I am looking at the ComponentHandler.java from Facelets 1.1.14 and I
see no meta rules for converter. This means that converter="#{}" would
be set without any type of special handling. So:
<my:component value="foo" converter="contentConverter" />
Is definitely nod valid syntax. The converter must evaluate to a
converter instance, not a converter ID:
public void setConverter(Converter converter) {...}
So you have to use EL:
<my:component value="foo" converter="#{bean_that_implements_converter}" />
I do not know why this doesn't work though:
<f:converter converterId="contentConverter"/>
That is handled by com.sun.facelets.tag.jsf.ConvertHandler
The only requirement is that the parent component of the tag must
implement ValueHolder, which UIOutput does.
It creates the converter using:
return ctx.getFacesContext().getApplication().createConverter(this.converterId);
If you are using facelets 1.1.14 and have verified your taglib.xml
files are correct, then I would advise you to debug into the facelets
code for the classes that I have mentioned and see what is going on
first hand.
You can also try calling this manually from a bean somewhere and
making sure it works:
FacesContext.getCurrentInstance().getApplication().createConverter("contentConverter");
