Now there is. I just checked in a FlowAttributeModule and a FlowContinuationModule in the scratchpad block. Booth are JXPath enabled.
>I just checked the cocoon.xconf and found there a declared JXPathMetaModule under the name "jxpath"
which lead me to believe something along the lines of <map:parameter name="cont-id" value="{jxpath:$continuation/id}" /> would do it
but that doesn't seem to work :-(
delving in the code none of the modules seem to make the classic flow parameters available (e.g. for comparison jxtemplate knows about $continuation, $request, $session IIRC)
but maybe my understanding of modules is wrong to even expect this?
Per se the JXPath module is not connected to flow or JXTemplate but applies XPath expressions to objects using the JXPath library. However,
if we feel like there should be a module that makes FOM available, this
should be an easy task to do. Perhaps this should be called "FlowObjectModelInputModule" resp. "fom" and inherit from the AbstractJXPathInputModule.
If we put request, session, continuation etc as variables within the JXPathMetaModule, it would replace the functionality of the current input modules. But IMO it would do it in a clumsier and more monolitic way. I prefer keeping modules simple and with well defined and limited scope.
