I have read the other post about this at T4MVC OptionalParameter values implied from current context and I am using the latest T4MVC (2.11.1) which is suppose to have the fix in. I even checked checked to make sure that it's there -- and it is.

I am still getting the optional parameters filled in based on the current context.

For example: Let's say I have a list that is by default ordered by a person's last name. I have the option to order by first name instead with the URL

http://localhost/list/stuff?orderby=firstname

When I am in that page, I want to go back to order by first name with the code:

@Html.ActionLink("order by last name", MVC.List.Stuff(null))

the link I wanted was simply

http://localhost/list/stuff

without any parameters to keep the URL simple and short - invoking default behaviors within the action. But instead the orderby is kept and the url is still

http://localhost/list/stuff?orderby=firstname

Any help would be great. I know that in the most general cases, this does remove the query parameter - maybe I do have a specific case where it was not removed. I find that it only happens when I have the URL inside a page that I included with RenderPartial.

My actual code is

<li>@Html.ActionLink("Recently Updated",  MVC.Network.Ticket.List(Model.UI.AccountId, "LastModifiedDate", null, null, null, null, null))</li>
<li>@Html.ActionLink("Recently Created",  MVC.Network.Ticket.List(Model.UI.AccountId, "CreatedDate", null, null, null, null, null))</li>
<li>@Html.ActionLink("Most Severe",       MVC.Network.Ticket.List(Model.UI.AccountId, "MostSevere", null, null, null, null, null))</li>
<li>@Html.ActionLink("Previously Closed", MVC.Network.Ticket.List(Model.UI.AccountId, "LastModifiedDate", null, "Closed", null, null, null))</li>

the problem happens when someone clicks Previously Closed and and go to ?status=closed. When they click Recently Updated, which I want to the ?status so that it shows the active ones, the ?status=closed stays.

Any insight would be greatly appreciated.
