Using simple popup menu..

i have a menu as follows:

I wanna using this menu as popup in my datawindow(dw_category1) which is in a tab object (tab_category.tab_page1)

following is my code in rbuttondown event of tab_category.tab_page1.dw_category1:
m_category.popmenu(PointerX(), PointerY())

following is the error message:
Null object reference in rbuttondown event of object dw_category1
1 Solution
Declare an instance variable
m_category mymenu

In window open script (or treeview create script):
mymenu=create m_category

On rbuttondown will work fine your code:
mymenu.popmenu(PointerX(), PointerY())

A comment:
I usually create menu object level variables, that I set before, f.e.:
treeview tv

On rbuttondown You can write this:
mymenu.popmenu(PointerX(), PointerY())
