Phanidhar Adusumilli commented on TOMAHAWK-548:
-----------------------------------------------
Since UIData supports value binding for the attribute "first" (getFirst is
using it), Can we have setFirst push it to the valuebinding (if the
valuebinding is present)?
In the current implementation setFirst only stores it locally thus makes the
value binding useless.
By making setFirst to support pushing of the value to the value binding, one
would have a mechanism to reset this value. i.e. when the datamodel is updated
in the managed bean it can also modify the attribute used for value binding.
This does not eliminate the java code, but does not require the table component
binding to the managed bean.

> URL: https://issues.apache.org/jira/browse/TOMAHAWK-548
> Project: MyFaces Tomahawk
> Issue Type: Improvement
> Components: Data Scroller, Extended Datatable
> Reporter: Mike Kienenberger
>
> There should be a way to reset the datascroller back to page one when
> clicking a UICommand without writing java code and binding the UIData to the
> backing bean.
> Currently this has to be done as follows:
> <h:commandButton
> value="Submit Query"
> action="#{searchPageBean.search}"
> actionListener="#{searchPageBean.resetDataScroller}">
>
> </h:commandButton>
> <t:dataTable id="searchResultsDataTable"
> binding="#{searchPageBean.searchUIData}"
> public void resetDataScroller(ActionEvent e)
> {
> searchUIData.setFirst(0);
> }
