, but using the Apply method only when processing the training data, and using the Transform method when encoding test data.
I am not sure why they chose to do this in the documentation example code, but it definitely took me a long time to figure out what was going on enough to stop having this particular issue.
According to the docs: https://mobx.js.org/refguide/array.html
I should be able to observe an array.
observe(listener, fireImmediately? = false) Listen to changes in this
array. The callback will receive arguments that express an array
splice or array change, conforming to ES7 proposal. It returns a
disposer function to stop the listener.
However I'm getting an exception when I do so within my app:
core.js:1350 ERROR Error: Uncaught (in promise): Error: [mobx] Cannot obtain administration from Neil Clayton,Ralph Lambert,Suzie Legg
at invariant (mobx.module.js:2652)

at observe (mobx.module.js:3603)
at ObjectChangeTracker.webpackJsonp.683.ObjectChangeTracker.installObserverDirectlyOn (orm-change-detection.ts:258)
I'm unsure why getAdministration() is falling through.
I was under the impression I could pass anything into observe() (either a JS Object, real class or array thereof).
Am I mistaken that I can observe an array?
It turns out I was trying to observe a direct 'Array'.
This was happening because I was iterating the parent object keys, and getting the values by doing parent[propertyName]. Where 'propertyName' is provided by some other object (i'm intentionally leaving out specifics so as to not complicate my answer).
This was a couple of days ago now, but from memory this caused access via a getter, which had a side effect (returned a sorted array, new object, that wasn't observable).
If instead I got the value by the private field directly, and then observed the actual ObservableArray, my problems disappeared.
So, no longer convinced my question is valid.
Code is here: https://github.com/scornflake/scheduler
(but not expecting anyone to take a look, it's reasonably convoluted at the moment)
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.
I'm currently working on my first major project in clojure and have run into a question regarding coding style and the most "clojure-esque" way of doing something. Basically I have a function I'm writing which takes in a data structure and a template that the function will try to massage the data structure into. The template structure will look something like this:
{
:key1 (:string (:opt :param))
:key2 (:int (:opt :param))
:key3 (:obj (:tpl :template-structure))
:key4 (:list (:tpl :template-structure))
}
Each key is an atom that will be searched for in the given data structure, and it's value will be attempted to be matched to the type given in the template structure. So it would look for :key1 and check that it's a string, for instance. The return value would be a map that has :key1 pointing to the value from the given data structure (the function could potentially change the value depending on the options given).
In the case of :obj it takes in another template structure, and recursively calls itself on that value and the template structure, and places the result from that in the return. However, if there's an error I want that error returned directly.
Similarly for lists I want it to basically do a map of the function again, except in the case of an error which I want returned directly.
My question is what is the best way to handle these errors? Some simple exception handling would be the easiest way, but I feel that it's not the most functional way. I could try and babysit the errors all the way up the chain with tons of if statements, but that also doesn't seem very sporting. Is there something simple I'm missing or is this just an ugly problem?
You might be interested in schematic, which does pretty similar stuff. You can see how it's used in the tests, and the implementation.
Basically I defined an error function, which returns nil for correctly-formatted data, or a string describing the error. Doing it with exceptions instead would make the plumbing easier, but would make it harder to get the detailed error messages like "[person: [first_name: expected string, got integer]]".
