1.4.5 Messager causes error 'Cannot read property options of undefined'

[phunksta]

I have upgraded easyui to 1.4.5 for my application, now during initialisation I encounter an error

Code:

_240 jquery.easyuui.1.4.5.js:3762

TypeError:Cannot read property 'options' of undefined'.

When debugging, I can see the line

Code:

var _243 = $.data(_241, "panel");

_243 is undefined following execution of this.
_241 is a div.messager-body.panel-body-panel-body-noborder.window-body
_242 is undefined

the call stack is

Code:

_240
fn.panel.methods.destroy
fn.window.methods.destroy
fn.dialog.methods.destroy

_2b2() against div class="messager-progress>
