Whenever I'm adding a node to the diagram by drag-n-drop from the palette, I'm getting this message in the console:Thank you.
“Model changes should occur within a transaction – call StartTransation and CommitTransaction”
Where/when should I call the StartTransaction & CommitTransaction?
Another issue is, whenever a new node is added to the diagram, I check if the node of same type has already been added. If so, model.Undo function is called. This is working fine. The problem is, icon of the node as displayed in the palette is visible in the diagram.
I’m using diagram in tabs, if I switch to another diagram & switch back to it, the icons are not displayed. How do I prevent the icon from being displayed?
I’m using GoXam 18.104.22.168 for WPF
