Hello everyone,

another question to the audience. How is it possible to run a delete
command in a recursive order?
For example, a node in a tree is deleted. But all children that come
after that node have to be deleted too.
I thought that the commands would work like this automatically, but
somehow it does not show in the editor (if it is not once again the
problem using the directgraph layouter...)
Thanks for helping out.

Hi again,

here is a first try on how to get it working, well it does work. I just
wonder if there is a better place to put it, it seems a little crude to
produce a deleteCommand inside a deleteCommand.

This Code-Snippet is part of the DeleteCommand, the class that is
extending Command :

public void execute() {
if(child instanceof ParentModelElement &&
(ParentModelElement)child).getChildren()!=Collections.EMPTY_ LIST)
{ for(int i = 0; i <((ParentModelElement)child).getChildren().size(); i++)
VisualEditorModelElement vEME =
(VisualEditorModelElement)((ParentModelElement)child).getChi ldren().get(i);

DeleteCommand cmd = new DeleteCommand((ParentModelElement)child, vEME);
sourceConnections = child.getSourceConnections();
targetConnections = child.getTargetConnections();
