Hi,

I found that when I use java service to add a new semantic element into the model, for example:

FuncUnit unit = MetamodelFactory.eINSTANCE.createFuncUnit();
chip.getFuncUnits().add(unit); // chip is a semantic element already in the model, which holds a bunch of function units

after the service is called, an arrange action will be triggered automatically, due to the executeLayoutDueToExternalChanges() in SiriusCanonicalLayoutCommand. I'm working on create a semantic by java service and set its location and size by directly change its basis gmf node, but the auto triggered arrange action ruins my previous steps of setting the gmf node's location and size.

So is there any way to prevent the arrange action from auto trigger? I cannot use SiriusLayoutDataManager because besides location and size I also had to set its style and other graphical informations. Just need a hint about how to disable the auto arrange from SiriusCanonicalLayoutCommand. Any advice helps a lot.

Thanks.

Hi,

Maybe you can add a fixed layout to the diagram or even a custom layout if nothing else works, I believe that there shouldn't be an automatic arrangement that way.
