jquery Dialog Modal + datagrid

[Stan92]

Hi,
I've a page with a datagrid that doesn't use the datagrid plugin (and I don't want it uses it).
From this page, I've a jQuery Dialog Modal where I set another datagrid. This one needs to use the plugin.

Using the basic example, I get an alert popup saying "Cannot get property 'options' on null object error" within this function
function _1f8(_1f9,_1fa){
var opts=$.data(_1f9,"panel").options;
....
}

Is there a way to avoid this error? is it a problem with Jquery Dialog modal?
Sorry for this newbie question
Regards,
