About GUI juju control panel

[Sameer Zeidat]

Anant,

Juju by design does not enforce parameter changes. It's basically up to the charm writer to apply the change or silently ignore it. Juju, and hence the GUI, will accept the change and store it regardless.

Since juju has no notion of "read-only" parameters, it's the charm writer's job to document which of his parameters are only used during installation, and which are available to change afterwards. Many times you'll end up learnig how a parameter change is handled by trial, or by looking inside the charm hook script.

That's my understanding.

You got me right John, I am saying the same. It allows me to set 
password "" , but that doesn't actually unset the password in the 
application.
