Re: [flexcoders] Re: cellRenderer not recognizing click events for Custom Mxml Cell Renderer

[Anatole Tartakovsky]

Simplest way to pinpoint the problem is to keep generated files and review generated code. You can change the code in click="" to click="mx.utils.Delegate.create(this, click)" if you think that it fails context recognition. In most cases we would just delegate processing to container with click="listOwner.dispatchEvent({type:'arrowClicked',...})     I will try to publish dynamic datagrid demo on one of our external servers this week.

I have traces in both my 'setValue() and 'arrowClick' methods. I see the trace statements for both the setValue(...) and arrowClick(event) methods when the com.StatusPicker cellRenderer is applied to the mx:Datagrid mxml tag. However, for the dynamic datagrid, I only see the trace statements for the setValue() method and no traces occur when I click the arrow. arrgh. so frustrating. The fact that it renders it correctly is the most frustrating part...why the click event that is dispatched doesn't get picked up makes me curious to know what Macromedia's code does when applying a cellRenderer b/c obviously I'm missing that in my mxml file. Is there an example mxml file that does work with dynamic datagrids I can try to plugin? I guess a last resort option is to write the entire cell renderer in an Actionscript class but that I fear woul dlead to more problems (and Actionscript forums) for me!  Cheers. --- In flexcoders@yahoogroups.com, "Anatole Tartakovsky" <[EMAIL PROTECTED]> wrote: > > I am using both mxml and AS - works in both. Try to use trace in setValue to verify if the trace output is sent. Also, I am not sure what you mean by saying that you add mxml dynamically - it is either referenced in the code statically with var _fake:com.StatusPicker=null; or has to be in RSL preloaded into the application. > HTH, > Anatole > > > ----- Original Message ----- >   From: Kevin Ewok >   To: flexcoders@yahoogroups.com >   Sent: Tuesday, February 07, 2006 1:17 PM >   Subject: [flexcoders] Re: cellRenderer not recognizing click events for Custom Mxml Cell Renderer > > >   I have traces at the beginning of my 'arrowClick' method which is >   linked to the click event of the button.
