--------------------------------------
Summary: An angular error occurs when reading a stored date object
Key: ZEPPELIN-2832
URL: https://issues.apache.org/jira/browse/ZEPPELIN-2832
Project: Zeppelin
Issue Type: Bug
Components: front-end
Affects Versions: 0.7.2
Reporter: Andreas Koch
The following is my interpretation of what is going on, but please note that I
am not very familiar with angular, so I may very well be wrong.
If an input form with a field of type "date" is bound to an angular variable an
error occurs when the stored variable is later read from the note.json file. I
think, this is because the variable is stored as a string and that string and
angular does not convert the string back to a date.
The error can be reproduced by creating a paragraph like this:
{code:javascript}
%angular
Test date: <input type='date' ng-model='dateObject'></input>
<button
ng-click="z.angularBind('dateObject',dateObject,'20170804-135511_834695103');">Bind</button>
{code}
The variable is then stored in note.json as:
{code:javascript}
{
"name": "dateObject",
"object": "2017-08-01T22:00:00.000Z",
"noteId": "2CQ2X4TT7",
"paragraphId": "20170804-135619_1160533068"
}
{code}
But when the variable is reloaded from the note.json file an error occurs:
Error: [ngModel:datefmt] Expected `2017-07-03T22:00:00.000Z` to be a date
