I've been experimenting further with this issue using IE and Firefox. The
only conclusion I can draw is that it is completely unreliable. Sometimes
it will work fine for a few clicks (adding filters) but, no matter what, I
will ultimately receive the "Communication error with server" message.
This error is shown in the script below and is called when an ajax error
occurs.
This performance is the same with the ontology I sent earlier as well as my
internal ontology.
My current thinking is that something is timing out but I do not have the
skills to pinpoint what the problem is. I have Firebug but do not know
what to look for. The TBC error log does not show anything.
Any additional thoughts on this issue? I will check the TBL implementation
once I have time to upgrade the server to 3.6.0.
Thanks,
Tim
