if you create a testcase and attach it as a pull request i can take a look. or a quickstart attached elsewhere would also work. -igor On Thu, Nov 17, 2011 at 4:35 PM, Jablow, Eric R wrote: > No, we are using only the stock models, I think.

No, we are using only the stock models, I think. In any case, the particular test class uses CompoundPropertyModel.

Re: Debugging a NPE from a ModelPropertyResolver
it seems like there is a buggy implementation of IPropertyReflectionAwareModel somewhere. did you implement your own model that implements that interface? seems like there is a model somewhere that is a IPropertyReflectionAwareModel but it returns null for all getSetter/Getter/Field() methods... i will add an exception so it will be easier to flag where this is happenning, maybe you can try with a snapshot -igor On Thu, Nov 17, 2011 at 2:17 PM, Jablow, Eric R wrote: > I am trying to use Igor's wicket-validation-bean project, and I've managed to > make a mistake where I'm getting a NullPointerException from when > ValidationForm attempts to add property validators.
