p:fileDownload

[icordoba]

Hello,
it's only days I've embraced PrimeFaces and I am impressed with this library. Could not be happier!
Now a small problem I'm facing... I'm trying to use p:fileDownload in a p:dataTable to download one of files. I do the following:

Code: Select all

<p:commandButton title="#{msgs.download}" image="ui-icon-circle-arrow-s" action="#{afonicUserView.downloadAudio(box)}" ajax="false" immediate="true">
    <p:fileDownload value="#{afonicUserView.streamedContent}"/>
</p:commandButton>

The problem is that the getStreamedContent() is invoked before the downloadAudio() method, so I get an exception as the managed bean has not yet prepared the stream.
Can I make downloadAudio() method be invoked first? If not... what can be the approach to do the traditional "download" link in a dataTable?

thanks for any help,
Ignacio

Hi,

Welcome to PrimeFaces!

action is executed after actionListeners which fileDownload is so you need to use an actionListener to create your content;

Code: Select all

actionListener="#{afonicUserView.downloadAudio(box)}"

OOOps. Thanks a lot. Worked ok.

Ignacio, would you mind posting the Java and XHTML code that you used to get this working? I've been pulling my hair out trying to get fileDownload to work inside of a dataTable, and it looks like you have it solved. I created a thread on the issue but haven't had any responses so far: http://primefaces.prime.com.tr/forum/vi ... f=3&t=6547. I'd be much obliged if you have any help to offer.
