error in chartfx javascript webresource.axd after callback to resize image chart

[tymeware]

we are long term users of chartfx and have gone through many versions

we followed the sample code used to resize image charts via some onload/onresize javascript that does a callback

after the callback code, the chartfx javascript blows up on this line

// Upate viewstate

var viewStateObj = MM_findObj('__' + context + '_VIEWSTATE');

viewStateObj.value = viewState;

error :

Microsoft JScript runtime error: Unable to set value of the property 'value': object is null or undefined

latest version of chartfx7 webforms

anyone? Francis?

To clarify, this only happens when doing a callback for an image.

The callback on a .net chart is fine.

I would be surprised if this did not happen to anyone else or that support at softwarefx is unaware of the issue.
