I want to add new fields(columns) to this.  i can do that, but I get crzy JS errors when i do.

----------------

Example:

columns = [ // 'AccountId', 'Name','Sites','StageName','CloseDate', 'Amount', 'Id'
{ name:'Account',sfname:'AccountId', comparator: nameCompare ,
width: 128, readonly:true, formatter: turbo.grid.format.link },
{ name:'Name', comparator: nameCompare ,
width: 188, readonly:true , formatter: turbo.grid.format.link } ,
{ name:'Sites', sfname:'Sites', comparator: nameCompare ,
width: 188, readonly:true , formatter: turbo.grid.format.link } ,

[ turbo.grid.columns.sfenumerated, { name:'Stage', sfname:'stagename', comparator: stageCompare, width: 125,
options: getOptionsArray(bean,'stagename'), values: getOptionsArray(bean,'stagename') } ],

{ name:'Close Date', sfname:'CloseDate', comparator: dateCompare ,
width: 75, align: 'left', formatter: turbo.grid.format.dateonly, editor: turbo.grid.edit.dateonly },
{ name:'Amount', sfname:'Amount' ,
width: 86, align: 'right', digits: 4, formatter: turbo.grid.format.sfmoney, editor: turbo.grid.edit.decimal}
,{ name:'Id', formatter:null }
];

---------------------------

I added the custom field 'Sites' to this.  But i get this error message each time:

"Exception thrown, but not caught"
