RE: [flexcoders] DataGrid Row Icon

It means your data objects are just plain objects and any changes to
type or name won't be detected.  You can make your object [Bindable] or
better yet, define a custom data class with the appropriate [Bindable()]
events, but I don' think these warning will harm you in this case
although it will slow down the app.

Subject: [flexcoders] DataGrid Row Icon

 

I am having an issue displaying an icon in the first column of a row.
Using the following code I pass two variables to a function the type and
name. The type lets me know if the current row is a Directory or a file,
if its a directory I return the source for the folder image, if its a
file I a parse the filename to get the extension and show that Icon. 

mx:DataGridColumn width=30 sortable=false
mx:itemRenderer
mx:Component
mx:Image
source={outerDocument.setIcon(data.Type,data.Name)} 
verticalAlign=middle
horizontalAlign=center scaleContent=false/
/mx:Component
/mx:itemRenderer
/mx:DataGridColumn


While this is working I keep getting the errors below.. Any help is
appreciated. 

warning: unable to bind to property 'Type' on class 'Object' (class is
not an IEventDispatcher)
warning: unable to bind to property 'Name' on class 'Object' (class is
not an IEventDispatcher)


Thank You

As you said that I started looking at it more and started to write a reply.
The item is declared bindable but when you are in the component it could not
see my variable because it was declared private. i declared the variable and
it works with no warnings now!


mx:DataGridColumn width=30 sortable=false
mx:itemRenderer
mx:Component
mx:Image
source={outerDocument.setIcon(data.Type,data.Name)}
verticalAlign=middle
horizontalAlign=center scaleContent=false/
/mx:Component
/mx:itemRenderer
/mx:DataGridColumn
