Invalid property name?

[Karl Beowulph]

Can someone explain the error Invalid property name to me? I can't seem to find much description as to exactly what triggers it on the web and it's paralyzing a program I'm doing right now.

[Marc Peabody]

From DynaActionForm:
/**
* Return the property descriptor for the specified property name.
*
* @param name Name of the property for which to retrieve the descriptor
*
* @exception IllegalArgumentException if this is not a valid property
* name for our DynaClass
*/
protected DynaProperty getDynaProperty(String name) {

DynaProperty descriptor = getDynaClass().getDynaProperty(name);
if (descriptor == null) {
throw new IllegalArgumentException
("Invalid property name '" + name + "'");
}
return (descriptor);

}

I should clarify.

I've seen the actual coding of the error, but it still makes little sense to me.

What determines if the name is acceptabla or not?

On my current project, it will take one name, and reject others (they are not key words).

[Marc Peabody]

It's acceptable for use only if you've declared it.

Maybe there's a property that is being referring to (perhaps in reset()) that isn't a part of the declared form.

This was a DynaBean though, no reset method I'm aware of.

I would get that error with one name, and then, after changing the variable name in the .JSP and config.XML files, it would work.

Is there something I'm overlooking
