Parameter default not updating on deploy

I've got an issue with a report of mine where the default parameter isn't being cleared. Let me explain...

I created a report with a parameter on it. While I'm working on the cosmetics of the report, I didn't want to have to keep typing in a value just to see it run, so I set the default value on the parameter. I finish the report and deploy it and everything is ok. Then when I go to the page to view it, I notice that the default is still there, so I go back and edit my report to take out the default and just use NULL. In the preview tab, it looks ok, so I deploy the report again. Now when I go to the report, it still has the default value in the parameter box.

Does anyone have any idea as to why this is happening? The only way I could get around it is to drop the parameter from the report, deploy it, then re-add the parameter and deploy it again.

Thanks in advance,

Jarret

Parameter Change and Report Clears

When I change the value of a parameter the report is cleared on a post back to the server and I have to click on the View Report button to see any results. Is there a way to either not post back to the server when the parameter is changed or automatically post back and retrieve the new results?

I found this link below here and it sounds like I am out of luck since both of my parameters are dates with functions to define them. I have tried changing their order with no luck.

Does anyone know if this is an issue without a work around?

Thanks!

Looks like I am out of luck.
