+	  Issue264 & Issue268 (Removed bugs in the caching mechanism)
+
+	* src/main/java/de/intevation/gnv/state/DefaultInputData.java: Implemented
+	  hashCode() and equals(.) method. The hashCode() method is used while
+	  creating hashes for caching elements (see StateBase).
+
+	* src/main/java/de/intevation/gnv/state/StateBase.java: Improved hash
+	  creation. The hashes are used as keys for the caching mechanism. The key
+	  contains the uuid of the current artifact, the state id and a hash code
+	  created by InputData elements. User input is stored in a TreeMap instead
+	  of a HashMap, because the elements in a TreeMap are sorted. This is very
+	  import for us, because we need a defined order to create equal hashes if
+	  the input data elements, uuid and state id are equal.
+
+	* src/main/java/de/intevation/gnv/state/MeasurementState.java: Replaced the
+	  HashMap to store user input with a TreeMap which elements are sorted.
+
+	* src/main/java/de/intevation/gnv/state/profile/horizontalcrosssection/HorizontalCrossSectionMeshOutputState.java,
+	  src/main/java/de/intevation/gnv/state/profile/verticalcrosssection/VerticalCrossSectionOutputState.java:
+	  Added some more debug output that shows the usage of the cache.
+
+	* src/main/java/de/intevation/gnv/state/profile/horizontal/HorizontalProfileMeshCrossOutputState.java:
+	  Removed a critical bug that avoided using this product type if no cache
+	  have been initialized.
+
+	* src/main/java/de/intevation/gnv/state/OutputStateBase.java: Adjusted
+	  getHash(.) method call.
