Sounds like a good plan. See you manana mi amigo. -----Original Message----- From: "Kevin" <[EMAIL PROTECTED]> To: [email protected] Sent: 3/21/07 2:33 PM Subject: Re: [flexcoders] PopUp Returning NULL
I think I figured it out. Because I am using the Cairngorm Model Locator pattern to control the popup state (thus the ObserveValue class) I need to be very strict about not trying to call popups directly. In this case, when I called the popup via a direct function call, I was not updating the model and thus there was a NULL value on the model that would have otherwise been set. When the popup opened from a direct call, it saw this NULL value and thew an error. My mistake....I need to stick with my pattern for better or for worse It is so tempting to take short cuts though! Thanks for the help though. - kevin On Mar 21, 2007, at 2:14 PM, Kevin wrote: > > I am not using modules and I also tried to comment out the > ObserveValue tag to see that was causing a problem.
