[eclipselink-users] named query + skip null parameters

[Leon Derks <leon.derks@xxxxxxxxxx>]

Hello

I have a named query with three parameters.

These parameters are search parameters and can be null.

When I don't set the parameter in my DAO I get the following error: 
"Query argument productName not found in the list of parameters provided 
during query execution"

Is there a way to ignore the null parameters in my named query and only 
use the parameters that are not null?

Leon
