javascript erros when dragging to the same element as source #289

Closed GoogleCodeExporter closed 8 years ago

I can actually reproduce it on the flowchart demo 
(http://jsplumb.org/jquery/flowchartConnectorsDemo.html)

Steps:

- Square 4, drag Right Center target endpoint to it source (at Top Middle )

After that, all hell breaks loose: lots of js errors and this node is lost.

cheers,
Pedro

this actually applies to any case where you drag a green endpoint on top of a 
blue one.  the errors reported can vary but all are caused by the same bug.

fixed in 1.4.0 dev.

Hello! I just tested from the master at github and the problem still happens 
with 1.4.0-RC1.

It happens when dragging the connection from its source endpoint to the 
"target" element (that contains the source endpoint)

I tried to intercept on beforeDrop, but not sure how to detect and avoid the 
bug. Any workaround? 

I also noted that some connections are different (maybe not applying css) on 
the version form the master, not sure if you are aware.

cheers.

not sure if it's clear the sequence to reproduce, skipped a attachment in the 
previous comment. Attaching it here.

you'd need to provide jsfiddle with your code in.  on the jsplumb demo in 1.4.0 
it works.
