Re: [flexcoders] Re: How to properly subclass a component using mxml

You're missing the namespace to map mx: xmlns:mx="http://www.adobe.com/2006/mxml"   Put that in your root tag.   ----- Original Message ----- From: hank williams To: flexcoders@yahoogroups.com Sent: Thursday, July 06, 2006 12:51 PM Subject: [flexcoders] Re: How to properly subclass a component using mxml One guess I have is that there are issues regarding using mxml to populate an *inherited* field. In this case "columns" is not a component, but a field which contains an Array of of DataGridColumn objects. But the error that flex gives indicates that it thinks "columns" is supposed to be a compoent because the error message is "could not resolve <mx:columns> to a component implementation." Is it just the fact that columns doesnt have a capital letter that should tell the compiler that this is a field and not a component? Should it just be looking first for fields first and then components? This seems like a relatively basic issue. Someone out there must know!?

The problem is that if I try to use the new component as if it was a dataGrid, certain things dont work. For example: <myComp:BetterDataGrid>      <mx:columns>             <mx:DataGridColumn headerText="Song Name" dataField="label"/>             <mx:DataGridColumn headerText="Artist" dataField="label"/>     </mx:columns> </myComp:BetterDataGrid> in the above example, it doesnt like me using the columns construct to define the columns. In order to define columns in this way I need to put then in the actual BetterDataGrid component as opposed to in this instance. This makes it doggone hard to use BetterDataGrid as a generic "better dataGrid" since I cannot define its behavior on an instance by instance basis. I am sure what I am doing wrong here is simple, but I dont know what. Any insight appreciated.
