Multiple Fetch Xml Statements with Or Filter in Portal Web Template

In a recent project, we had a requirement to display cases to the portal that are associated with either Contacts or Accounts. Our case entity had a related entity called Case Contacts, and our account entity had a related entity called Account Contacts. The account entity had a list of all the cases associated with the account.

Portals: Pass multiple parameters between Entity Forms

Recently we had the need to create multiple Entity forms in our portal, and be able to pass multiple parameters between the different pages of the portal. As it seems, you are able to pass a single parameter (such as the id of the created record) to the next form, but passing multiple does not seem to be the case. For this particular scenario, using Web Forms was not an option.
