Modify a pictogram element in Eclipse RCP Graphiti -

-

i tried solution provided here: automatic update of graphiti diagrams in case of changes in datamodel

i trying call upadate feature in updateneeded function of class implements abstractupdatefeature:

transactionaleditingdomain domain = transactionutils.geteditingdomain(diagram); domain.getcommandstack().execute(new recordingcommand(domain) { public void doexecute() {   updatecontext updatecontext = new                                                                            updatecontext(getdiagram().getchildren().get(0).                                                                             getgraphicsalgorithm().getpictogramelement(  ));   iupdatefeature updatefeature = getfeatureprovider().getupdatefeature(updatecontext);   updatefeature.update(updatecontext); }});

in update function trying change value of text field of pictogram element:

    // set name in pictogram model     if (pictogramelement instanceof containershape) {         containershape cs = (containershape) pictogramelement;         (shape shape : cs.getchildren()) {             if (shape.getgraphicsalgorithm() instanceof text) {                 text text = (text) shape.getgraphicsalgorithm();                  text.setvalue("aaa");                 return true;             }         }     }

but getting exception:

java.lang.illegalstateexception: cannot modify resource set without write transaction @ org.eclipse.emf.transaction.impl.transactionchangerecorder.assertwriting(transactionchangerecorder.java:348) @ org.eclipse.emf.transaction.impl.transactionchangerecorder.appendnotification(transactionchangerecorder.java:302) @ org.eclipse.emf.transaction.impl.transactionchangerecorder.processobjectnotification(transactionchangerecorder.java:284) @ org.eclipse.emf.transaction.impl.transactionchangerecorder.notifychanged(transactionchangerecorder.java:240)

try executing feature using diagrambehavior

getdiagrambehavior().executefeature(feature, context);
