It appears that the calculation of width of the input tag might be incorrect.
In the debug source for “text” component around Line 6081 contains:
var width = this._settings.inputWidth-this._settings.labelWidth-18;
Most of the time, this._settings.inputWidth is undefined. As a result, the variable width is then given the value: NaN. All calculations and the resulting HTML will contain the width: NaNpx
It currently is not causing any problem since the invalid width attribute is being ignored by the browser.
Thanks,
