             Summary: Consider optimizing the extendedDataModel re-generation for DataTable components
                 Key: RF-12685
                 URL: https://issues.jboss.org/browse/RF-12685
             Project: RichFaces
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: component-tables, optimization
    Affects Versions: 4.3.0.CR1
            Reporter: Brian Leathem
             Fix For: 5-Tracking


With RF-12673 we are triggering a re-generation of the extendedDataModel whenever the AbstractTableRenderer encodes a table component.

An optimisation would be to introduce triggers such that the extendedDataModel is only regenerated when required.  Marking the model as dirty for instance whenever the value of a relevant attribute is changed, and then only re-generating the model prior to render when the model is marked as dirty.

Prior to investing the time in resolving this issue, we need to measure the overall performance of the EDT to determine if this is indeed a rate-determining factor.  It may be that our time is better spent optimising other aspects of the DataTable component rendering.
