Well I have started working as well as learning Dynamics 365 Portals. Seems like portals are quite interesting and bit tricky to play around. Lets move on to the scenario which I have faced.
My task is like to display a page in portal which contains account information. To achieve this I started creating a web page named “Account” which will use the entity form.
In Entity form I select account entity and account detail form to display the same on the portal. Now I am done with my changes and task as well. When I refreshed my portal to view the changes and account detail form, the portal does not show up. Indeed it throws up a weird error!!!!
I am dumbstruck, was not able to identify what actually went wrong. After some moment able to identify through error log which says like “Multiple Control ID’s in the entity form container“. Then I went to the entity form which uses the account detail form. The form actually contains field “Parent Account” which is used multiple times.
Portals does not allow to display multiple controls with same identifier in an entity form container. Hope this helps you. 🙂
