How to Re-load a menu

[Tiki]

Is there a way to re-load a screen in Studio such that it executes the before menu loaded and after menu loaded hooks?

I want to be able to execute a conditional such that when a user makes a particular selection, it sets some variables and then re-enters the screen. I want to do it this way since there is a lot of complex code in the before and after menu loaded hooks that I don't want to duplicate.

A simple refresh() doe not execute these hooks.

I could have the conditional link back to the menu widget (this works - sort of, but it clutters up the history, so if the user then clicks the back button it takes him back to the same screen).

Anything that reloads the menu and activates those hooks will affect the menu history.

But reloading the menu or duplicating the code are not your only choices. Put the common code under a comment that says "Shared code for setting up menu state" or whatever, and then add a secondary reference to it at the point where you need it. (Widget references are covers in Chapter 2 of the Studio manual.)

If you do not want to link back to the menu execute the BeforeMenuLoad and AfterMenuLoad widget chain manually (by reference) and then Refresh().

That is probably what I will have to do. I was hoping there was a more elegant way. Since there are multiple branches under each of the hooks, I will need to make references to each of them (you can't reference directly to the hook widget - instead must reference to each child widget).

I try to make my changes and code references to an existing menu as minimal and non-disruptive to the existing code as possible. This reduces the chance that I will have conflicts with someone else's plugin or that my code will break when Sage updates their STV.

I tend to do what Greg outlined, make a "REM Some descriptive text of what this does" widget the parent of all the widgets that do something related so I can easily reference it in other places of the STV. It's a "poor man's" subroutine, Studio style

if you don't mind mucking with back history like greg pointed out you can reference the menu itself. This will reload the menu and evaluate the attributes, and beforemenuload, etc hooks.

You can also do a "back" command and get it removed from history down it before but don't remember how at the moment.
