MyFaces UIData getDataModel() and getValue() interact with each other very differently from mojarra, apparently complicating the filtering implementation. Additional investigation is required.

With MyFaces, DataTable.getValue() is only called at the beginning of the Lifecycle, and not after filtering has been performed.

Implementing more of UIData similar to mojarra appears to work:

@Override
protected DataModel getDataModel() {

• Object value = this.getValue();

+ if (this.model != null)

+
// If existing tree check for changes or return cached model
if (hasTreeDataModel() || newTreeDataModel)

• return super.getDataModel();
  + Object current = getValue();
  + if (current == null) { + setDataModel(new ListDataModel(Collections.EMPTY_LIST)); + }

  else if (current instanceof DataModel)

  { + setDataModel((DataModel) current); + }

  else if (current instanceof List)

  { + setDataModel(new ListDataModel((List) current)); + }

  else if (Object[].class.isAssignableFrom(current.getClass()))

  { + setDataModel(new ArrayDataModel((Object[]) current)); + }

  else if (current instanceof ResultSet)

  { + setDataModel(new ResultSetDataModel((ResultSet) current)); +// }

  else if (current instanceof Result)

  { +// setDataModel(new ResultDataModel((Result) current)); + }

  else

  { + setDataModel(new ScalarDataModel(current)); + }

  +
  + return model;
  }

+ private DataModel model;
@Override
+ protected void setDataModel(DataModel dataModel)

+

This may introduce other side effects, however.

The update problem on the tabSetProxy page is now fixed. The h:messages was within a <div> but no ID was present, so the update would propagate out when the messages were dynamically modified. MyFaces does not wrap messages with an ID by default. (This case is complicated by the JavaScript state of the tab component – other components can typically handle a larger-than-necessary DOM update.)

There is a ticket for the h:message(s) issue with ICEfaces open in both our system (ICE-6622) and the MyFaces system (https://issues.apache.org/jira/browse/MYFACES-3272) but it doesn't appear that they plan to do anything about it so we'll likely still need to do something ourselves.

Marking as resolved. It looks like the remaining issues are general issues with the application or other areas and not specifically related to MyFaces. The following outstanding issues occur with both MyFaces and Mojarra.

Confirmation Dialog: Changing the Header or Message values results in double buttons being rendered until next edit.

Data Exporter: Specifying columns doesn't appear to work. Looks like Ant build may not include all necessary libraries.

Date Entry: Ajax Submit

Appears functional but logs this to the server console the first time Ajax Submit is selected (depending on JSF implementation)

Drag Drop: Turning on Clone Helper mode appears to do some strange things.

Notification Panel: The state of the button does not revert from "Hide" back to "Show" if you close the panel using the close icon.

Slider: Asynchronous doesn't work. Setting options can cause slider rail to disappear.
