node problem [message #480700]

Hi all,

I have a node (A) which has two child references (b and c).

I add node (A) to my diagram then try adding node (b) to that node, this
works fine.
However If I try to add node (c) to Node (A) it is not drawn!!!

I have done some testing on it, and if I add node (c) to node (A) and then
add node (b) both nodes are drawn.

Does anyone have any ideas why this could be happening???

Thanks in advance,
Gary

Hello Gary,

Is there any exceptions in .log file?
do you use same domain model element (EClass) for both child nodes (b/c)?

Hi,
Yes they both use the same EClass.
No I don't get any errors.

Any ideas what it could be?

Thanks in advance,
Gary

I think this is from the log file, not sure if it helps or not:

Hello Gary,

You have to add constraitns to each of these NodeMappings showing GMF how
to represent particular domain model element - either by b or c node.
