Teneo and Gmf - Cannot modify resource set without a write transaction [message #492171]

Originally posted by: kretschmer.e-mundo.de

Hi newsgroup,

i am initializing my model and diagram similar to the example on
elver.org. I only changed the init method to always create and save a new
model. Then I return the URI of the root diagram initialized for this
model and try to open it.

The first time I invoke the 'new' action everything is working fine, as
the model is written to the Database and the Diagram opens with the model.
But the second time i invoke the action an exception is thrown: Cannot
modify resource set without a write transaction. The model is written to
database but the diagram does not show up.

Any clues why this happens and how i can resolve this?

Hi Philipp,
I am not sure if it helps but this bugzilla contains a description of handling editing domains and GMF/Teneo/EMF:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=260940

Let me know if it solves the issue (I want to update the docs if it does).

Other links I found:
http://www.java-forum.org/plattformprogrammierung/89897-erro r-cannot-modify-resource-set-without-write-transaction.html
http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/m sg02117.html
