How to get selected rows?

Hi, I am new to RichFaces, I have a beginner question here.

I have a search result for 100 records shown in 10 pages. I select some on page 1, 2 and 3 by checking the checkbox. How can I get the selected rows in back bean?

Thank you for help!!

<rich:simpleTogglePanel label="Schools" immediate="true" switchType="client">
 <tr:panelFormLayout rows="1">
 <tr:inputText label="School Name:" value="#{searchCriteria.name}"/>
 <f:facet name="footer">
 <tr:panelButtonBar>
 <tr:commandButton text="Search Schools" action="#{schoolQuery.initialSearch}" blocking="true"/>
 </tr:panelButtonBar>
 </f:facet>
 </tr:panelFormLayout>
</rich:simpleTogglePanel>

<rich:dataTable id="schoolTable" value="#{schoolQuery.richModel}" var="item" rows="10" width="100%" frame="box">
 <f:facet name="header">
 <rich:datascroller for="schoolTable" renderIfSinglePage="false" binding="#{jsfBinding.datascroller}" ajaxSingle="false"/>
 </f:facet>
 <rich:column>
 <f:facet name="header">Name</f:facet>
 <h:outputText value="#{item.name}"/>
 </rich:column>
 <rich:column>
 <f:facet name="header">Select</f:facet>
 <tr:selectBooleanCheckbox value="#{item.selected}"/>
 </rich:column>
</rich:dataTable>

I used a binding to a UIData object e.g. schoolTableData)

something like:

<rich:dataTable id="schoolTable" binding="#{yourBean.schoolTableData}" ...


In your controller bean:

 UIData table = yourBean.getSchoolTableData();
 for (int rowIndex = 0; rowIndex < table.getRowCount(); rowIndex++) {
 // Select the a row (if there is one)
 table.setRowIndex(rowIndex++);

 SchoolQuery schoolQuery= (SchoolQuery) table.getRowData();
 if (schoolQuery == null) return null;

 //check only the selected entries
 if(!schoolQuery.isSelected())
 continue;
