A reminder that Royale emphasizes PAYG and has to live with DAYG (do as you go). For PAYG reasons, the simplest ComboBox probably shouldn't have to support custom itemRenderers. Some subclass is more than welcome to. And I don't think anyone has done it yet so volunteers are welcome.

It might be that we can set the itemRenderer property of the list object as it's created by the combo box's view object, but this feels a little hacky and it would be nicer if we could accomplish this just via MXML or CSS.. cheers -----Original Message----- From: Yishay Weiss <[email protected]> Sent: 22 July 2019 17:43 To: [email protected] Subject: [EXTERNAL] RE: ComboBox list-item renderer Another option is to specify the renderer class as an mxml att [1]. ItemRenderers are not beads, so adding them to the beads list has no effect (it should actually cause an RTE).
