I've come across what appears to be a bug in SSRS Report Builder 2.0. Designing a parameter based report and deploying it is fine. However, when I reopen the report via Report Builder it's losing part of the parameter definition.
The report is very basic with a single parameter (datatype text,allow nulls,no default value). After deploying the valid report,reopening and executing I get...
The AllowBlank property of report parameter pName is false. However, the DefaultValue property contains a value that violates the AllowBlank property condition. (rsParameterValueNullOrBlank).
When looking into the 'Default Values' of the parameter, 'Specify Value' is now selected with a blank value. To correct this I have to select 'No default value' or (null) in the value.
Does anyone know of a fix\workaround for this?
