I'm using Nintex Forms 22.214.171.124 in on-premise Sharepoint 2010
I have a form Hyperlink control connected to a column in a sharepoint list that is configured as display type "Image" (i.e. it will display the image that is at the URL address stored in the field)
I want to save the field with a value that I know will be initially be invalid. Initially it will only store the file name part of the URL, the address will be fixed-up in the background by a workflow after the item is saved. Trouble is the URL field is preventing my form from saving, because it keeps throwing up a "Please enter a valid web address" validation error.
As far as I can tell, Sharepoint itself has a pretty restrictive view of what a valid URL looks like, it won't accept just a fragment identifier like #MyFragmentID for example.
In the datasheet view of a list I can enter a URL of the form: http://#myfile.jpg in a hyperlink column
However, if I try to save this URL in a Nintex form I get the "Please enter a valid web address." validation error.
I want to disable the validation on this field to let me save the simplest URL form possible. I have tried setting up a validation rule that always returns false (no error), but the form still refuses to save a URL of the form shown above.
Any ideas on how to stop the Hyperlink field (apparently) doing extra validation over and above what Sharepoint itself allows?
