multicolumnlist crash

[Metabug]

I made two multicolumnlists with list items inside each. When I try to shift click to select multiple items across these two lists (i.e. select an item from one list, shift click an item from the other list), I get a exception "the given listboxitem is not attached to this multicolumnlist". It doesn't happen all the time, but it happens pretty frequently.

Hi!

Absolutely required:
- CEGUI Version?
- Full exception text, including any member function name?

Would be nice:
- Minimal code to reproduce?


Having requested the above, I think it could be a dangling pointer to a removed item. Shift-select is used in selecting a range, so if the previous 'last selected' item in a list was removed, a subsequent range selection could cause this issue if we are leaving a dangling pointer.

Once we have at least the first couple of bits of info, I'll check it out further.

CE.
