I really don't understand. Are you saying that I should write a
function to do the comparison? Nothing I saw in the JavaDoc explains
why I can't search objects on the result of a function although I'm
getting an error that says that the function isn't available. I have
no trouble taking the info I'm searching on and displaying it in the
WOComponent I'm working on.

thanks,
matt

Hi, Matt,

Take a look at the EOQualifier JavaDoc and search for "Using
Selectors in Qualifier Expressions".

I think you'll find your answer there.

Regards,
Jerry
