How Can I use EL in JSF

Actually By Problem Is Regarding DataTable Binding Method

<f:subview id="vesselist" rendered="#{vesselBaseVO.dfsVO.dfsData.dfsResultBeanListSize>0}" >

<t:dataTable value="#{vesselBaseVO.dfsVO.dfsData.dfsResultBeanList}"

sortable="false"

var="result"

id="dfsTable"

forceId="true"

rowClasses="AlternateRow1, AlternateRow2"

columnClasses="TableColumnText, TableColumnText, TableColumnText, TableColumnText, TableColumnText, TableColumnText, TableColumnText, TableColumnNumber, TableColumnNumber, TableColumnText"

headerClass="TableHeader"

frame="box"

width="100%"

preserveDataModel="false"

rows="10" binding="#{vesselBackingBean.searchResultDataTable}" rendered="true">

</t:dataTable>

</f:subview>

Although I had block it with renderer attribute ,

DataTable would not show if resultList size is 0 but

DATA Table binding method is still called even dataTable is not rendered on page I want to block that binding method calling ...

How can I do that !!!!

Even if the rendered attribute is false, the component still exists within the view and it is entirely proper for the JSF implementation to invoke your binding. In fact, the managed bean could manipulate the rendered attribute of the data table after the binding is invoked.

It seems to be that it shouldn't be too hard to modify your code to handle the fact that the binding method will always be called.
