Recently I have moved from 7.10.0 to 7.11.3 and found out that date picker in generated task form is not working in the latest camunda version.
I have tried to search for any additional set up which is now required but couldn’t find anything. If u have found similar problem how did you solve it (embedded forms?)
Did you try to clear the history of the browser?
As I know starting from version 7.11, camunda replaced old angularjs with the newer version 1.7.8 including newer version of angular directives for bootstrap (from version 0.11.2 to 2.5.0)
UPDATE:
If you inspect the html of the datepicker you would notice that datepicker-popup attribute is rendered where uib-datepicker-popup should be rendered instead.
Which means HtmlFormEngine class should be updated.
This line of code protected static final String DATEPICKER_POPUP_ATTRIBUTE = "datepicker-popup";
should be updated as below protected static final String DATEPICKER_POPUP_ATTRIBUTE = "uib-datepicker-popup";
