to make an ajax call to store some data after drag & drop operation.
When the ajax call returns an error (application logic error or net problem) I want to move the dragged element to its original/start position, how can I achieve it?
The scenario should be
- user drags A to B
event is called, it triggers an ajax call
- the ajax call returns an error
- inside the
event we get the ajax error
- move A to its original position
- user again move A to B
- everything is ok
- A remains in its new position in B
Steps 6-8 are shown to clarify a successive drag can be done and previous error must be forgotten.
