This is the first form I've created with the responsive layout box checked and I get the following error. I downloaded the pdfViewer to test, but haven't even tried using it yet so I don't know why there would be a reference to it when creating the form.
"Unable to get property 'firstElementChild' of undefined or null reference
http://localhost:8080/pdfviewer/pdfView ... .js:6203:5
TypeError: Unable to get property 'firstElementChild' of undefined or null reference"
How do I get rid of this error so I can actually build the form.
