Limitations of the Umple language or technology should be documented here.

• Umple allows key features of UML to be represented in code, but certainly not all of UML. As time progresses we intend to add more and more UML concepts. Umple is, however, probably the most advanced open-source code generator for Umple, especially with regard to state machines and associations.

• Errors in Java, PhP or other language methods embedded in Umple code are not detected by the Umple compiler unless the compiler is invoked with the -c option (-c - to compile all).
