SelectItem and Converters

[Michael <mp...@gmail.com>]

Hi all,

I apologize if this question is answered elsewhere but I didn't have any 
luck with the mailing list archive, JIRA, or google.

I have an array of SelectItem objects with the value set to a Java 5 
enumeration. If I register a custom converter using converter-for-class, I'd 
expect to be able to bind the SelectItem array to a selectOneMenu and the 
converter would be called automatically.

Instead, my converter is never called. Further,
Application.createConverteris never called either (I set a breakpoint
there). I get the following
exception:
java.lang.IllegalArgumentException: Value is no String and component 
someClientId does not have a Converter

I looked at the code and it seems that
RendererUtils.getConvertedStringValuedoes not check to see if a class
converter exists. It only uses the
converter passed to it (which looking in HtmlRendererUtils, is the converter 
associated with the UIComponent).

I know there was some mention of this in MYFACES-131 but it was closed as a 
duplicate with no reference (at least that I could find) to the original 
bug.

Am I missing something or should this be filed as a bug?

Thanks,
Michael

Sorry about my ignorance.  What is "myfaces svn
snapshot"?

I'm using selectOneMenus with arrays of selectItems and converters
without any problem with a myfaces svn snapshot from 2005-08-16 (I'm a
couple weeks out of date because I had to work on a non-JSF project
for a bit).

It sounds like your converter isn't properly registered.
I think createConverter is only called after the appropriate converter
type to create is identified, so you really need to be setting a
breakpoint in the "findConverterToCreate" method (I don't remember the
name or location offhand, but if you start in UIInput, you should be
able to find it fairly quickly.  Alternately, you can just set a
breakpoing in UIInput.)
