Hello,
I need to edit some features of some model objects via plugin eclipse.
My method to set "devicename" property of "SystemMode" object is defined like below :
public void setDevicenameofSystem(){
System.out.println(s.getSemanticResources().iterator().next());
XMIResourceImpl xmiressourceImpl = (XMIResourceImpl) s.getSemanticResources().iterator().next();
final SystemModeImpl var = (SystemModeImpl) xmiressourceImpl.getContents().get(0);
System.out.println(var.toString());
final ModelAccessor ma = s.getModelAccessor();
System.out.println("can edit device name : " +ma.getPermissionAuthority().canEditFeature(var, "devicename"));
try {
TransactionalEditingDomain ted = s.getTransactionalEditingDomain();
CommandStack stack = ted.getCommandStack();
System.out.println(ted.getResourceSet());
RecordingCommand cmd = new RecordingCommand(ted) {
@Override
protected void doExecute() {
var.setDevicename("Test");
}
};
stack.execute(cmd);
}
catch (ServiceException e) {
e.printStackTrace();
}
}
I get as results :
ExternalJavaActionModelAnalysis
Work Session :Local Session: representations.aird
org.eclipse.emf.ecore.xmi.impl.XMIResourceImpl@10412e2 uri='platform:/resource/Demo/My.modemodeling'
modemodeling.impl.SystemModeImpl@f508fb (devicename: SystemMode)
can edit device name : true
!ENTRY org.eclipse.equinox.registry 4 1 2015-06-08 12:32:51.363
!MESSAGE Plug-in "xxx.modelanalysis" was unable to instantiate class "xxx.modelanalysis.ExternalJavaActionModelAnalysis".

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)
....
I read documentation about "TransactionalEditingDomain", "Session", "ModelAccessor" and "PermissionAuthority" but I don't find a clear example for my requirement.
Thank you.

I forgot to add, if you use this code in a Java Service, executed from a
tool with a set operation, you should have the context (change context
operation) on your SystemMode element. In your java service, you should
have a SystemMode as first parameter (public void
setDevicenameofSystem(SystemMode systemMode){). Then in your expression
you can directly call it [setDevicenameofSystem()/] as the first
parameter will use the current context.

Steve

Hello,
I am glad you resolved the problem.
Ok you were using an External Java Action. I am surprised of the
read/write transaction exception. However, the External Java Action is
already executed in a transaction so in that case you did not need a
RecordingCommand executed on the command stack. This embedded execution
probably caused this issue, but this should be reproduced on our side to
verify.
Regards,
Steve
