drawImage fails wilth self.drawPane msg

Hello,
1. I am using SmartClient Version: v9.1p_2014-07-20/Pro Deployment (built 2014-07-20)

2. This issue is predominantly seen on FF 31.0. But our QA team is also intermittently seeing it on latest chrome and IE11

3. Following is the full-stack trace -

14:29:20.658:XRP5[E]:WARN:Log:Error: http://<IP-ADDRESS>/thirdparty/smartclient/9.1_20_7/system/modules-debug/ISC_Drawing.js

Value: TypeError: self.drawPane is undefined

14:29:20.692:XRP5[E]:INFO:draws:isc_IButton_0:draw(): drawing IButton with parent: [Toolbar ID:isc_globalWarn_toolbar]

Canvas.draw(showing=>undef, undef, undef)

StatefulCanvas.draw(a=>undef, b=>undef, c=>undef)

Layout.layoutChildren(reason=>undef, deltaX=>undef, deltaY=>undef)

[a]Dialog.showMessage(newMessage=>"Page Error:http://<IP-ADDRESS>/thirdpa..."[137], properties=>Obj{title:Warning})

anonymous(message=>"Page Error:http://138.120.140.41/thirdpa..."[137], messageType=>"warn", callback=>undef, properties=>Obj{title:Warning})

anonymous(message=>"Page Error:http://138.120.140.41/thirdpa..."[137], callback=>undef, properties=>undef)

[c]alu_nms_NMSCommon.notifyUser(aInMessage_s=>"Page Error:http://<IP-ADDRESSS>/thirdpa..."[137])

anonymous(aInValue=>"TypeError: self.drawPane is undefined", aInMessage=>"http://<IP-ADDRESS>/thirdparty/smartcl..."[89], 8824, 20, TypeError: self.drawPane is undefined)

4. Here is the sample code -

isc.DrawImage.create({
src: "[SKINIMG]/nms/web/vision/AllGroups.png",
left: left+ 2,
top: 4,
width: 16,
height: 16,
autoDraw: true,
drawPane: aInDrawPane
});

where aInDrawPane is drawPane (which is not null or undefined).

But in ISC_Drawing.js - initImage(src) - ISC_Drawing.jsTypeError: self.drawPane is undefined


Do you have any thoughts on what we could be doing wrong. Would greatly appreciate any help.

Thanks
