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.emf.transaction.impl.TransactionImpl.start(TransactionImpl.java:204)
	at org.eclipse.emf.transaction.impl.TransactionalEditingDomainImpl.startTransaction(TransactionalEditingDomainImpl.java:424)

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


How can I set the style using dawn?

Thanks in advance for any help.
