SSRS report discard selected value

Question

I have SSRS 2012. When I load report page url, select all parameters values and hit button "view report", all my parameters discarded to blank and nothing happens. Report is not rendered. And web page is looks like I just load it.

But if I load project with this report to the Visual Studio and run report from there all is fine.

I have been searched the web, but with no luck. Please help.

Update

Microsoft SQL Server 2012 (SP1) - 11.0.3368.0 (X64) on Windows NT 6.2 (Build 9200)

Answer 1

After all checks and researches I think we have this issue: http://support.microsoft.com/kb/2863256

Answer 2

My first thought: Are there any inter-dependencies between your parameters that might be causing a failure when an invalid combination is selected?

Added

There are several other things to check:

1. Whenever you have more than one parameter, the second parameter is treated as dependent on the first. Therefore, if there is any issue with the first parameter, the second parameter will fail (and empty/disable itself). Look to number 2 as tp why your first parameter could fail and cause a domino effect on the other parameter(s).

2. I found this blog discussing that non-printable characters can cause failures in SSRS 2005, and I found some other sites suggesting the issue may persist in later versions as well. If this is the problem, you'll have to remove the characters before you can continue. See this site as a starting point.

3. Double-check how you assign default values to the parameters. I haven't seen this happen with two parameters, but if you have three and the second is missing a default value and the third isn't, it can cause problems.

Hope this helps.
