I am developing a custom form .
Below is the requirement:
There are 2 windows w1 , w2 . and 2 content canvas c1 , c2 respectively .
C1 has many columns . When I double click on one item of C1 , i want it to show W2 window which only has one column i.e. error message.
I tried to use show_window('W2') and go_item .. but it is opening window W2 behind W1 .
I need to show W2 on top of W1 . Please suggest .
