Adhoc tracking does not work with custom variable of type 'list'

[rowlando]

The request to omniture doesn't have a value for l1 when an array is specified in the trackAdHoc() call.

analytics.setup({
    site: 'global',
    section: 'skyglobal/analytics/demo',
    account: 'bskybdemodev',
    contentType: 'analytics',
    customVariables: [
        {'listOfValues': { list: 1} }
    ]
});

analytics.trackAdHoc(
    {'listOfValues': ['value1','value2']}
);

It works with a single value:

analytics.trackAdHoc(
    {'listOfValues': 'value1'}
);

In the request made to omniture, the l1 value is 'value1'.

Any suggestions?

I suspect when this was first setup there was no need to have a list of values.

It's a bug 🐞

It works if the list is double wrapped like:

analytics.trackAdHoc(
    { 'listOfValues': { 'listOfValues': ['value1', 'value2'] } }
);

Or as you noticed single, string value may be passed. If array is joined with pipe character it's going to give the same result in terms of l1 value.

analytics.trackAdHoc(
    { 'listOfValues': 'value1|value2' }
);
