I looked at this a little more, I just have one more detail I would like to add:
Firebug is reporting the following error: "document.forms has no properties var a5=document.forms[a0];" It is reporting this error in Common1_2_3.js (line 5180). Perhaps this can provide a clue of what might be wrong. Again I am using Trinidad 1.2.3 deploying on GlassFish 2. Thanks in advance for any help.
