Sorry Antoine but I have completely lost the thread. Please give us an
example of what (still) does not work for you.
Ah, sorry for the noise.
I don't know why your syntax was not working, but it clearly was not
working.
I saw a bunch of java related issues on command line so I restarted
scilab and boom, both syntax where working perfectly.
I have no idea what happened and how to reproduce it.
See below the example GUI I built using the new get/set syntax.
I think an example showing the full power of tagPath to distinguish two
uicontrols with same tag but different parents (with different tags)
could be useful too.

get() and set() can now use a tagsPath, that might be less ambiguate
than using findobj(), that returns the first component with a matching
tag (unless only unique tags are defined). The documentation of
set() is
being overhauled
<https://antispam.utc.fr/proxy/1/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/bugzilla.scilab.org/show_bug.cgi?id=15414>.
You
may have a look to it there
<https://antispam.utc.fr/proxy/1/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/bugzilla.scilab.org/attachment.cgi?id=4997>.
The same work on
the get()'s page is pending
<https://antispam.utc.fr/proxy/1/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/bugzilla.scilab.org/show_bug.cgi?id=15226>.
I tried to use your syntax in a callback and it does not work.
The values returned are not the same than when using findobj and the
old syntax (I always get the initial value for the uicontrol, not the
updated ones).
I'll try to get a minimal working example...
