Daniel Pitts updated OGNL-19:
-----------------------------
Issue Type: New Feature (was: Wish)
> Ability to programatically "step" through an Ognl execution.
> ------------------------------------------------------------
>
> Key: OGNL-19
> URL: https://issues.apache.org/jira/browse/OGNL-19
> Project: OGNL
> Issue Type: New Feature
> Environment: All.
> Reporter: Daniel Pitts
> Labels: feature, runtime
>
> First, let me describe in abstract terms my use case:
> I have several "resources" which I need to retrieve (by URI). I'm using Ognl
> to describe the URI of these resources.
> Some of the resource URI's might be dependent on content in other resources.
> I'd like to be able to set up my own queuing mechanism which will put on hold
> any such dependent URI until the resource is retrieved.
> Right now, the Ognl expression is evaluated using the Java stack, which makes
> it extremely difficult to "pause" an expression.
> It would be nice if the expression state could be externalized and run
> iteratively instead of recursively.
