Version: 1.1.1 (using KDE KDE 3.1.1a) Installed from: Mandrake RPMs For PHP development, "array" and "mixed" types would be helpful as both method parameters and function returns. Umbrello currently doesn't support either of these.
These can be datatypes.
In KDE 4.11.5 (umbrello version 2.11.5) array is restricted word and umbrello doesn't allow to add this kind of type.
