Rajeev Pentyala – Microsoft Power Platform

Recently we encountered a strange issue in our Dynamics Portal SaaS variant.

We got a requirement to allow Portal users to create ‘Custom Activity’ records from Portal.

To achieve this, we created an Entity form for the Custom Activity with mode set to ‘Insert’ and configured Web Template.

Issue:

• After configuring Entity Form, Page Template and Web Template, we could not save the record from Portal.
• Up on ‘Submit’ button click on Create form, there was no server post back.
• On browser console, “Unable to set property ‘isvalid’ of undefined or null reference” exception has been logged.

Reason and Fix:

• Issue was due to the additional character in ‘Web Template’ Source HTML content (refer below highlighted) and correcting the HTML fixed the issue.
