Need activePage not 0 support for MVVM Intermediate Paging

ZK needs to support the use case of when the activePage does not initialize to 0 when using the paging component with MVVM. This would simply require for setTotalSize() to be called before setActivePage(). setActivePage() gets called first during MVVM and only allows for 0 since totalSize during construction is 1. The direct Java constructor already handles this by calling setTotalSize() first, but via MVVM, it does not. I tried to hack it by creating my own IntermediatePaging class which extends Paging, but the @save direction did not work.

USE CASES

1. User wants to bookmark search results of page >1 or share URL with other person.
2. Our paging of overview items resolve to new page of detailed items where the pageSize=1, but user can easily page from e.g. item 33 to item 34.
3. Show full list of items, but previous page search wants to jump to page 50 to highlight item while showing relative position in paged list.

Simply, this should not throw an exception (assuming we have the data):

<paging pageSize="10" totalSize="100" activePage="33"/>

For my case and VM matching numbers above:

<paging pageSize="@load(searchvm.pageSize)" totalSize="@load(searchvm.totalSize)" activePage="@bind(searchvm.activePage)" onPaging="@command('onPaging')"/>
