Within the option “Open URL” in the End user interactions part of a workflow, I defined a URL consisting of a base URL and two URL params: recordID and a value to be used as a default value in the custom form of the page.
When opening this URL in a new tab, both params work correctly: The recordID to identify the associated record and displaying information in a list detail section. The title is being used as a default value in a custom form on this page.
But when I try to open the same page with the same URL in a modal, the title param is not being used as the default value of the above mentioned field.
