Hi,
I get the same problem.
I’am evaluating the jqxKanban to use it in my project.
For test purpose i resolved this issue edditing the jqxkanban.js file on my node_modules folder.
node_modules/jqwidgets-scripts/jqwidgets/jqxkanban.js
replacing the line bellow in the method addItem:
l.data("kanban-item-id", e);
to
l.data("kanban-item-id", b);
This works fine only with your own id.
They have some issue in the other part of code that set the “new id”:
var e = (n._source != null) ? n._source.length : 0;
You can’t get just the lenght of the array for a new id.
You will get a classic problem when add and remove itens…
I’m waiting the fix to, maybe, use it in my project…
Thx.
