Howard,
Thanks. Actually, the spot that uses this call isn't a component,
it's a generic implementation of IPropertySelectionModel (which I
inherited from a previous post on the tapestry list). Honestly, I
don't really know what getParsedExpression() does, so it is difficult
for me to tell why I need to get parsed expressions.
This might be a dumb question, but is it possible to inject a service
into a non-component? I'm not clear on how I would do that.
Thanks,
Eric
public String getLabel(int index) {
Object obj = getOption(index);
if (obj == null) {
return noSelectionLabel;
}
String realValue = null;
Object parsedExpr = OgnlUtils.getParsedExpression(property);
if (ExpressionEvaluatorImpl.)
try {
realValue = (String)Ognl.getValue(parsedExpr, obj);
} catch (OgnlException ex) {
throw new RuntimeException(
"ListPropertySelectionModel: Couldn't read " +
property, ex);
}
return realValue;
}

Yes, you'll need to inject the tapestry.ognl.ExpressionCache service.
However, given that expression caching is built into the
tapestry.ognl.ExpressionEvaluator, service don't see why you would
need to get parsed expressions.

Hi,
In a 3.0 application I made use of some OgnlUtils API. The class
appears to be gone in 4.0.
Is there a suggested 4.0 replacement for the following:
OgnlUtils.getParsedExpression(property);
Thanks!
Eric
