In the latest Superbank release (6.8.17) we’ve just found an unusual de-referencing null object error that is affecting some critical functionality we’ve been using for a couple years which doesn’t happen in the earliest stable version of Skuid that we have in production (4.15.12).
We have an important VF page that uses the skuid:page tag as well as apex:actionFunction calls to allow us to call Apex server functions from our VF/Skuid user interface. It worked fine in 4.15.12 but somewhere in the Superbank releases this functionality has broken and causes an internal (skuid) de-reference error which doesn’t appear in our debug logs so we can’t debug it:
“Attempt to de-reference a null object — An unexpected error has occurred. Your solution provider has been notified. (skuid)”
We’ve managed to isolate the error in a simple VF/Skuid page so you can see the issue and hopefully let us know if there’s a fix or workaround. If you create and run the following small VF page (below) and click on the “De-reference error” link at the top of the page you will see the error. Under 6.8.17 it fails but under 4.15.12 it’s fine (sorry we can’t give you a more precise release version but we don’t have any other environments with older Skuid versions).
Any help would be appreciated, we’ve been working for months to try and get Superbank into production but minor Skuid issues and iOS 8 iPad issues have prevented us so far. 6.8.17 seems to resolve a number of minor issues that have been troubling us and this issue looks like the last one so hopefully this will be it.
Thanks,
Stephen
