Re: [udig-devel] refresh a catalog item

[Andrea Antonello <andrea.antonello@xxxxxxxxx>]

Let me add something more: I debugged down the line and before returning
 from the most top members(monitor) method (i.e. the IService method),
the array contains all the needed resources, which means they are read.
The problem is, they are then not visualized. It "remebers" the previous
tree. How can that be?
