[V8i C++] Starting a command with a CmdItemListRsc and a modal dialogBox

I'm writing a command that utilizes a CmdItemListRsc and a modal dailogBox. The modal dialogBox is used to gather a username/password keyin for a database connect string. I call that modal dialogBox prior to calling mdlState_startModifyCommand(). My issue is that when the CmdItemListRsc is "created" (once the username/password are enterd and the modal dialogBox dismissed), all I get is a blank toolSettings dialog. If I remove the call to the modal dialog (mdlDialog_openModal() ), then I get the populated CmdItemListRsc. I've tried moving the modal dialog call completely from the function that invokes mdlState_startModifyCommand(), but the CmdItemListRsc still comes up "empty". Is this an issue with the combination of a modal dialog box being opened and the CmdItemListRsc?

Thanks,

Bruce
