Difference between named where clause param and simple ui exposed bv

Question

Hi ppl,
I just had a small question ,
Assuming i have a view object with a named bind variable ( i give it at time of creation/definition itself ) ..
In order to set this, for some simple usage such as a list table , i believe there are two ways:-
1) in my managed bean , i could set the bind variable using the setNamedWhereClauseParameter
OR
2) i could expose the setter of my bind variable to the client interface and then set it manually
following either of the above , i would do a vo.executeQuery() ....
Are there any differences in the above approach ? which would be more appropriate ?

Hi,
except for that using a client method is less code to write because you don't have to get a handle to the VO first, I don't see a difference.
However, you can also create a binding in the pagedef fiel to the ExectuteWithParams operation on the ViewObject, in which case you could
- get a handle to the ExecuteWithParams binding (e.g. named "myHandlerToExecute")
- then do
myHandlerToExecute.getParamMap().put("bindVar Name", value);
myHandlerToExecute.execute();
Might be the smarter way and probably best practices too (for more details see the developer guide)
