Can't set popup

Hi,

I can't set popup unless app mode is "none".

Here is the code, I am using SPB16.6 with hotfix030.

Thanks a lot.

 (defun cbc_select ()
let(()
    cbc_select_popup = axlUIPopupDefine( nil (list     (list "Complete" 'cbc_select_complete) (list "Cancel" 'cbc_select_cancel ) ))
    axlUIPopupSet(cbc_select_popup)
    axlClearSelSet()
    axlSetFindFilter( ?enabled list("noall" "COMPONENTS") ?onButtons list("noall" "COMPONENTS"))
    axlSelect(?groupMode t ?prompt "Select objects you want to highlight.")
);let
);defun
