Curtiss Howard updated MYFACES-1811:
------------------------------------
Status: Patch Available (was: Open)
> cannot set enctype on h:form with el
> ------------------------------------
>
> Key: MYFACES-1811
> URL: https://issues.apache.org/jira/browse/MYFACES-1811
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-252
> Affects Versions: 1.2.2
> Environment: Windows, Tomcat 6.0.14, facelets 1.1.14
> Reporter: John Singleton
> Priority: Critical
>
> I have the following code in a facelets composition
> <h:form onsubmit="return submitForm()" id="main" enctype="#{(empty
> encoding) ? 'application/x-www-form-urlencoded' : encoding}">
> Depending on how the form is used the enctype might need to be
> "multipart/form-data"
> I use the composition like so:
> <ui:decorate xmlns="http://www.w3.org/1999/xhtml";
> xmlns:t="http://myfaces.apache.org/tomahawk";
> xmlns:ui="http://java.sun.com/jsf/facelets";
> xmlns:h="http://java.sun.com/jsf/html";
> xmlns:f="http://java.sun.com/jsf/core";
> template="#{pqfn:absoluteStyle('homeTemplate.xhtml')}">
> <ui:param name="encoding" value="multipart/form-data" />
> This worked prior to MyFaces 1.2. It doesn't work in 1.2+ Looking at
> HtmlForm.java :
> // Property: enctype
> private String _enctype = "application/x-www-form-urlencoded";
> /**
> * Gets The content type used to submit this form to the server.
> *
> * @return the new enctype value
> */
> public String getEnctype()
> {
> if (_enctype != null)
> {
> return _enctype;
> }
> ValueExpression expression = getValueExpression("enctype");
> if (expression != null)
> {
> return (String)expression.getValue(getFacesContext().getELContext());
> }
> return "application/x-www-form-urlencoded";
> }
> As enctype is initialized in it's declaration it is never null. Therefore the
> ValueExpression is never evaluated. This means the enctype cannot be set
> using an EL Expression in the page.
> I'm not sure if this is a bug against HtmlForm, or the maven-faces-plugin
> that is generating this class.
