ServerCustom validator: lookupStyle="factory"

[nicemoorthy]

Hi,

I am trying to implement a validator with lookupStyle="factory" to minimize object creation using "new". Am able to call factory class and struck up with passing value to it to identify which object need to be created.

I used very basic factory implementation.
1.V*Enum.java for validator types.
2.V*.java abstract class.
3.V*Factory.java calling class from ds.xml and return object for DMI. Use "create" method to return the object.

Some how i need to pass the value in V*Factory.java from *.ds.xml to identify which validator need to be picked.

Hi nicemoorthy,

did you see http://www.smartclient.com/smartgwte...ml#lookupStyle and the linked http://www.smartclient.com/smartgwte...iOverview.html?

In the 1st document it says:
Like the DMI methods, the create method can request a standard set of values as arguments. See DMI for a list of available values.

If you read the very end of the 2nd document, I'd say, that this signature should work: create(RPCRequest rpcRequest)
Can you get the values you need from the request? Is the method also executed with this signature (try setting a breakpoint).

I never tried this, but perhaps it will work.

Best regards,
Blama

Hi nicemoorthy,

sorry it didn't work. Let's see what Isomorphic says.
