why is menu title not render properly on FR935?

There's some bug in the FW. So there's a chance the bug is in the code that reads the resource compiled from the xml and there it has something like:

setTitle(language)

instead of:

setTitle(xmlMenu.title)

So your idea of programmatically creating the menu is not bad IMHO

Yeah, that was my initial idea - after thinking about it for 5 minutes, I questioned it.

I questioned to what extent the menu-building code is generated by the resource compiler as opposed to being in the device firmware. Sorry I did not make that abundantly clear.

If all the menu-building code is actually generated by the resource compiler (which seems likely - why would Garmin waste code in the firmware to do something the compiler can do?), then it could also be that it's a bug in the old Menu class (which is used by the <menu> resource tag). And it could be that the reason I didn't see it on FR935 with my apps is because I used the newer Menu2 class.

I tried the Menu SDK sample for fr935, which includes the following menu definition:

<menu id="MainMenu" title="@Strings.MainMenuTitle" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="https://developer.garmin.com/downloads/connect-iq/resources.xsd">
    <menu-item id="Item1" label="@Strings.MenuLabel1"/>
    <menu-item id="Item2" label="@Strings.MenuLabel2"/>
</menu>

Rez.mir (the generated intermediate representation for resources) has a MainMenu class corresponding to the MainMenu resource:

Note how, after creating a new instance of the Menu class, the generated code grabs the title resource and calls setTitle. This mean there should be no difference (as far as the title goes) in creating Menu from a resource vs. creating it from code.

                %tmp.5 = getv ? :Menu;
                symbol [ setTitle %tmp.6 37 21 29 ];
                %tmp.6 = getv function %tmp.5 :setTitle;

                %tmp.8 = getv function %tmp.7 :loadResource;
                symbol [ $ %tmp.9 37 52 53 ];
                %tmp.9 = getm $;
                symbol [ Rez %tmp.10 37 54 57 ];
                %tmp.10 = getv %tmp.9 :Rez;
                symbol [ Strings %tmp.11 37 58 65 ];
                %tmp.11 = getv %tmp.10 :Strings;
                symbol [ MainMenuTitle %tmp.12 37 66 79 ];
                %tmp.12 = getv %tmp.11 :MainMenuTitle;
                %tmp.13 = invoke %tmp.7 %tmp.8(%tmp.12);

Therefore, my conclusion is that it's likely an issue with the very old Menu class, and the workaround is probably to use the newer Menu2 class. Note that Menu2 can also be used from resources (the tag is <menu2>)

Indeed, <menu> isn't barely mentioned in the Resources core topic docs now.

https://developer.garmin.com/connect-iq/core-topics/resources/

(there's still an old example of <menu> but the detailed docs refer to <menu2>)
