From now the deltashell framework has a new kind of view...the IReusableView.
The purpose of this view is to reduce the number of views of a certain type by reusing the existing view with different data.
For example:
If you have a view open for a boundarycondition and double click on another boundary condition the existing view will change to show the other boundary condition. Therefore you will always have only one boundarycondition view open...
Except....when you 'lock' a reusableview. Then the view is tied to the data it shows and when click on other data the view will not be reused and a new view will be opened (if no other resuableview is open). A lock image will be shown in the tab of the view to show it is locked.
If you want your view to have this behaviour you should use IReusableView.
