I'm running a Plone 22.214.171.124 installation with Plone Formgen 1.7.12 and the October 2015 hotfix installed.
I've used Custom Script adapters to successfully create News Items and Events.
Now I'm trying to use a Custom Script Adapter to create a Link item and am successful, EXCEPT - the destination portion of the URL is stripped, leaving only the "http://" part of the URL. This is the case whether using the String Field or Text Field PFG fields. I presume this is HTML filtering but can't find where to adjust it. HTML filtering options in the Control Panel don't seem relevant. Thanks in advance.
For the uninitiated, and those without access to Plone core on github, you can find this folder in your Plone 4.x filesystem under buildout-cache/eggs/Products.ATContentTypes-etc. It is the same in Plone 5 because P5 continues support for Archetypes. I haven't tried to find the Dexterity-based version.
For coders these are trivial questions - this reference is for those without that expertise.
