Textarea event bug in Flash target

[turdparty]

Current Behavior

When you click on the scrollbar-thumb to scroll the text in a textarea the following error occurs for the flash target. (Not an issue for the android target.)

Error #1034: Type Coercion failed: cannot convert haxe.ui.events::FocusEvent@6e608d1 to haxe.ui.events.MouseEvent.

Steps to Reproduce (for bugs)

1. Just take the most basic haxeui example and add a textarea.

<vbox> <label id="label1" text="Simple HaxeUI application" /> <button text="Click me!" onClick=" label1.text='Button clicked!' " /> <textarea text="1\n2\n3\n4\n5\n6\n7\n8\n9\n0\n1\n2\n3\n4\n5\n6\n7\n8\n9\n0\n1\n2\n3\n4\n5\n6\n7\n8\n9\n0\n1\n2\n3\n4\n5\n6\n7\n8\n9\n0\n1\n2\n3\n4\n5\n6\n7\n8\n9\n0\n"/> </vbox>

`import haxe.ui.Toolkit; import haxe.ui.HaxeUIApp; import haxe.ui.core.Screen; import haxe.ui.core.Component; import haxe.ui.macros.ComponentMacros;

class Main { public static function main() { Toolkit.init(); var app = new HaxeUIApp(); app.ready(function() { var main:Component = ComponentMacros.buildComponent("Assets/UI.xml"); app.addComponent(main); app.start(); }); } } `

Same problem on HashLink backend, simple click on textarea leads to crash. Neko/CPP is fine.
