    Cut/Copy/Paste buttons stop working after fromJSON is called on a kendoSpreadsheet.

    Instead, a JavaScript error occurs: "Error: Unable to get property 'clipboard' of undefined or null reference"

    This is due to spreadsheet._workbook._view being undefined. It appears that this happens when fromJSON is called, as it is defined prior to that call.


    This can be replicated in the example for the fromJSON function. Note that the Cut/Copy/Paste buttons are non-functional:


    Is there a solution to this issue?

    Hi Brett,

    The observed issue in the Spreadsheet widget functionality is a know bug, that has been recently fixed. The next official version of Kendo (R3 2018), which is due in mid September, will include that fix. Therefore, I would recommend you to upgrade the Kendo version in your project as soon as the new version is available.
