Override property problem [message #119489]

I have class which has String attributes

For example

public class Person{
String name;

public String getName(){
return name;
}

public String setName(String name){
this.name=name;
}

}

Let's say that this class is visualised in the VE editor and the
attribute "name" is displayed and can be edited in the Properties view.

I do not know how to associate my own cell editor (for the Properties
view) with the attribute name.

I have tried to use the approach from the "Extending The Visual Editor:
Enabling support for a custom widget tutorial" I made something like this:

I created the Person.override file and made all things to make it work.

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:org.eclipse.ve.internal.cde.decorators="http:///org/eclipse/ve/internal/cde/decorators.ecore"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
xmlns:event="event.xmi">

<event:Add featureName="eStructuralFeatures">
<addedEObjects xsi:type="ecore:EReference" name="name"
unsettable="true">
<eAnnotations
xsi:type=" org.eclipse.ve.internal.cde.decorators:BasePropertyDecorator "

cellEditorClassname="me.testpackage/me.myTestPackage.MyPersonCellEditor "/>
</addedEObjects>
</event:Add>

</xmi:XMI>

The problem is that the "name" attribute of the Person class is still
edited by the default editor for the Strings:-(. (The override is
applied to the person class).

That should of worked. Were there any errors logged in the .log file? Do
a clear cache and try again, we may of cached the old override file and
so didn't know it had changed.

To clear the cache:

1) Open a VE then close it and all VE's.
2) Do a Project->Clean...->Clean All Projects
3) Wait for build to finish
4) Open your VE.

Another possibility is that your override file is not being picked up.
First are you sure your container is in your classpath? That is how we
determine which overrides to process.

I have found the problem, indeed the errors were logged, there was an
syntax error in my .override. I must admit that I hate editing those
files:-).

Thanks for help
