We have an HTML portlet that was working prior to 15.9.1, but does not work after upgrading.
The problem is related to using a "textarea" tag, and the placement of the closing tag.
For example this code might cause an issue:
<textarea name="abc" wrap="off" cols="100" rows="20" />
Release : 15.9.1
Component : CA PPM SAAS STUDIO
Adjust the code to include a specific closing tag section for textarea, which allows it to work. Here is an example:
<textarea name="abc" wrap="off" cols="100" rows="20"></textarea>
