Set selected row in scrollableDataTable from bean

[artmooney]

Hello
It would be really great if anybody could give me a hint, how to display a scrollableDataTable with a specific row preselected from java code.

There shouldn't be any problem. Check scrollableTable example. There the example of simple selection anagement. You may set initial selection in the same maner.

Hi,
thanks for your reply in the richfaces forum. But I don't get this to work.

My table looks like this:

<rich:scrollableDataTable id="results" value="#{patientDetailsController.patient.actions}"
var="act" height="150px" status="commonstatus"
selection="#{patientDetailsController.selection}"
reRender="actionDetailsParent" sortMode="single"
binding="#{patientDetailsController.table}">

<a4j:support event="onselectionchange" reRender="resultsChildrenPanel, actionDetailsParent"
actionListener="#{patientDetailsController.takeSelection}"/>

I can access the selected rows after the user has selected them in the browser, but I don't manage to preselect e.g. the first row when the table is initially rendered. By the way what is this rowKeyVar attribute?

I tried

public HtmlScrollableDataTable getTable()
{
LogFactory.getLog(getClass()).info("getTable");
((SimpleSelection)table.getSelection()).addKey(0);

return table;
}

but this doesn't have any effect. Could you please give me some more hints. In the mentioned example I haven't found anything useful.

Regards,

Bernd

using demosite sample I've added

public DataTableScrollerBean() {
 selection.addKey(new SimpleRowKey(0));
 selection.addKey(new SimpleRowKey(1));
 selection.addKey(new SimpleRowKey(2));

 }

and my table looks like

 <rich:scrollableDataTable rowKeyVar="rkv" frozenColCount="1" height="400px"
 width="700px" id="carList" rows="40" columnClasses="col"
 value="#{dataTableScrollerBean.allCars}" var="category" selection="#{dataTableScrollerBean.selection}">

First three rows selected after initial page rendering.
