How I chased and exorcised an Umbraco ghost.
The YouTube Creators are doing free video production workshops Wednesdays at noon. The workshops will cover pre-production, production, and post-production.
You drop in on any that you like or go back and view recordings of the ones you’ve missed on the YouTube Creators Google+ page.
In addition to the opportunity to learn more about video production, this is a chance to see how G+ works as a method for sharing information and connecting with your audience(s).
Excellent manuals for making PDF files accessible. Includes exercise files!
Wrong type parameter supplied to a PDS procedure
You’ve meticulously tagged a PDF form using Acrobat X but when you run the Accessibility Full Check, you get this message.
Wrong type parameter supplied to a PDS procedure.
Check for form fields (usually tagged “FieldName - OBJR” by default) that have duplicate tags. One of them is the cause of the error. Delete one (or both) of them and retag the form field (annotation).
Googling this shows that this could happen for a few different reasons but they all have something to do with form fields.
Using that clue as a starting point I made a copy of my completed PDF and started the classic troubleshooting divide and conquer. Once I figured out that I only got the error message on page 2, I started deleting sections of tags on that page until I could get the check to run again.
Apparently it’s not enough to just delete one of the duplicates, you have to delete the correct one. That’s why it may be faster/easier to just delete both and retag that annotation.
We as an industry have to stop thinking that our job is making wrappers. Our job is not making templates. Our job is not making buckets that people can put stuff in. Our job is making an experience and that experience includes figuring out what the content is.
