What is your Wicket version? This is from CVS HEAD
* @param modelObject
* The model object, which may or may not implement IModel
and the whole file does not contain the word OGNL. Actually there is
only one file NumericTypes.java which contains the word OGNL. Which
makes sense as we don't use OGNL any more. The performance of OGNL was
quite poor and because usually you'll need only a very limited subset
of OGNL we decided to reimplement this piece of code. If you really
require full OGNL support, you could create your own OgnlPropertyModel
which uses the OGNL jar.
