We created them in BIDS then uploaded to our Solution Solution.
I checked into the SSRS logs and the Platform trace. There were no errors or warnings in either while attempting to run the report. The Javascript error I'm seeing only happens when running "for all records on all pages in the current view" (as in the OP). If I run for "all applicable records" it works fine.
For most of my custom reports we're using a CRMAF_xxxx alias and for one we are using Explicit filtering. Both types are showing the same behavior, but we discovered it first on the report that was using explicit filtering.
When attaching IE's JScript debugger to it, I can see that the error is thrown in 'global.ashx?ver=1728984074'. The statement in question says 'return contextNode.text' and the watch tells me that contextNode is null.
That screen capture shows the full Stack Trace as I can see it in IE's F12 tools.
Let me know if there's anything else I can dig up on this end to try to sort this out.
Thanks,
