Ajaxing the Scripted Datasource [message #165879]

By the definition, scripted datasource treats Java classes as datasources
by itself. But BIRT report calls the Java class in a synchronous manner,
meaning that the report execution waits till scripted datasource completes
the execution. Is it possible to have AJAX feature here, where the report
calls the scripted datasource in an asynchronous manner, similar to web
application where the javascript code (using XMLHttpRequest) invokes a
Servlet asynchronously.

Thanks,
Ravi Chamarthy.

Ravi,

Nice thought, but often a second data set may depend on the first (via
nested tables) so this would still cause a blocking situation.
It might be a fun project to extent the Text Element to support something
here though.
