Description of problem:
When trying to preview a report, user input is handled incorrectly. Its value is probably not passed or plainly wrong. In default templates, this leads to empty dataset. When I remove the search from the default template, preview shows full dataset. When generating report normally, user input works.
Version-Release number of selected component (if applicable):
Reproduced on Sat 6.5 snap 3
Steps to Reproduce:
1. Monitoring -> Report Templates -> <some_default_template> -> Preview
Dataset for the selected host
As described in inputs help, if input is not ready, it's replaced with "$USER_INPUT['name']" string. Of course that's not a valid syntax for searching. This is limitation known from older Satellite versions, I'd suggest turning this into RFE for "allowing specify custom values for user inputs when previewing template" or "define sample preview value at input definition" based on what you'd prefer as a solution.
Does this mean preview won't work for most of the templates using user input?
Preview works, but if the user input is used the way all our default templates use it - for searching the records - the result will always be empty. But I understand, the fact you're seeing empty result for preview is not very useful. We could disable the preview for 6.5, but that would probably be worse. After short conversation on IRC, it seems for 6.5 it would be reasonable to use empty string as a value in preview. We need to check whether it will be compatible with REX templates.
