I've a node with some custom code that draws an image (png, jpg whatever)
as content, and gets pretty stretched and extendend to its bounds as you
move or resize this node.
I've made another resizable node that act as container table and another
node more contained in the table as a colum. This column has a fixed width
you cannot resize, and you can drop other nodes in it.
Eclipse freezes and must be stopped manually when you instantiate
directely one of those image-nodes above in my column.
Instead, if you instantiate the picture outside, and then dragndrop it in
the column it works well.
I must correct this problem but cannot find the reason, it seems a matter
of ValuesEditParts calling superclasses each other and I got completely
lost.
This is the log I have as the error:
