Nevermind… I found the issue. I had attempted to apply DFFS to a custom form someone built using dataview webpart in the browser.
Thanks!

Hey Alexander,
I just updated to 4.4.5.32, as I had users reporting similar behavior in one of our lists. Unfortunately, this did not fix it. Here’s a copy of the error in the console. Can you take a look? I checked for odd characters in the fields, but found nothing out of the ordinary.

No problem. Thank you for the solid tool!
Will educate the team to help avoid this in the future.
Take care!

Thanks for the reply Alex!
I figured it out. The user had pasted some text into a multi-line text field in one record, and it had some special characters. Once I cleaned up the text for them, it renders the form just fine, no error.
Let me know if you need any other details, otherwise, I think I’m set.

After using console to put a break in there, it iterates through the fields, down to “ID”, then it iterates to a blank item “”, which causes the error.

This is happening to us as well, using the latest dffs V4.4.5.22_2021-04-25 on SP2013.

Unable to get property ‘hiddenBy’ of undefined or null reference
eval code (329) (1,115855)

Tested in IE11, Edge Chromium and Chrome.

Appears to be occurring in the following lines. What is the fix?
{spjs.dffs.data.hiddenColTrackerObj[b].hiddenBy.tab=true;if(b.indexOf())jQspjs(a).hide();spjs.dffs.data.hiddenColTrackerObj[b].hidden=true}else{if(spjs.dffs.data.hiddenColTrackerObj[b].hidden&&jQspjs.inArray(b,spjs.dffs.data.initialHiddenFields)<0){spjs.dffs.data.hiddenColTrackerObj[b].hiddenBy.tab=false;if(!spjs.dffs.data.hiddenColTrackerObj[b].hiddenBy.rule){jQspjs(a).show();spjs.dffs.data.hiddenColTrackerObj[b].hidden=false}}
