[jboss-user] [JBoss Seam] - Please Help (multiple row operations in a data table)

[ask4saif]

Dear fellows,

the problem is i want to perform multiple row deletion in a datatable. here is my code, it is the exact copy of the code given in the dvd example.


  | <h:dataTable id="hotelslist" rows="5" value="#{allHotelsList}" var="hotels" styleClass="scrollerTable" headerClass="standardTable_Header" footerClass="standardTable_Header"  columnClasses="column_style,column_style,columna_style1" >					
  | <h:column>
  |              <f:facet name="header">
  |              <h:outputText value="Select" />
  |              </f:facet>
  |              <h:selectBooleanCheckbox value="#{hotelSelections[hotels]}" />
  | </h:column>
  | 
  | <h:column>
  | 		<f:facet name="header">
  | 		<h:outputText value="Name"/>
  | 		</f:facet>
  | 		<h:outputText value="#{hotels.name}"/>
  | </h:column>
  | 										
  | <h:column>
  | 		<f:facet name="header">
  | 		<h:outputText value="City"/>
  | 		</f:facet>
  | 		<h:outputText value="#{hotels.city}"/>
  | </h:column>
  | 										
  | <h:column>
  | 		<f:facet name="header">
  | 		<h:outputText value="Contact Number"/>
  | 		</f:facet>
  | 		<h:outputText value="#{hotels.phone}"/>
  | </h:column>
  | 										
  | <h:column>
  | 		<f:facet name="header">
  | 		<h:outputText value="Action" />
  | 		</f:facet>
  | 		<h:commandButton value="Details" action="#{HotelsAction.showHotelDetails}" image="../images/details.gif" /> 
  | 
  | </h:dataTable>
  | 						
  | 
  | <h:commandButton action="#{ERegHotelsAction.deleteAll}" value="DeleteAll"/>
  | 

In the above mentioned code, whenever i press any command button the associated action is not called by the component and the same page is redisplayed.

and if i remove the "[hotels]" EL exp from the checkbox value then it start working. I dont know what is going on, and what is the exact problem. 

can anyone help me on this matter.

thanks alot in advance
