Help : how to transfer data from a rich:datatable row to a managed bean after a rowdblclick

[ayoubtunu]

Hi every body,

I was looking a long time ago for somebody who had an experience on richfaces4 components especially in rich:datatable and it's related attributes and events. i'm really disturbed and tired from searching on the internet without any satisfying result.

Well, I want to get data from a rich:datatable row after it's been clicked twice and send it to a managed bean to display it on another JSF screen (like an screen details).

Here's the my source code :

<a4j:jsFunction name="showRowDetails" >

                        <a4j:param name="rowKey" assignTo="#{currencyBean.showRowDetails}" />

</a4j:jsFunction>

<rich:dataScroller for="table" maxPages="10" renderIfSinglePage="false"/>

<rich:dataTable value="#{currencyBean.listeCurrency}" var="carrency" id="table" rows="11" rowClasses="row1,row2" onRowDblClick="showRowDetails({carrency.currency_code})">

  <h:column>

                                                  <f:facet name="header">

                                                      <h:outputText>Currency code</h:outputText>

                                                  </f:facet>

                                                  <h:outputText value="#{carrency.currency_code}"></h:outputText>

                                            </h:column>

                                            <h:column>

                                                  <f:facet name="header">

                                                      <h:outputText>Abreviation</h:outputText>

                                                  </f:facet>

                                                  <h:outputText value="#{carrency.currency_code_alpha}"></h:outputText>

                                            </h:column>

                                            <h:column>

                                                  <f:facet name="header">

                                                      <h:outputText>Wording</h:outputText>

                                                  </f:facet>

                                                  <h:outputText value="#{carrency.currency_name}"></h:outputText>

                                            </h:column>

</rich:dataTable>    

<rich:dataScroller for="table" maxPages="10" />

Here's my ManagedBean's method "currencyBean.showRowDetails" :

	public String showRowDetails(String codeCurrency)
	{
		currency_tableService = SpringUtil.getCurrencyService();
		try {
			listeCurrency = currency_tableService.searchCurrency_tableService(
					ServiceContextStore.get(), this.getCurrencyTable());
		} catch (Exception e) {
			e.printStackTrace();
		}
		this.getCurrencyTable().setCurrency_code(null);
		return "show_row_details";
	}

When i deploy my projet in tomcat7 server and i run the browser every thing work as expected despite the rowdblclick event which give nothing !!

I still waiting for ur replies, help me pleaaase Many thanks in advance.
