setVisible() and invalidate() don't work when they are in if/switch~case statement.

[emi1123]

I made some containers in 1 screen. (please refer to attached image)

I wanted to handle these containers depends on h/w key.

e.g. temp key is pressed, all of the containers in HDT_POPUP_GRAPHIC_SCREEN must be disabled. only

main_graphic_temp_container will be showed up.

However, 

main_graphic_temp_container.setVisible(true);
main_graphic_temp_container.invalidate();

doesn't work normally, when these codes are in the switch~case statement.

I tried to move these codes to the end of the setupScreen(), not in the switch~case statement.

In that case, 

main_graphic_temp_container.setVisible(true);
main_graphic_temp_container.invalidate();

works normally.

Am I wrong to use these two (setVisible, invalidate) methods?

It should be fine.

Can you make sure you do reach that case by adding a print or setting a breakpoint?
