Hello all,
I have the following problem:
In my project there is one main editor and three subeditors. There are
three specific top level nodes, everyone represents a subeditor. In
every subeditor it is possible to create an object/node (which
represents a package/specialized package for every editor). Every time
when I create a package in my second subeditor, close the editor and do
a right click on an object in the main editor I will get a NPE from the
WorkspaceSynchronizer. This behavior occurs only in the second
subeditor. I compared the configuration
(Ecore-Model,Gen-Model,gmfMap,gmfgen, plugin.xml) between the editors
but I didn't find the error.
I found one entry in the newsgroups, which seams to be similar:
"syncronisation error with diag partitioning? [message #484229]".
Unfortunately there is no solution in this entry.
I think the usage of teneo for the persistence shouldn't be a problem.
Maybe someone has a hint for me, where I could find the error?
Thanks for the answers, I'm still searching the error.
Dennis

Hello all,
I found the problem. In the ???DocumentProvider exists a
disposeElementInfo(...) function. In this function the
ResourceSetInfo-object will be disposed, but afterwards for creating a
context menu in the main editor the resource is needed. I use a shared
single editing domain.
The only question I have, is it correct, that the navigator selection
points to the freed resource?
I think it have to point to the element in the current open editor, or
I'm wrong?

Hello Dennis,

Then you have to count editors openned with this EditingDomain and dispose
it only on closing last eidtor - corresponding code should be modified manually.
