Oracle Forms Call Certain Canvases of Multiple Forms from Custom Menu (mmb)

I have one main form ("users.fmb"), one other form ("cards.fmb") and one custom menu ("menu.mmb"). I want to call canvases of forms according to which menu item selected.

For example: When I choose 1. item of menu, call canvas A of "users" form. When I choose 2. item of menu, call canvas B of "cards" form. Menu("menu.mmb") is related with main ("users") form.

How can I do this?

I tried to use 

CALL_FORM, OPEN_FORM, GO_BLOCK, SHOW_VIEW, SET_WINDOW_PROPERTY

methods in different ways but it not worked.

if your menu is only attached to users.fmb, you won't be able to call again users.fmb from cards.fmb (except by exiting cards.fmb).

Also if you call again users.fmb from cards.fmb you will have 3 forms in your calling stack (users.fmb -> cards.fmb -> users.fmb), which is not a good idea.

I guess you would have to create another form acting as the main screen from which you can run either users.fmb or card.fmb (you can use CALL_FORM for this).

Also you can use SHOW_VIEW to display a specific Canvas but you will have to do this in the targeted Form. You can pass the canvas name as a Form parameter (called e.g. "navigation_canvas") and in the WHEN-NEW-FORM-INSTANCE trigger, if this parameter is not null you can then navigate to the desired canvas using SHOW_VIEW(:parameter.navigation_canvas)
