Martin,
thanks for the answer!
However, as I said, I *did* manage to open it on pageload. The problem is to
open it programmatically at any point of a member function of the Panel
instance.
Ideally, I'd like to do something like:
public MyPanel() {
// panel creation
add(...)
// ...
// business logic
// somestuff
// ...
Boolean userConfirm = modalDialog(...);
If( userConfirm ) {
// other stuff
If( modalDialog("Another question") ) {
// more stuff
}
}
// other stuff
}
M.

Hi,
See
http://stackoverflow.com/questions/4765790/how-to-open-modaldialog-on-pageload
I think the second approach/answer is better.
