I’m using SP 2013 to create custom task forms, but also editing the aspx code to make some columns read only, add comments, etc. Within SPD, in --> List and Libraries – Tasks – Forms, I create three new edit forms. AAA_Abcdefgh111.aspx, AAA_Abcdefgh112.aspx, AAA_Abcdefgh113.aspx. Each used for a separate task in a workflow.
I then custom edit these forms for read only columns, etc.
Once saved and I preview in browser, guaranteed one of the three forms show in IE as blank. Upon reviewing the aspx code I see there is nothing within the
<ZoneTemplate></ZoneTemplate>. Its as shown = blank. When place back the missing aspx code (saved to external file), the form in question works and one of the other three forms becomes blank.
What the @%$#!!
