description:
error message is not correct after delete the report parameter linked to the data set.

build number:
2.5.2.v20100209-1429

steps to reproduce:
1. new a report parameter.
2. new a sample data set with parameter, link the data set parameter to the report parameter.
3. delete the report parameter and open the edit data set dialogue, go to "parameters" tab, check the error message.

expected result:
"param_1" is shown instead of "{1}".

actual result:
"linked report parameter "newparameter" of the data set parameter "{1}" does not exist now." is shown (see the screenshot).

error log:
n/a
this bug has been fixed.
"linked report parameter "newparameter" of the data set parameter "param_1" does not exist now" is shown.
