[RESOLVED] [2005] Edit Item In Checked ListBox(......help help)

[maps]

I stripped part of my project and included where i need help.

ISSUE:
As in the attached sample, i have two checked listboxes ona form and a contextmenu for editing the items in the listboxes.
When i click on one or more items in the first Listbox, it brings the values related to the checked item in(Admin Level 1) to the Admin Level 2 listbox.
I populate and retrieve the values of the listboxes using an array class.

MAIN ISSUE:
When i populate (Admin Level 2 listbox) using the selectedIndexChanged Event for (Admin Level 1 listbox), i can't edit the items in the (listbox 1)!, yet i can edit the items in listbox 2!
To check this, try commenting out the routine that populates listbox 2 and then Edit the items in listbox 1. It works perfect, but when you uncomment it, it gives an error "Unable to cast object of type 'System.String' to type 'EditCheckedListBox.cls_ListComboItem'"! I get puzzled.
What am i getting wrong here. The SQL Statement is correct and it seems it gets called again.
Please help me.

Note: To Edit, right click an item in the listbox and click Edit.
I am sorry for not commenting out the code. But i presume its pretty
simple to understand for an average man
