So the problem with the values helper was that it will only take array of objects and i was passing a string…I have corrected the code by passing an array of objects..Below is the corrected code..
body: [
{
type: 'listbox',
name: 'type',
label: 'Panel Type',
value: type,
'values': get_author_list(),
tooltip: 'Select the type of panel you want'
},
]
.....
function get_authors_list() {
var result = [];
var d = {};
d['text'] = 'Default';
d['value'] = 'default';
result.push(d);
return result;
}
