Strings in PropertyEditorSupport [message #144341]

I have a simple String property named x.
I call xPropertyDescriptor.setPropertyEditorClass(XEditor.class);

XEditor is:

public class XEditor extends PropertyEditorSupport {
private static final String[] CHOICES = {"a", "b", "c"};

public String[] getTags() {
return CHOICES;
}
public String getJavaInitializationString() {
return (String)getValue();
}
}

The combo opens fine. But when I choose a,
VE generates
o.setX(a);
instead of
o.setX("a");
This doesn't compile particularly well.

How do I make it return a String?

Also, what is getJavaInitializationString?
The JavaDocs aren't helpful.
Is there more thorough documentation anywhere?

Thanks,
Eli

The javainitializationString has to be the exact syntax of java that you
want to be in the set property statement. So if you return just "a" then
it means the variable a. If you wanted the string "a" then you need to
return "\"a\"".

Being the exact java syntax means you can do expressions and not just a
string, e.g. "\"A\"+Integer.MIN_VALUE" would be turned into

setX("A"+Integer.MIN_VALUE)
