SequenceDataModel.walk(...) Fires DataModelEvent for Each row instead of a only 1! ---------------------------------------------------------------------------------- Key: RF-4798 URL: https://jira.jboss.org/jira/browse/RF-4798 Project: RichFaces Issue Type: Bug Affects Versions: 3.2.2 Environment: Ajax4jsf in RichFaces 3.2.1 & 3.2.2 bundles. Reporter: Paul Kossler org.ajax4jsf.model.SequenceDataModel.walk(...) ... while (rows < 0 || currentRow < rows) { wrappedModel.setRowIndex(currentRow); if(wrappedModel.isRowAvailable()){ visitor.process(context, new Integer(currentRow), argument); } else { break; } currentRow++; } ... Issue: wrappedModel.setRowIndex(currentRow) fires a DataModelEvent for each row in the wrapped model. This creates broken behavior for the Event model. If you have a listener on a DataModel it gets called for each and every row during PhaseId.APPLY_REQUEST_VALUES This makes the model think every row gets selected for each cycle! NOTE: The org.richfaces.model.SequenceDataModel.walk is implemented with out this. Its seems to me that the latter model handles this the general wrappedData access issue cleanly by copying the Collection ObjectReferences into an iterable list.
