I'm facing this problem as well: an issue is raised for every link or navigation action to internal page that does not have any data to send. Then I get an issue for "remember to fill out Data to send".
It happens in two instances so far:
1) In a workflow that specifies that under certain conditions (e.g., when page is loaded and a search for a thing is empty), the action is to send the user to an internal page, simple as that: no parameters, just a quick an easy link, which is why "data to send" is empty.
2) In a simple internal link that has the "data to send" field empty, even if it is sending more parameters to the page.
Would it be possible to either dismiss those alerts or to have a check box in the link interface and in the workflow navigation action that confirms that the link should NOT send any data, so the issue is not raised?
If I should raise a bug report, please let me know, and I'll gladly do it.
Thanks a lot in advance!
