Report is unavailable or session has expired message when Exporting

[Mark DeMichele]

Hi,
If a user leaves the web report viewer preview screen open for a long period of time and attempts to export to CSV, the resultant screen is blank with a title of "Error" in FF 3.6.8 and IE7. To see the error, you have to do a View Source.

1. Is there any way to have the message appear explicitly rather than doing a View Source? I'm guessing this is some sort of MIME type issue? 

2. Can the message be customized in any way? Unfortunately, even the suggested advice to refresh the page doesn't work. A user would have to go back to the preview screen using the browser back button, then refresh the page. It's just a bit stigmatizing for users to simply see a blank screen.

Thanks.

Hi Mark DeMichele,

Unfortunately this is a bug that slipped into the Q2 release and it is logged in our system for fixing. We would do our best to address this for a subsequent internal release or service pack. If this is a major showstopper for your application and you cannot wait for a fix, you can use a timer to make requests to the page, so that the session does not expire.

Please excuse us for the temporary inconvenience.

Greetings,
Steve

Hi Steve,

I appreciate the heads up. We can wait for the fix. In the meantime, I'll attempt the timer workaround.

Thanks!
