xpages - Checkbox null

Question

I was pointed to this site for my issue below.

I have borrowed the checkbox code from OpenNTF.org. The project is - http://www.openntf.org/internal/home.nsf/project.xsp?action=openDocument&documentId=CDD107F4006F7D5C8625775F001B8C61

I have integrated it into a xPage and it works fine when run in the notes client on local, in the web browser and on handheld devices. But when run on a replica on a domino server, the value for the number of columns comes into the is null. The domino server is 8.5.3 FP1.

Not sure why is only errors when on the domino server via the notes client when it works just fine in the client locally.

Thanks, Walt

The script interpreter error is "'compositeData.FieldValues' is null". As is true in the context of any Custom Control, compositeData is the variable that refers to the map of properties passed into the Custom Control. Hence, if compositeData.FieldValues is null, then whatever expression is assigned to the FieldValues property of the Custom Control, that expression is evaluating to null.

In your case, the expression compositeData.FieldValues.length throws an error, because null does not have a length (...or any other properties or methods, for that matter).

You've indicated that this works fine in the following scenarios:

Notes client, local replica
Browser accessing server
Mobile device accessing server

What all three scenarios have in common is that the code is running on local. When you access an XPage via the browser (including mobile), you're accessing some server, but the code that executes is local to itself... it doesn't have to make an NRPC call to another Domino server to run the code.

So the one scenario where it's failing is the one scenario where that's not true: accessing a server replica from the Notes client. I'm guessing that the expression you're passing to FieldValues is using @DbLookup() or a similar operation but not properly accounting for what server the code is running on, causing it to pass null to the Custom Control.
