Setting object on Parent panel and checking its value on
grand-child panel
Dear Forum,
I have set a drop down list on a parent panel A and at one point or another
I need to check the value selected from that drop down on a grand-child
panel.The structure I have is as follows:
Parent Panel A contains
Child panel B which contains
grand-child panel C.
I have set object O as ModelObject of the drop down list in panel A.
How can I check the value of Object O in grand-child panel C?
I have passed the Object O as a parameter when initializing the panels, but
when checking the values of object O in grand-child panel C, they have not
been updated. I only see the values that O has been set with when
initializing panel C.
I could pass parent panel as a parameter to the child and grand-child panels
so I can call parent.getObject(). But is there a better way to do this?
is it possible for panel C to read the updated values of Object O without
the need to pass panel A to the constructor of grand-child panel C?
Thanks in advance and I apologise if I'm rather unclear in my question.
Lucas

dont pass the model object itself, pass the model.
