Hi Jon,
It's not actually rendering at all. If I try to re-add the web part I do see a 302 error:

GET /labkey/project/Oregon%20Pancreatic%20Tumor%20Registry/addWebPart.view?pageId=Search&location=%21content&returnUrl=%2Flabkey%2Fproject%2FOregon%2520Pancreatic%2520Tumor%2520Registry%2Fbegin.view%3FpageId%3DSearch&name=Search+-+Main HTTP/1.1

That's it though. Nothing in intelliJ or the console.

This is just since I removed the 17.2 module from gradle and put the 17.1 ant version of the *.module in there.
