SPA - BreezeJS - Entity Framework - Error with predicate

Apologies if this has been already been answered, I am brand new to SPA applications with Durandal, Knockout and BreezeJS - Entity Framework and brand new to Stackoverflow. The code below is what is giving the error. The p2 is the new line of code I added. If that predicate is removed, the query works fine. But, I need this query to also filter on the expanded table ideaComments.

    var p1 = breeze.Predicate.create('ideaId', 'eq', ideaId);
    var p2 = breeze.Predicate.create('ideaComments.isAdminComment', '==', false);
    var predicate = breeze.Predicate.and([p1, p2]);

    var query = EntityQuery.from('Ideas')
        .expand(['ideaComments', 'ideaStatus'])
        .where(predicate);

The error that is being given is as follows:

Error retreiving data. The parent value for a property access of a property 'IsAdminComment' is not a single value. Property access can only be applied to a single value.

Thank you in advance for any help. :-)

assuming an idea has 0..N idea-comments, you'll need to use the any/all filter operator like this:

var p2 = breeze.Predicate.create('ideaComments', 'any', 'isAdminComment', '==', false);

or this:

var p2 = breeze.Predicate.create('ideaComments', 'all', 'isAdminComment', '==', false);
