Hi,

I am using Telerik Reporting Q2 2009, and a bug was discovered with the date parameters.  I have two of them: Start Date and End Date, both allow nulls.

To recreate the issue, I uncheck the Null checkbox on one, click the "Go to the next month" link a few times, uncheck the Null checkbox on the other, click the "Go to the next month" link once, and I receive a System Error.  Note that I did not select a date from the first date selection.  With the calendar still open, I clicked the Null checkbox on the next date selection.

This is most reliably recreated in Safari 3

Hello Jeremy,

We have tried to reproduce this on browsers other than Safari with no luck. On Safari 4 we've managed to encounter it after quick clicking on the calendar dates and clicking preview while Safari still shows loading at the address area.
The calendar control used in the report parameters' area is the standard MS asp:calendar control, so the same issue can be replicated in a simpler scenario where the chosen date is filled in an input value and on a button click this value is increased/decreased by a day. So it would seem like a Safari issue when clicking a bit too fast.
If you can provide us with a sample project and step by step instructions on how to replicate this reliably on other browsers, we would gladly review it and take the time to address such an issue.

All the best,
Steve
