Android Question How to modify buttons on layout files placed in tabHost

[Rafal]

I've problem when I try to changing buton enable/disable from main activity if buttons are placed in other layout files, which I use with tabHost.
For example when I try to use Buton1.enable = False I can see abnormal termination.

Could you help with this ?

Can you upload the project or post the code that adds the tab pages?
