rich:fileupload upload button is disabled sometimes when page rendering

[babazs]

hy!

I use the rich:fileUpload component. When the page is rendering sometimes(10% of the cases) the upload button is disabled.

How can I solve my problem? Is it a bug?

thank you!

a snippet code will be helpful..

I use this component with a simple way:

<h:form id="myForm">

<rich:fileUpload    
            disabled="false"
            addControlLabel="#{messages['bt.lb']}"                                                      
            listWidth="300"
            listHeight="200"
            fileUploadListener="#{imageUploaderBean.imageUploaderMethod()}"
            id="uploader"
            maxFilesQuantity="100"
            immediateUpload="true"                                                     
            acceptedTypes="jpg,jpeg,gif,png"               
            autoclear="true"    
            allowFlash="true"                   
            >
            <a4j:support event="onuploadcomplete" limitToList="true" reRender="myForm"/>                   
            <f:facet name="label">
                      <h:outputText value="text" />
                  </f:facet>                   
        </rich:fileUpload>

</h:form>

flash plugin version could be the reason if you opening from  different PC's

[babazs]

thanks.

What does it mean: ' different PC's ' ?

[ilya_shaikovsky]

I believe that under "sometimes" you mean in some concrete browsers or at some client workstations only. So seems the problem with particular Flash plugin versions there.

thanks Ilya.

My enironment is: Windows Vista, Adobe flash 10,Firefox 3.6.3 latest.

I think it is an often used environment.

I think this not a flash plugin error, because I never meet this error  on the richfaces rich:fileupload demo page.

The only different from the demo page, is that I use a custom richfaces fileupload css

[ilya_shaikovsky]

do you able to reproduce that without flash enabled?

[babazs]

I went through to the richfaces document, and I found that maxFilesQuantity="1" , causes the problem, because It disable the button after fileupload.

But If I had multiple rich:fileUploader with maxFilesQuantity="100", and I upload 1 picture with the first rich:fileupload component, the second will be disabled, If I not reRender the second rich:fileupload.

I tested many times and I think <a4j:support event="onuploadcomplete" limitToList="true"  reRender="uploader"/>, solved the problem.

The only bug with this, that  when onuploadcomplete is occurred for 0.5sec the rich:fileupload buton will be disabled!!!(always) than normal.

So How can I avoid this effect If would like to use onuploadcomplete event to reRender?

thanks!
