File upload async problems

[jmcollin92]

Hello,

I've got a basic form with a fileUpload in it. I want that the upload start when the user click on the submit button of the form.
So I've implemented that like this :

Code: Select all

<h:form id="fileTransfertView1UploadForm" prependId="false">	
 		<h:panelGrid columns="2">        
		    <h:outputLabel value="#{messages['file1']} :" for="fileTransfertView1UploadFormfile1"/>
                    <p:fileUpload widgetVar="widgetVar" id="fileTransfertView1UploadFormfile1" label="#{messages['file1']}:" fileUploadListener="#{fileTransfertTestControler.uploadFile1}" customUI="true"/>
 		</h:panelGrid>

        <p:commandButton id="fileTransfertView1UploadAction" value="#{messages['upload']}" action="#{fileTransfertTestControler.fileTransfertView1Upload}"
			onclick="widgetVar.upload();" ajax="true" update="messagesDialog, fileTransfertView1UploadForm"/>
</h:form>

This works well for small file but not with larger file because the action (#{fileTransfertTestControler.fileTransfertView1Upload} in this case) is fired before file upload is complete.

Is there a way to make the upload synchrone (ie : widgetVar.upload() returns when upload is complete) ?

Thank's for any help.

This looks tricky.

Why can't you move the logic of button action to the fileUploadListener and update="messagesDialog, fileTransfertView1UploadForm" to p:fileUpload.

Then you can upload the files with a button click using;

Code: Select all

<p:commandButton id="fileTransfertView1UploadAction" value="#{messages['upload']}" onclick="widgetVar.upload();return false;"/>

yes, in this very little it will work (and I appreciate the idea ...), but in a more real world, the button should also commit form input component.
In the best case, I would like the button to :
1. transfert file(s),
2. wait for files to be transfered (maybe it's possible in JS with ajaxStatus or something equivalent ?),
3. submit the form like usual.

If it is not possible out of the box, I will do totally differently.

Thank's anymay.
