Hello everyone,
I'm trying to set the routing-style of my dawn-diagram to rectilinear but I'm having some problems doing so.
When I try to set the routing style as proposed in the gmf newsgroup ( http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/m sg19825.html) I get the following exception.
Caused by: java.lang.IllegalStateException: Cannot activate read/write transaction in read-only transaction context
at org.eclipse.emf.transaction.impl.TransactionalEditingDomainImpl.acquire(TransactionalEditingDomainImpl.java:576)
at org.eclipse.emf.transaction.impl.TransactionalEditingDomainImpl.activate(TransactionalEditingDomainImpl.java:508)

at org.eclipse.core.commands.operations.DefaultOperationHistory.execute(DefaultOperationHistory.java:511)

How can I set the style using dawn?
Thanks in advance for any help.
