Hi.
I've this Custom Task and I extended CustomShapeFeatureContainer, and overrided getCreateFeature method, like this:
@Override
public ICreateFeature getCreateFeature(IFeatureProvider fp) {
return new CreateCustomShapeFeature(fp, Messages.AgoraMailMessageFeatureContainer_2, Messages.AgoraMailMessageFeatureContainer_3) {
@Override
public Object[] create(ICreateContext context) {
Object[] result = super.create(context);
if (result[0] instanceof ServiceTask) {
final ServiceTask st = (ServiceTask) result[0];
ModelUtil.addAnyAttribute(st, AgoraRuntimeExtension.ACTIVITI_XMLNS, "type","type", "mail"); //$NON-NLS-1$ //$NON-NLS-2$ //$NON-NLS-3$
st.setName(Messages.AgoraMailMessageFeatureContainer_7);
}
return result;
}
};
}
Apparently, I can't set the name of the task with some other value as I am doing. It throws :

How can I set the name of the task without this exception?
I thought inside this method the operations were wrapped within a transaction.
As far as I can notice, changing the name causes UpdateFeature behave differently.
Any hint??
Thanks in advance

Hmm, that's odd...I just tried this using the customTask sample plugin and it worked. The create() method should definitely be already wrapped in a write transaction - not sure what's going on here.
Is it possible for you to try this using the latest build?
