I was able to reproduce the issue, please refer below:-
Just want to confirm, you have "D_ConsolidateWorkList" reference available under "Pages and Classes" tab?
Also, please make sure you have your property, <Account> is in the same context or in the parent class.
I too faced the same issue, as suggested my colleague Ujjawal. You shouldn't have the parameter name in the data page reference, rather you can directly pass property name with "." operator. I ain't sure but one strange thing I noticed, try to have the same parameter name as in data page.
