Of course, and that's the point I was trying to make ;-)
Please talk me through this:
- so let's say the host UI provides a textbox
- the user types in some characters in that textbox
- how does the host communicate a new parameter value to the plugin, when it
has only the string given by the user?

PS
My thoughts were:
- the host sends the entered value string to the plugin
- the plugin does the necessary conversion from the string to a value
(taking into account the localization settings, maybe using some GMPI
provided set of common functions to help with this?)
- the plugin either accepts the value or refuses it, and lets the host know
