I tried this after your post and it seems in all cases the method is supported ..
This is the error i get when I call it ...
Exception encountered. Error
The tree node cannot be expanded or collapsed.
The node has no child nodes.
To be more specific now that I am posting the error, it seem's like it would be hard for me, lots of object digging to determine if there are children or not ...
So i would love to be able to if i got this error to catch it and go ... but it's a TestComplete error so try/catch does not work ..
Thanks for the help
