Hi,
I have a report builder application in my website.
On selecting the Report Builder,we get the report models.
On selecting on of the report models,i can add certain fields.
After adding the fields, i click on Filter button and add one more column which is a dropdown.
The problem i face is,after adding that column, I get the following error "The requested list could not be retrieved because the query
is not valid or a connection could not be made to the datasource" and drop down is not populated.


when i run d same query for in Query analyzer,data is retrieved in 10 secs,so it cannot be a time out problem....
I am not able to figure out exact problem.


Can anyone suggest me something for this.

Thanks.

Gunjan

post the query that failed if you want help.

We found that this error is similar to the deserialization error when you install the BI tool on the desktop. The first thing that we found that fixed the problem was to delete the user.dat file and have it recreated when the user logs on again; however, re-doing the user.dat file is not "painless" to the user.

Another way to fix it is to "enhance" the registry.

The first step is to add data to the HKCU\Control Panel\International\sPositiveSign field:

[HKEY_CURRENT_USER\Control Panel\International]
"sPositiveSign"="something"

then blank the field out

[HKEY_CURRENT_USER\Control Panel\International]
"sPositiveSign"=""

We created a batch file for the users to run.
