TableTools.js text export button problem

vasketo

This is the code:

[code]
"oTableTools": {
"sSwfPath": "media/swf/copy_cvs_xls_pdf.swf",
"aButtons": [
{
"sExtends": "copy",
"sButtonText": "Copiar"
},
{
"sExtends": "print",
"sButtonText": "Imprimir"
},
"xls", "pdf", "text"
]
}
[/code]

My problem is that all the options work correctly except the text export option. Nothing happens when i push the button.

Any idea?
