+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterMatrix.java:
+	  New class that builds a matrix of checkboxes in the following form:
+
+	           | Column A | Column B | ... | Column N
+	   Value A |    [ ]   |    [ ]   | ... |   [ ]
+	   Value B |    [ ]   |    [ ]   | ... |   [ ]
+	     ...
+	   Value C |    [ ]   |    [ ]   | ... |   [ ]
+
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterMatrixPanel.java: New
+	  UIProvider that uses ParameterMatrix for user input.
+
+	* src/main/java/de/intevation/flys/client/server/ArtifactDescriptionFactory.java:
+	  Create a new IntegerOptionsData instance if uiprovider is
+	  'parameter-matrix' and the input type is 'intoptions'.
+
+	* src/main/java/de/intevation/flys/client/client/ui/UIProviderFactory.java:
+	  Return an instance of ParamterMatrixPanel if the uiprovider 'parameter-
+	  matrix' is required.
