In the jsFiddle demo, I changed the initialization to be value="1950-04-06" but it still failed to initialize the control. In any case, I do not pass the value as a string but as a DateTime object and the control generates the date as a string in the value attribute.
I can't change the input element type="date" to type="text" since the element is generated by the Kendo control.
And yes, when Kendo is updated in the project, the css, js and wrapper dll are all updated.
Thanks for looking at this Dimo but I am still looking for a resolution, ideally a fixed Kendo build.
