More than 255 characters in multiple lines of text?

Question

I have an InfoPath Form which submits the text of a textbox and saves it in a SharePoint list. Whenever a user types in more than 255 characters and I want to edit the element in the SharePoint list (e.g. change the value of a custom field) an error appears that the textbox cannot contain more than 255 characters.

It's weird because initially the column can contain more than 255 characters but as soon as I want to edit the element, I get this error.

My question is: How can I turn off the limitation OR how can I display a character counter next to my InfoPath textbox?

Thanks for your help

Answer 1

You have to check the "Allow unlimited length" checkbox on the list column's properties page.

Forget about InfoPath for a minute. Go directly into the SharePoint list settings and update the field properties. Take out the 255 limitation. Save your changes and then open a new InfoPath form and point it at the list. It will pick up all of your previous changes and as well, your field will not have this 255 length limitation.
