Runtime Error 1007 on a simple ProgressBar in Flex 4

Runtime Error 1007 on a simple ProgressBar in Flex 4

- April 25, 2011

this such simple code compiles correctly, i'm getting error below when running

typeerror: error #1007: instantiation attempted on non-constructor.

@ mx.controls::progressbar/createchildren()[e:\dev\4.0.0\frameworks\projects\framework\src\ mx\controls\progressbar.as:1110]

@ mx.core::uicomponent/initialize()[e:\dev\4.0.0\frameworks\projects\framework\src\mx\core\ uicomponent.as:7250]

......

here's code gives error:

<s:titlewindow xmlns:fx="http://ns.adobe.com/mxml/2009"

xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:mx="library://ns.adobe.com/flex/mx"

xmlns:com="com.*" xmlns:folders="services.folders.*"

height.mini="80" height.full="400"

minheight.full="200" minheight.mini="70"

title="upload photos" creationcomplete="initcom()"

currentstate="full" controlbarvisible="true"

width="418" minwidth="400">

.....

.....

<s:controlbarcontent>

<com:iconbutton id="btnadd" tooltip="add file(s)" click="addfiles()" icon="{addicon}"

skinclass="com.skins.iconbuttonskin" width="20"/>

<com:iconbutton id="btnremove" tooltip="remove file(s)" click="removefiles()" icon="{removeicon}"

skinclass="com.skins.iconbuttonskin" width="20"/>

<mx:progressbar id="uploadprog" labelplacement="center" width="100%"/>

<com:iconbutton id="btncancel" tooltip="cancel upload" icon="{cancelicon}" click="onuploadcanceled()"

skinclass="com.skins.iconbuttonskin" width="20"/>

<com:iconbutton label="upload" tooltip="upload file(s)" id="btnupload" icon="{uploadicon}" click="uploadfiles()"

skinclass="com.skins.iconbuttonskin" width="20"/>

<com:iconbutton id="btnview" tooltip="show/hide file(s)" click="changeview()"

icon.full="{viewiconfull}" icon.mini="{viewiconmini}"

skinclass="com.skins.iconbuttonskin" width="20"/>

</s:controlbarcontent>

</s:titlewindow>

if remove progressbar code here, runs fine. 1 line, above error during runtime. line in, design mode doesn't show-up in flash builder 4

any idea issue here?

ps: i've tried normal s:button well, before skinned button component. can't problem.

i'm not able reproduce error following sample:

<?xml version="1.0" encoding="utf-8"?>
<s:application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx">

    <s:titlewindow title="upload photos" width="418" minwidth="400">
        <s:controlbarcontent>
            <s:button id="btnadd" tooltip="add file(s)" width="20"/>
            <s:button id="btnremove" tooltip="remove file(s)" width="20"/>
            <mx:progressbar id="uploadprog" labelplacement="center" width="100%"/>
            <s:button id="btncancel" tooltip="cancel upload" width="20"/>
            <s:button label="upload" tooltip="upload file(s)" id="btnupload" width="20"/>
            <s:button id="btnview" tooltip="show/hide file(s)" width="20"/>
        </s:controlbarcontent>
    </s:titlewindow>

</s:application>
