| EContentAdapter vs Listening to commands [message #989818] |

Hi,
We have a Editor (not using emf.edit) which is based on EMF model.
We want that on change of a EObject or its content, Editor should adapt based on notifications. We used EContentAdapter and it worked fine.
We just came across a situation we have do some set of operations on a EObjects content. During this operation (many content of EObjects are changed and implemented by RecordingCommand) we get into a situation where Editor might become inconsistent. Hence we want to notify only on completion of the command.
One solution we have to stop listing via EContentAdapter but rather listen to EditingDomain() and only reach when some objects are changed. Via editing domain i think the notification only come when some command is fully executed and not between.
Do you think this approach will be good or is there a better solution ?
Thanks and Regards,
Ashwani Kr Sharma

Yes, listening to the command stack is a good way to know when a set of
related changes have all been completed.
