Programatically adding nodes to the GMF diagram [message #685905]

HI,
I have been working on this topic since last week. I have a problem in adding nodes to the GMF Diagram.
I have a systemView which contains multiple systemBlocks and each systemBlock contains multiple parameters. My question is if i want to add the parameter along with the systemblock and systemview it is not possible. It gives me a write transaction error.

When i add only the systemView it is fine, but when I try to add a full nested block (systemview containing systemblock containing parameters) I get the error.

Are there any other tutorials other than the one in Eclipse website, I have already checked the tutorial of Custom Actions, but that is not what I want.

Can anyone help me with this !!!

Thanks and Regards,
SPRao

You need to make sure you use the command stack when you programatically add nodes. If you simply use setor add methods it will not work.
You need to do something like:

SetCommand cmd = SetCommand.create(.....)

then something like:

  someEditPart.getEdittingdomain().getCommandStack().execute(cmd);
