[OT] PropertyEditor
I have a custom tag in which I am evaluating an attribute as follow:
(Locale)ExpressionEvaluatorManager.evaluate("locale", expr,
Locale.class, this, pageContext)
But I get an error:
javax.servlet.jsp.JspException: An error occurred while evaluating
custom action attribute "locale" with value "en_US": Attempt to convert
String "en_US" to type "java.util.Locale", but there is no
PropertyEditor for that type (null)
at org.apache.taglibs.standard.lang.jstl.Evaluator.evaluate(Unknown
Source)
at org.apache.taglibs.standard.lang.jstl.Evaluator.evaluate(Unknown
Source)
at
org.apache.taglibs.standard.lang.support.ExpressionEvaluatorManager.evaluate(Unknown
Source)
I am using standard.jar (v 1.1).
If I want to convert a String to Locale object, I assume I need to
define some sort of PropertyEditor??
Any help is appreciated.
Thanks,
Mujahid

Yep thats what I ended up doing. The code
(Locale)ExpressionEvaluatorManager.evaluate("locale", expr,Locale.class, this, pageContext)
was working against standard.jar (1.0).So just not sure why this is breaking all of a sudden.
Thanks,

I'm not sure about the convertor, but could you instead just do:
String localCode = (String)ExpressionEvaluatorManager.evaluate("locale",
expr, String.class, this, pageContext);
Locale locale = new Locale(localCode);
At least that way your only asking the ExpressionEvaluatorManager to deal
with a basic type that by default it knows how to handle. I know, it's
not one concise line then :)
