[jira] Updated: (TAPESTRY-2453) Form enctype is not updated when an Upload component is injected via FormInjector / AjaxFormLoop

Howard M. Lewis Ship updated TAPESTRY-2453:
-------------------------------------------

    Priority: Minor  (was: Major)

The workaround is to ensure that the Form is always using the multipart encoding type (even if it does not contain a file upload).  This could be accomplished with a simple mixin to the form.  Dynamically managing the enctype on the client-side is possible in theory, but would be a bit on the unwieldy side.

>          Issue Type: Bug
>          Components: tapestry-core
>    Affects Versions: 5.0.13

> The following snipped describes the situation:
>     <t:form>
>       <ul>
>         <li t:id="loop" t:type="AjaxFormLoop" source="uploads" value="currentValue"  encoder="encoder">
>           <t:submitnotifier>
>                 <t:upload value="currentValue.uploadedFile" />
>             <t:removerowlink>remove</t:removerowlink>
>           </t:submitnotifier>
>           <t:parameter name="addRow">
>             <t:addrowlink>Add a row</t:addrowlink>
>           </t:parameter>
>         </li>
>       </ul>
>      <t:submit>Submit</t:submit>
>     </t:form>
> Adding a row to this form causes an addition of a Upload component. However when doing so the enctype of the form tag should be updated to "multipart/form-data". However this does not happen. I suppose that reverting the enctype back to normal when the last upload component is removed doesn't happen too.
