Hi, i just installed the whole Development Suite:
Carbide.C++ (V2.04)
S60 SDK 5 V1
QT for Symbian 4.6

The C++ Development toolchain works fine, so there is no problem. Emulator and Device are working with some Examples and Tutorials for Symbian C++
Now i want to use the QT Framework for development, but the .UI File opening throws a Nullpointer from the qtcppdesigner plugin.
Are there some known issues about the versions?
I read somewhere, that i have to upgrade the Carbide IDE to 2.4 (isnt that what i have?)
or do i have to install another plugin?

here is the whole Stacktrace of the exception:
Code:
java.lang.NullPointerException
