901166 - Trying to Print Preview XUL documents should give a better error message

Status: RESOLVED INVALID

(Toolkit :: Printing, defect)

Description

[Dan Wolff]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:24.0) Gecko/20130802 Firefox/24.0 (Nightly/Aurora)
Build ID: 20130802004004

Steps to reproduce:

1. Go to a new tab (about:newtab is a XUL document)
2. Go to print preview (Aurora->Print...->Print preview or File->Print preview)


Actual results:

After half a second of processing something, a dialog 'Print Preview Error' appears with the message 'There was an unexpected problem while printing.'.


Expected results:

The error message should instead be 'Printing XUL documents is not supported.', just like when trying to *print* a XUL document.

And just like with 'Print...', the error message should be instant.

Seems to me we should just disable the Print/Print Preview commands
for XUL documents since we don't support that.

In the menus you can do that, but it *is* nice to get an error message when pressing Ctrl+P.
