Access to public properties inside a custom plugin

[De Pauw Jimmy]

Hello all,

This is probably more like a GLib issue but i have a problem with using 
gchar public properties inside the code of my own plugin.
I have installed many properties following what i could find in the code 
of other plugins.

My problem occurs when i want to retrieve the value of a property inside 
one of the transformation function (transform_ip) or change_state.
Whatever i want to retrieve is not initialized even though the 
set_property is properly called with the good value.

Am i supposed to call gst_my_plugin_get_property by myself or is there 
another function i need to call?
