Are there any log, trace files that VE parses those composites. The
reason I looked for the log/trace is because my composite doesn't show up
in VE, and if I hover the mouse over it, it shows this warning message :

xxxx : java.lang.RuntimeException(null)

where xxx is the attribute that I am trying to set on my composite.

Thanks.

Try the workspaces .metadata/.log file.

Thanks Rich,
The log didn't show those exceptions, however, I was able to figure out
why there was the java.lang.RuntimeException(null).

There's still one exception when hover the mouse over my composite in VE.
It gives ClassNotFoundException. Here is an example of generated code
when drop from Palette.

private void createMyComposite()
{
myComposite = new MyComposite(this,SWT.NONE);
myComposite.setMyProperty(new MyProperty(2)); // @jve
}

VE complains that MyProperty class is not found. I have tried to extend
"org.eclipse.jem.proxy.contributors" to add my jars to VE JRE's classpath,
but no luck. Because of this exception, my composite doesn't render in VE
at all.

However, if I modified the code something like this, close and edit the
file again, it magically displays in VE.

private void createMyComposite()
{
try
{
myComposite = new MyComposite(this,SWT.NONE);
myComposite.setMyProperty(new MyProperty(2)); // @jve
}
catch ( Exception e )
{
}
}

I got it to work by specify the whole qualified classname, ie:

myComposite.setMyProperty(new myPackage.myProperty(2));

Thanks.
