OperationBinding in multiple XML Datasources

[miguialberto]

Hi!

I am using SmartGWT EE 3.0p

I have defined in a XML datasource an operation to perform a "Group By" in server:

<DataSource..
...
<operationBindings>
		<operationBinding operationType="fetch" operationId="groupOp">
			<selectClause>$rawValue.criteria.myProp</selectClause>
			<groupClause>$rawValue.criteria.myProp</groupClause>
		</operationBinding>
</operationBindings>
...
</DataSource>

I use it for several fields, so I did it like a template.
Before call this operation, I set in Criteria which field name I want to group ($rawValue.criteria.myProp). It works fine.

My problem is that I would like to use this fetch operation in all my XML datasources and I don't know how. I have read the docu and threads but I don't really know how to make an operationBinding available for many DS.

There is a way to inherit not only fields but also operations between two XML?
I need maybe to think in another strategy (DMI?)?

Thanks in advance!

Ok, I am trying to put this function in server by extending "IDACall", but I have not found already a good solution...
Any help?
