RE: [flexcoders] Passing Models into MXML components...

[Matt Chotin]

What’s the error?  Are you working with strongly typed objects?  If so, does the object have the properties you’re trying to access declared?   The key to binding is to use strong types (as Tracy pointed out).  There are other binding debugging tips listed on my blog and in the docs (which for 1.5 is actually an updated version of my old blog post).   Matt   From: Scott Barnes [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 22, 2005 8:53 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Passing Models into MXML components...   oops thought I had that heh. I did however find another stumbling block and that is if have a nested child within that object... employeeProfile.TRAVEL.PASSPORT.fName = "Scott" that will throw the error again (as the compiler seems to throw a darky if the object doesn't physically exist when it goes to compile or something along those lines) On Tue, 22 Mar 2005 23:50:39 -0500, Tracy Spratt <[EMAIL PROTECTED]> wrote: > > Also you should explicitly type the declaration. > public var employeeModel:Object = new Object(); > > This helps avoid binding issues. > > Tracy > > > -----Original Message----- > From: Scott Barnes [mailto:[EMAIL PROTECTED] > Sent: Tuesday, March 22, 2005 6:57 PM > To: flexcoders@yahoogroups.com > Subject: Re: [flexcoders] Passing Models into MXML components... > > heh it helps if you initialize the variable inside yoru MXML Component.. > > public var employeeModel; > > should be > > public var employeeModel = new Object(); > > that seemed to have done the trick..... > > eg: > --index.mxml--- > > <mx:Model id="testModel"> > <firstName>Scott</firstName> > </mx:Model> > > <inco:dspTravelProfile employeeModel="{this.testModel}" /> > > -- dspTravelProfile.mxml-- > <mx:Script> > <![CDATA] > public var employeeModel = new Object(); > ]]> > </mx:Script> > > <mx:FormItem label="First Name:"> > <mx:Label text="{employeeModel.firstName}"/> > </mx:FormItem> > > On Tue, 22 Mar 2005 11:00:19 -0800, Blake Kadatz <[EMAIL PROTECTED]> > wrote: > > > > I ran into this as well.  The ugly way around it is to move the code > > from the externally referenced file into the main file.  So in your > > case, that would be put the dspTravelProfile.mxml code into > index.mxml. > > However, for anything more than a small app, that's clearly > > unacceptable.  However, given that it's not able to find certain > > properties, perhaps it's possible to give Flex some hints on where > > employeeModel is being defined so that it's able to resolve references > > across different files? > > > > Blake > > > > > > -----Original Message----- > > From: Scott Barnes [mailto:[EMAIL PROTECTED] > > Sent: Monday, March 21, 2005 9:56 PM > > To: flexcoders@yahoogroups.com > > Subject: [flexcoders] Passing Models into MXML components... > > > > I have a really weird situation here, basically i have: > > > > --index.mxml--- > > > > <mx:Model id="testModel"> > > <firstName>Scott</firstName> > > </mx:Model> > > > > <inco:dspTravelProfile employeeModel="{this.testModel}" /> > > > > -- dspTravelProfile.mxml-- > > <mx:Script> > > <![CDATA] > > public var employeeModel; > > ]]> > > </mx:Script> > > > > <mx:FormItem label="First Name:"> > > <mx:Label text="{employeeModel.firstName}"/> > > </mx:FormItem> > > > > When I first save/change the physical mxml and then run, i get this > > message in the compiler: > > > > "Changes to unknown property, firstName will not be detected." > > > > -THEN- > > > > I hit refresh again, and it goes away?
