File Download links on ADF pages

Question

Hi All, My requirement is to display no. of document links in pages. I am trying to use <af:fileDownloadActionListener> .
I am getting list of files/document while loading the page from backing bean and looping through it using <af:forEach>..
when i click on any link to download the document then fileDownloadBean.download function is called. So in backing function
download how i know which document user has clicked to download ? Any idea ?
<af:panelList id="pl1" clientComponent="true" >
<af:forEach var="file" items="#{fileDownloadBean.listFiles}" >
<af:commandLink text="#{file}" actionListener="#{fileDownloadBean.buttonClicked}" />
<af:commandLink text="#{file}" visible="false" id="cl2" actionListener="#{fileDownloadBean.buttonClicked}">
<af:fileDownloadActionListener filename="#{file}"
contentType="application/msword"
method="#{fileDownloadBean.download}" />
</af:commandLink>
</af:forEach>
</af:panelList>

Hi Tim, I tried to follow same step as mentioned in your blog..but getting y error no object found by id...
function customHandler(event){ 
var exportCmd = AdfPage.PAGE.findComponentByAbsoluteId("::cl2");
alert('hello');
var actionEvent = new AdfActionEvent(exportCmd);
actionEvent.forceFullSubmit();
actionEvent.noResponseExpected();
actionEvent.queue();
In my program commandlink is rendering by for each loop...i think in for each loop...iterating component does not assign proper ids...
<af:panelList id="pl1" clientComponent="true" >
<af:forEach var="file" items="#{fileDownloadBean.listFiles}" >
<af:commandLink text="#{file}" clientComponent="true" partialSubmit="true" actionListener="#{fileDownloadBean.buttonClicked}" />
<af:commandButton text="#{file}" id="cl2" visible="false" clientComponent="true" >
<af:fileDownloadActionListener filename="#{file}"
contentType="application/msword"
method="#{fileDownloadBean.download}" />
</af:commandButton>
</af:forEach>
</af:panelList>
I appreciate your help..
Thanks
