Aha! Number 2 is what I was hoping to hear. Thanks Colin!

Hi Nathan,
You're right, you can't pass arguments in WOComponent bindings, so
your first approach won't work. For any object that implements
Key-Value Coding, you could simply bind up the key name, such as with
an NSDictionary (eg. myDictionary.keyName). However, Hashtable doesn't
speak KVC, so there are a couple of other options:
1. Write an accessor in your WOComponent for that key of the Hashtable:
public String getValueFromHashtable {
return myHashtable.get("keyName");
}
2. Convert your Hashtable into an NSDictionary. There's a constructor
available for that.
NSDictionary myDictionary = new NSDictionary(myHashtable);
I hope that helps,
Colin

Is there an easy way of getting some text out of a Hashtable and into
a WOString? I thought that I could set the binding in WOBuilder to
aHashtable.get("key"), but that does not work.
If there's no simple way, then I'll just right a method to return the
String value.
Thank you,
Nathan
