Roku Developer Program

[mosbat]

I have a BrightScript file that's used in registration and activation of Roku boxes for a private channel subscription. It was written about 2 years ago. It continues to work fine with Roku 2 models. However, when used with any of the Roku 3 models, it aborts. There is no change indicated in the Roku SDK that explains this behavior. I have copied the debugger output, below. I know it is of limited value in troubleshooting this issue. If possible, I appreciate receiving an email address to which I could send the actual brs file (or the complete app).
Thank you.

In my .brs file, line 124 and subsequent lines referenced in the debugger are scripted as follows:

		msg = wait(0,regDialog.GetMessagePort())
		if msg.isscreenclosed() return -1
		if msg.isButtonInfo() return -1   ' Info pressed again, dismiss the info overlay
		if msg.isbuttonpressed() and infotype=0 then

That's no abort. See where it says

Break in 124
124: msg = wait(0,regDialog.GetMessagePort())
Backtrace:

That just shows you have pressed Ctrl-C in console to interrupt the program while it was waiting for event on the dialog port.

On a side note, can you edit your message and put [code ][/code] brackets around the code/printouts you post? Makes it easier to read; there is even formatting button on toolbar for that, mark code and click |Code|.

[JohnBasedow]

I know you have an 'infinite' wait with wait (0, ...), but you still want to make sure the msg isn't invalid before you access it.

But, based on this trace, it looks like you have caused it to abort via the console.

[mosbat]

I have provided an updated debug and a more complete section of the code. The only time CTL-C is pressed is at the outset, so as to enable the micro debugger. I emphasize that the code works perfectly fine with Roku 2 series. However, in subsequent versions something has evidently changed with the "showRegDialog" function. I appreciate any guidance. Thank you.

JohnBasedow already provided the answer. Before calling methods on the msg object returned from wait, you need to verify the type of the object. You should be doing something like this:

msg = wait(0, regDialog.getmessageport())
if (type(msg) = "roSpringboardScreenEvent" then
    if msg.isscreenclosed() return -1
    if msg.isButtonInfo() return -1 
    ' etc
end if

You've been lucky because on the Roku 2 you're not getting any events other than the type you expect, but you shouldn't depend on that.

You provided WAY, WAY TOO MUCH text from the console, with 3 stack traces - 2 from ^C and 1 from the error at the end. Above I trimmed the output only to the relevant part - that makes it easy to spot. See, msg is invalid and you are calling isScreenClosed() on it, so it rightfully bitches there is no such function. It is possible that you got invalid there because you interrupted with ctrl-C the script before and then "c"ontinued it - i seem to remember in that case invalid spoke is being thrown in the message wheel. The solution is as pointed out, check type(msg)="..." before calling methods. Or "if msg<>invalid then ...", whatever.

[mosbat]

Upon further debugging found that the code stops executing at the following function:

Function displayRegistrationScreen() As Object
    regsite   = "" + m.UrlBase
    regscreen = CreateObject("roCodeRegistrationScreen")
    regscreen.SetMessagePort(CreateObject("roMessagePort"))

Any guidance is much appreciated. Reminder, this works in Roku2. The problem is limited to Roku3. Thank you.

[RokuJoel]

What firmware version on your Roku3? I just tested with 5.4 b3340 on a Roku3 and I don't see any issue:

sub main()
    regsite   = "http://"
    regscreen = CreateObject("roCodeRegistrationScreen")
    regscreen.SetMessagePort(CreateObject("roMessagePort"))
    regscreen.show()
    while true
    
    
    end while
end sub

I don't think this is the cause of your problem, although the value of m.UrlBase could cause a crash if it was not a string.

[mosbat]

I tried replacing the line -- regsite = "" + m.UrlBase -- with the actual URL; but results were the same. I am using the HDMI Stick 3500X, running FW Version 5.4, B2525 (which I believe is the latest released update). A colleague, using Roku 3 "STB model" is also getting the same errors.

You referenced B3340. Are you saying that you tested the SuperMediaPlex private channel with B3340 and there were no activation screen issues?

Incase not had a chance to test, wonder if I could impose upon you to test SuperMediaPlex for yourself. https://owner.roku.com/Account/ChannelCode/?code=supermediaplex

Thank you.

[RokuJoel]

Hi, no, I tested your little snippet of code and determined that your displayRegistrationScreen function is not failing due to anything in these two lines of code:

   regscreen = CreateObject("roCodeRegistrationScreen")
   regscreen.SetMessagePort(CreateObject("roMessagePort"))
