This bug has been around for quite sometime but we’ve only just found steps to reproduce it.
Unable to drag tasks on work board to empty columns.
Uncaught TypeError: Cannot read property 'getAttribute' of null at Function.getData (core.pkg.js:166) at result._onmovecard (WorkboardBoard.js:36) at result.<anonymous> (core.pkg.js:69) at Function.pass (core.pkg.js:153) at Function._dispatchProxy (core.pkg.js:148) at Function.invoke (core.pkg.js:91) at result.proto.invoke (core.pkg.js:67) at result._drop (core.pkg.js:1347) at result._ondrop (core.pkg.js:1343) at Function.pass (core.pkg.js:153)
The task remains dim and cannot be moved. Other tasks cannot be moved until the page is refreshed.
We can work around the problem by moving a task into a column via the task page so at least one task is in the column.
This occurs on project workboards and sub project workboards.
The task should successfully move to the new column and the interface should become available to move other tasks.
