Hello,
I write a custom panel to manage a wizard and visual editor works well
with it but i have an error in the error log when i open the panel:
java.lang.ArrayIndexOutOfBoundsException: -1
at org.eclipse.emf.common.util.BasicEList.get(BasicEList.java:5 14)
i have some custom attribute in my bean, i think it can come from it, but
the
error is not clear...
if you remove the comment // @jve
visual editor goes in nullPointerException!!!
do you know to remove the error ArrayIndexOutOfBoundsException ?
Thanks

It is a bug, but the workaround is to change maChaine to:
String maChaine; // @jve:decl-index=0
This forces maChaine to be in the model even though there aren't any
visuals referring to it.
Please create a bugzilla bug so that we can fix this for others. Please
attach your class to the bug as a example of the error.
Also, please include the following text so that we don't need to
reinvestigate the problem again.
------------
The problem is that String maChaine's bean was never added to the model.
But there was an AnnotationEMF created for it. This had an annotates
reference to it, but since the maChaine bean was not in the model, it
was a dangling reference. The standard ResourceImpl expects references
to have a resource, so that it can calculate the URI. But without being
in a resource it didn't know what to do so it punted to -1.
Fix needs to remove Annotiations for any bean that is deleted from the
model. It currently leaves them around.
