dataExporter inside composite component

[peter]

Hi! I want to use p:dataExporter inside of composite component. Component shows fine in using page but when i click on commandLink to export the data it gives me error "Cannot find component "billsTable" in view.". dataExporter can not reach the dataTable component in using page. How to solve this? Below is my jsf code:
Composite Component

Code: Select all

 <cc:interface displayName="data Export table"
                expert="false"
                preferred="true"
                name="dataExportTable" >
      <cc:attribute name="dataTableId"
			displayName="Data table id"
			required="true"
			type="java.lang.String" />
      <cc:attribute name="pdfEncoding"
			displayName="Encoding of exported pdf file, for ex. Cp1250"
                       required="false"
                       default="UTF-8"
		       type="java.lang.String" />
  </cc:interface>

  <cc:implementation>
      <table cellpadding="2px;">
	 <tr>
            <td>
		<h:commandLink title="#{msg.export_to_excell}" >
			<p:dataExporter type="xls"
                                                 target="#{cc.attrs.dataTableId}"
						fileName="#{msg.bills_export_file_name}" />
			      <h:graphicImage value="#{resource['images:exportExcell.png']}"
							style="border-style: none;" />
		</h:commandLink>
	     </td>
          </tr>
    </table>
  </cc:implementation>

Using page

Code: Select all

<p:dataTable id="billsTable" ... >
...
</p:dataTable>
<ez:exportTable dataTableId="billsTable"
                         pdfEncoding="Cp1250"/>

I'm using mojarra 2.0 jsf implementation with tomcat 6.0.20 and latest primefaces snapshot 2.0.1 (downloaded on 16th april).

I'm not sure why it cant find it, can you try giving the client id of datatable, also please provide the full page source, maybe we are missing something.

FYI DataExporter is calling UIComponent.findComponent api. See;

http://java.sun.com/javaee/javaserverfa ... ng.String)

[peter]

Problem solved! After reading javadoc for findComponent, i found a solution. Target attribute for dataExporter has to start with separator character, which is ':'. With ':' at the beginning, findComponent looks for component in jsf page, and without it, findComponent starts searching in composite component.
Thanks for help Cagatay!

[peter]

And one important thing - one also has to include form id before dataTable id , even if from has prependId="false", so target should looks like: target=":myForm:myDataTable" .

                                  #{user.login}
                               </p:commandLink>

		                   </p:column>
		               </p:dataTable>

When i look the source code i have this :

Code: Select all

<div id="j_idt33:j_idt84:pdtUserSearch" class="ui-datatable ui-widget">

Any idea about this problem ?

Thanks
