[FIX] web: consider correct viewtype when loading data

Before this commit, when loading the data and calling the prostprocess,
the viewType was not correctly passed which could lead to broken
behaviour. For example, if one was to load a record from a list view
embedded in a form view, the viewtype passed was the list which
prevented to load the data from the form view.
