Multiple Paramters for filtering in Dynamic Menu

Content

I want to use multiple parameters in Dynamic Menu for filtering. According to MongoDB docs, this one is valid:

{DistributorId:"|_customer_id|",Username:"|userName_t|"}

But it gives ConcurrentModificationException.

 

I tried following also:

{DistributorId:"|_customer_id|" AND Username:"|userName_t|"}

{DistributorId:"|_customer_id|" & Username:"|userName_t|"}

These two give invalid query error (as expected).
