DataSource ready delegate / PoolParam

[jonmifsud]

I'd have a small feature request; sometimes I'd like to output parameters from a remote datasource. I fully understand that outputting the right parameter might involve a lot of xPath computations etc. But it would be an interesting feature.

Anyway at the least would be interesting if we could have a delegate to plug into - and then let the extension developers worry about how to 'grab' the right output parameters for their need(s).

Not expecting anything immediate but would be interesting to have a healthy discussion this way one avoids 'custom' datasources where possible so when upgrading one does not risk incompatibility.

There is a DataSourcePostExecute that is new in 2.3 that will allow you to do this.

Oh.. must have missed this! Started working before the official docs were out.

However would PoolParam output through xPath make sense to implement or possibly too complex?

[brendo]

It's an interesting concept and it'd be exciting to see what extensions can do to implement it. I don't think it'd be overly complex, a duplicator like the one in Global Parameter Loader is one type of interface that would allow an arbitrary amount of parameters to be created

Closing this issue because extensions can already use the existing delegate.
