Hi, JSON plugin uses its own conversation mechanism, check JSONPopulator but I think it should be possible to inject XWorkConverter and use it to convert objects - this requires implementing your own JSONPopulator.
There is a task to do it so it should happen in Struts 2.5 ;-) https://issues.apache.org/jira/browse/WW-3364 Regards -- Łukasz + 48 606 323 122 http://www.lenart.org.pl/ 2016-12-01 20:07 GMT+01:00 Miguel Almeida <mig...@almeida.at>: > Imagine SearchAction{ > > private List<Record> evaluatedRecords; > } > > Record is an interface so to get auto-wiring to work you'd usually > set-up a > > SearchAction-conversion.properties: > KeyProperty_evaluatedRecords=id > Element_evaluatedRecords=com.bibliovigilance.model.RecordImpl > CreateIfNull_evaluatedRecords=true > > > I now want to create an Ajax post on this action.
