Is it possible to create a business rule where I can set the value for a textbox with multiple lines. The text would be fixed inside the rule and would have multiple lines.
In the UI I have found that you can set the value as one-line text.
There is a workaround with javascript or a hidden field and default text in that field, but I am searching for a simple solution with only business rule.
You might be better using a workflow for this situation. You have a richer text editor where you can type in multiple lines.
Not sure how well the native controls of a business rule will support this (if at all).
