hY,

I have just tried to do what u wrote.

The problem is the following:

losTitulos = ” ['ID', 'Ficha']“;

lasColumnas = “[ {name:'ID', width:50, hidden:true},”;

lasColumnas += “{name:'Ficha', align:'center'}]“;

grid:

colNames: losTitulos,

colModel: lasColumnas,

now … after using firebug the script looked like this:

colnames: ” ['ID', 'Ficha'] “,

but we need:

colnames: ['ID', 'Ficha'], // without ” “

and the same for colModel.
