roPosterScreen select fails

Help ! I created a "roPosterScreen" screen with 6 items in the ContentList. They all display fine but when I select items 1, 3, 5 it works as expected. When I select items 0, 2, 4 it fails. I inserted the following displays.

while true
? "wait for msg"
msg = wait( 0, port )
? "got msg 1"
? "got msg 2"
------ a bunch of code ------
end while

When the select works I get:

wait for msg
got msg 1
got msg 2

When it fails I get:

wait for msg
got msg 1

If I select it again, all I get is "got msg 1". I don't get the "wait for msg".
And like I said items 1, 3, 5 work fine.
It's like there is something wrong with the return stack.

Re: roPosterScreen select fails

We have not had any reports of "something wrong with the return stack".... I would double check your code to see if you are maintaining some state causing every other msg to work...

If you still have issues and think it's a BrightScript problem, if you post a test case I will take a look at it.

Re: roPosterScreen select fails

I found out what was going on. I had to keep putting in "stop" statements until it failed. Inserted one before and one after a call to GetTo String(). The one before generated about 100 lines of BrightScript text. The one after generated 4 lines. For some reason if you try to access a bad http url, you lose telnet debug output, which is very misleading. So because of the missing output, I was looking at code off in left field for about a week.
