I have a tabnavigator and in tab 1 is a tree control. When a
node in the tree is clicked I'm trying to switch to tab 2 and set
the text of a label in tab 2. It does switch to tab 2 but when I
try to assign the value of the label text I get the error...
TypeError: Error #1009: Cannot access a property or method of
a null object reference.
What's interesting is if I go back to tab 1 and click another
node, from then on it works fine. I've tried a couple of things but
neither seem to work. I've set up a string variable equal to the
text of the selected node and then when I switch to tab 2, I set
the text equal to the string variable. Same error. Then I thought
that maybe until tab 2 gets into view and loads that label, I can't
access it. So, to do this I set up a function to call on
creationcomplete that sets the selectedindex = 1 and then = 0 so
that it quickly loads tab 2 and then goes to tab 1. But, in this
case it's not going back to tab 1 but instead stays on tab2. So,
basically, what is the best way to set the text of a label on tab 2
from an event on tab 1? Thanks.
