[flexcoders] databinding question
Quick question...why are these different:
Versus:
mainContent.createChild(ReportingDatesPanel, "", {width:
"100%", height: "100%", portfolio: selectedPortfolio});
When the selectedPortfolio object changes in the main app with the MXML
in first example above, the custom component recognizes the change in the
selectedPortfolio object and performs the correct action.
If I have the main application dynamically create the custom component
with the code in the 2nd example above, if the selectedPortfolio
object changes, the dynamically created custom component does not see that
change and none of the actions that I want to take place, actually take
place. I’m guessing this is a databinding issue…am I supposed
to set the portfolio attribute differently to catch changes in this object when
dynamically creating the custom component?
Any help is greatly appreciated.
Thanks,
Rob

RE: [flexcoders] databinding question
Nevermind, I just found a past post from
Matt saying databinding can only be done from MXML right now and not
programmatically. Sorry for the post!

RE: [flexcoders] databinding question
It’s probably because of the way
they are instantiated. dispatchEvent() is a mix-in from UIEventDispatcher.
You might try adding ChangeEvent to the
component once it is created. Just a thought.

Re: [flexcoders] databinding question
Hi,
Databinding is a special beast in flex, and is set up in mxml->as compiling
The compiler needs the metadata to figure out what events it has to
listen to for each property (or perhaps just use getters setters). It
then sets up a complex mechanism of watchers and stuff to make binding
happen.
This is the reason why it is only supported in mxml for now.
If you want the same functionality on runtime you have some choices:
- use the old flash binding api ( not possible I assume )
- create your own
- wait for as2lib's future release. I'll be donating a quite powerful
databinding framework soon (well, not that soon if work keeps me this
busy )
it is flex compatible, supports chains and different types of watchers.
Best,
Aldo
PD: Sorry for the delay Simon, I've been busy as hell at work.
