Using converters in non-JSF related code.

[Sean Schofield <se...@gmail.com>]

Has anyone ever used a JSF converter in code that wasn't specifically
related to JSF?  The reason why I am asking is that we are migrating
an application to JSF and a portion of the pages are in JSF but a
portion are still in Struts.

Two possible ideas come to mind:

1.) Use the converter's getAsString method inside of a static utility method

2.) Move the logic from the getAsString method to a static utility method.

I suppose approach #2 is less of a hack since you avoid FacesContext
and other JSF specific stuff in your static helper.

Any other thoughts or approaches?

TIA,

sean

There's not much in a converter and there shouldn't be any reason why
you couldn't do this.
However, since you're having to pass in a FacesContext and a
UIComponent, I think you'd have to reimplement a lot of unnecesary
support classes.

I'm not sure I'd stick it in a static utility method, but maybe that
makes sense in your use cases.

I'd probably go with a presentation-layer-independent converter class.
 Then subclass it to create the JSF converter.

When I look at my own JSF converters, this is a trivial refactoring. 
I've already got the non-JSF conversions being handled in separate
methods which are called by the getAs methods.
