I am attempting to use a Feature Map in EMF in order to allow for the editing of arbitrary types in an editor.
I have managed to achieve this so that it is working in the default EMF instance editor but I wish to use ECP in order to build a useful GUI for my plugin. When I attempt to use a control to display this I get the following error:
org.eclipse.emf.ecp.view.spi.renderer.NoPropertyDescriptorFoundExeption: No Property descriptor was found for the feature "properties" of "Resource". Make sure, the corresponing edit bundle is started.

Any help would be greatly appreciated.
Make sure that the property 'Property Type' value is Editable under the Edit category in .genmodel.

i had the same problem probably you have a space somewhere in the name of your folder
It worked for me when I copied the dataset to the directory where my notebook is present. However, it does not work when I set a different filepath and try to load from that filepath
I am getting following exception if I place dummy array. eg, in Security/RelatedSecurities/RelatedSecurities. I tried to build a json schema from the response where it is empty. But if I use json validator it gives sytax error "array must have atleast one element". So I used the dummy array elements. After that I do not get syntax error but the validation fails with following error. Actual not matching with expected.
I will be happy to share the response and json schema if anyone is willing to help.

However, when executing queries from the console, the data I get is the correct. I'm not very sure what's failing here, as I don't have any problems when using pgAdmin.
Has this happened to anyone else?
I solved the issue by re-downloading the JDBC driver 0xDBE was using. Right-Click on the Data Source, then go to preferences and erase the driver files currently being used and download them again.
You have to restart IDE after redownloading the driver for the changes to take effect.
I was able to fix this issue by opening the data source settings page (where you enter the DB credentials) and switching to tab Options and enabling Introspect using JDBC metadata:

This is happening because of improper setup of Axis2.
Steps:
Download Axis2 : Link--> http://ws.apache.org/axis2/download.cgi
Point the Axis2 runtime dir in eclipse : Menu--> Windows--> Preference --> Web Services--> Axis2 Preferences
Your code throws a NullPointerException at
PreServiceDevelopCommand.java:143
NullPointerException means that you wanted to use a reference which was not initialized. Most common scenario is that you want to use a member or call a method of an object which was not initialized using the new operator or a factory method. Check the file where the error occurs at line 143 and see what could be null there.
Official description from the docs:
Thrown when an application attempts to use null in a case where an
object is required. These include:
- Calling the instance method of a null object.
- Accessing or modifying the field of a null object.
- Taking the length of null as if it were an array.
- Accessing or modifying the slots of null as if it were an array.
- Throwing null as if it were a Throwable value.
Just try to clean the pojo class for which you are trying to generate web service.
Clean the class and compile again.
It worked for me.
Deleting the client which you have already created will solve the problem.
I have some tests that recently failed with the following reason: No X11 DISPLAY variable was set, but this program performed an operation which requires it.
Here's the complete stack trace:

In the mentioned line of code is just this:
return new JDialog();
I guess is related to the Jenkins environment not having something enabled. How can this get fixed?
I can disable that test, but why should I?
You need to run your build inside a virtual (headless) graphical environment, using XVNC (or XVFB). See wiki.cloudbees.com/bin/view/DEV/Testing+GUI+applications.
Edit 20/01/2016:
The link above no longer takes you to a page with relevant information. This link shows the page as it was at the time: https://web.archive.org/web/20120717015714/http://wiki.cloudbees.com/bin/view/DEV/Testing+GUI+applications
You might also consider refactoring your code a bit to use a mock service so that tests do not need to load AWT. This will likely make tests faster and more reliable, as well as minimizing the chance that they will fail in novel environments such as a CI server.
