Overwriting vars crashing channel?

Archived

Hi all -
I could really use some help debugging this. I’m trying to modify a private channel so that the registration process happens before the home screen loads, but the channel keeps crashing without any error message on the debug console.

I’ve been working through it and it seems that whenever I overwrite a pre-existing variable (screen, rsp), the channel exits without an error. I don’t really understand why it’s doing that since the code seemed to work that way before and I’m just changing the order of things.

First it was happening because my CongratulationsScreen was using ‘screen’ and in the preShowHomeScreen sub it was dying at the line:

screen = CreateObject("roPosterScreen")

so i changed the showCongratulationsScreen sub to use ‘cscreen’ and now it’s failing in LoadCategoryFeed on the line:

rsp = http.GetToStringWithRetry()

I assume it’s failing because the ‘rsp’ variable is already defined during the registration process.

I’d like to note that the failure only happens the first time when the user has to go through the registration process. After the UID is stored, and the registration bypassed, the revised channel works as usual.

Should I be able to reuse the variables, does anyone have any ideas what’s going wrong?

Thanks RokuChris -
I’m pretty sure it’s crashing because I have debug code like this:

Function load_category_feed(conn As Object) As Dynamic
    http = NewHttp(conn.UrlCategoryFeed)
    Dbg("url: ", http.Http.GetUrl())
    print "made it here 04a"
    m.Timer.Mark()
    print "made it here 04b"
    rsp = http.GetToStringWithRetry()
    print "made it here 04c"

and in the debug console I see

made it here 03a
url: http://www.mysite.com/roku/categories.xml
made it here 04a
made it here 04b

With no “04c” line, while the roku is back on the home screen outside my channel.

I tried following that suggestion you linked; it didn’t work at first, when I didn’t place it at the VERY beginning of my Main Sub, but now that I did, it looks like everything is working correctly!

Still don’t understand in light of what I posted above, but hey, it’s working so I’m happy now - THANK YOU :slightly_smiling_face:
