I am using the fileUpload feature of PrimeFaces 4.0 to upload a .css file. The application then needs to load all of the stylesheet classes in the file. The application then should render a selectOneMenu with the classes, one of which the user will choose, which will then apply to another element.

The problem is that I could not find a way to update the selectOneMenu after having uploaded a file. I have the file upload even longer as loading the elements from selectOneMenu ManageBean.

Here is upload.xhtml:

<h:form id="Edit" enctype="multipart/form-data">
<p:fileUpload fileUploadListener="#{sintaxisWizard.handleFileUpload}"
    mode="advanced" 
    update="growl productCode" 
    label="Escoge archivo css" 
    auto="true"
    sizeLimit="10485760" 
    allowTypes="/(\.|\/)(css)$/" 
    invalidSizeMessage="El maximo tamaño del archivo es 10 Megabytes !"
    invalidFileMessage="Unicamente se puede subir archivos css" />
</h:form>

And my selectOneMenu

<p:selectOneMenu id="combo" value="#{sintaxisWizard.animalSelected}">
    <f:selectItem itemLabel="Select..."  noSelectionOption="true"/>
    <f:selectItems value="#{sintaxisWizard.allAnimals}" />
</p:selectOneMenu>

Si necesitas una traducción al español, y te lo proveeré.

You will need to set the update component of your p:fileUpload to actually update the correct component. Right now, it is set to update growl and productCode, but not combo, the ID of your p:selectOneMenu.

None of this deals with the problems you will face in dynamically loading a new CSS page for the user, which will be quite difficult (although technically possible).
