I am new to GEF. I try to create a custom figure that will contain other figures. My resource is the topic "Display a UML Diagram using Draw2D" (

I have taken the tutorial one step ahead and i have created an mvc model (I added edit parts, policies and commands). The problem is that when i add to the containing figure more than 3 elements i get the error below.

Any help is appreciated.

java.lang.IndexOutOfBoundsException: Index does not exist

from the source code you can see
if (index < -1 || index > children.size())
    throw new IndexOutOfBoundsException("Index does not exist");

so the child is added with bad index, you have do debug it man.
