+++ Compression Bug in F2.js download

[timburcham]

Inside the F2.js default download, EasyXDM is included. Inside the EasyXDM line (line 60), 2 references of '+ ++' are included. When run through some compression engines, this is compressed to '+++', which breaks some browsers like Firefox.

The fix is to convert the line just slightly to protect the second and third plus:

• ++i

to

• (++i)

Offending line in EasyXDM is line 2402: _callbacks["" + (++_callbackCounter)] = callback;
