Install menu set when...

In my solution I am applying custom menus based on a calculation, using the 'specify' option for 'Install menu when'

 

The basis of the calc is

 

Install menu set when [isEmpty (GlobalField)]

 

My GlobalField is definitely a global FIELD (not $$var) and I use this to track whether a script is running or not. If a script is running then I want the custom menu to be removed, so I set the GlobalField during the script execution. Unfortunately the menu does not disappear as intended, however the calculation is correct.

 

I tried manually entering data into GlobalField and still the menu does not remove.

 

If I change window mode then the menu responds and is removed.

 

Whilst I also know I can use the script step 'Install menu set' this is not desirable as I have hundreds of scripts using the same technique.

 

Any one know why the 'Install menu set when' feature does not respond in a dynamic way - I didn't see any limitation in the FM docs.

 

Many thanks

Instead of setting a global during script execution you could use the script step Install Menu Set [standard FileMaker Menus]. You'd have to change this in hundred of scripts. Why did you create a hundred scripts with a function that's not working yet?

 

I'm not aware of a calculation function "Install Menu Set when ... ". Please elaborate.

 

I'm also curious why you would get rid of a menu set during script execution. And what happens after the script has finished execution?

There is no "Install Menu Set when" calculation.

 

But there is an "Install Menu when" calc that is part of the definition of a custom menu.

BruceR: Thanks for the correction, this is the option I am discussing

 

hbrendel: I didn't create hundreds of scripts with a function that doesn't work (yet) as my original system design pre-dates Custom Menus - in fact my method of script arbitration has been running for 15 years!

 

The menu I want to install/remove provides direct access to some 15+ other files that comprise the solution and it's necessary NOT to be able to use some menus whilst a script is running in the current file.

 

I understand what my options are in terms of modifying the scripts, however, my question is:

 

Any one know why the 'Install menu when' feature does not respond in a dynamic way?

 

Thanks

'Install menu when' operates - as it says - the moment a menu is installed. So it does not when some data (field / variable) changes.


Most of the times menu options are not available during script execution. Are they in your case? Did you test this? Could you describe it?

But did you add a script step 'Set Variable [$$xxxxx]' to each script? You could as well have taken 'Install Menu Set' in place.

HBrendel: have you even tried that? Have you looked at the documentation? That's a circular; and incorrect; statement.

I think you're looking in the wrong place. How does FileMaker know when a field value has changed?

I suspect you will have to do something that refreshes the window, either a direct refresh, change of record, etc.

Agreed.  The menus live at the file/application level, not at the data level so I would not assume that there is any data notification going on.
