[flexcoders] ModelLocator for each modules????
Hi All I'm using Cairngorm in my application, which has different big modules. For example one module may be project management and other contact management. Do I need to make different ModelLocator files for these modules?? Regards Jerry
[flexcoders] ModelLocator - Cairngorm 2
I can't get the reference implementation to compile (pasted below).
Seems to be missing a constructor. How should this be solved keeping
in mind that private constructors aren't supported?
[Bindable]
public class ShopModelLocator implements ModelLocator
{
private static var modelLocator : ShopModelLocator;
public static function getInstance() : ShopModelLocator
{
if ( modelLocator == null )
modelLocator = new ShopModelLocator();
return modelLocator;
}
public var products : ICollectionView;
}

Re: [flexcoders] ModelLocator - Cairngorm 2
What about something like this?
[Bindable]
public class ShopModelLocator implements ModelLocator
{
private static var modelLocator : ShopModelLocator;
public static function getInstance() : ShopModelLocator
{
if ( modelLocator == null )
modelLocator = new ShopModelLocator();
return modelLocator;
}
public function ShopModelLocator()
{
if ( ShopModelLocator.modelLocator != null )
throw new Error( Only one ShopModelLocatorinstance
should be instantiated );
}
public var products : ICollectionView;
}

Re: [flexcoders] modellocator and double bindings
thanks! yes, I am certain.
It seemed to only effect VOs 'owned' by the main VO.
for example, homeAddress is a VO that is a member of myVO.
mymodel.myVO.homeAddress.address1
each VO extended Cairngorm's ValueObject and is tagged Bindable.

Ok, before the big hoorah relase of FB 2 and cairngorm2 I had a app
that has a few forms in it bound to a VO hanging out in the
modellocator. I used double bindings to display and update values in
the VO like this
mx:Binding source={mymodel.myVO.homeAddress.address1}
destination=txtAddress1.text /
mx:Binding source={txtAddress1.text}
destination=mymodel.myVO.homeAddress.address1 /
mx:TextInput width=100% id=txtAddress1 /
things worked swell. Then came the update to Flez 2 and cairngorm and
teh above double binding attack bombs. The txtAddrss1 input box is
diplayed empty and gets updated as empty too. Yuk!
THe approach I have found to work is to use a local var as a pointer
and bind to it. wierd. So this works
[Bindable]
localAddy: Address = mymodel.myVO.homeAddress;
mx:Binding source={localAddy.address1} destination=txtAddress1.text /
mx:Binding source={txtAddress1.text}
destination=localAddy.address1 /
mx:TextInput width=100% id=txtAddress1 /
Any thoughts?

Re: [flexcoders] modellocator and double bindings
holy creations batman! sounds like a good reason. Now, would adding a creationPolicy=all to the root application tag address this maybe?DKOn 7/7/06,

Binding seems to take even if local controls haven't been
created yet. So if you're double-binding is between a null control and an
always-available model locator, the values in the model locator should be
corrupted before the control is created.
On the other hand, if a local variable is used the
double-binding doesn't acually start binding into the model until the local
controls are created.

[flexcoders] ModelLocator
Title: ModelLocator Hi All, How does ModelLocator work? I am looking at the sample store and it makes sense but I am kind of confused. What I have understood so far is that ModelLocator Properties are bound to views and Commands manipulate ModelLocator to update views. Is ModelLocator available to the entire application once it gets initialized on the root level? If it works like that then it means that I'd hardly ever need ViewLocators??? I can create models, initialize them in ModelLocator and use them wherever I want in the app?

RE: [flexcoders] ModelLocator
Title: ModelLocator Great. That sounds exciting and a very good approach. The way Im implementing is that I have a ModelLocator, which has models as properties.

RE: [flexcoders] ModelLocator
Title: ModelLocator
Hi Mehdi
To use ModelLocator and transfer VO is perfectly fine.
Eg. I have a Datagrid dp=ModelLocator.organizations
and when I select in the datagrid I have ModelLocator.organization =
SelectedItem which I send to my J2EE server in your case CF.
import com.VO.*;
class model.ModelLocator implements
org.nevis.cairngorm.model.ModelLocator {
public static function initialise()
: Void {
}
//
public static var
organizations : Array;
public static var
organization : OrganizationalUnitVO;
}
