Re: [CONF] Apache Wicket > Migration to Wicket 7.0

Re: [CONF] Apache Wicket > Migration to Wicket 7.0
Posted by Martin Grigorov <mg...@apache.org>.
Hi Ernesto,
Thanks for raising this! And for reviewing what we do ! :-)
I think it will be better to update InMethod Grid to the new Tree impl.
I will try to do it at some point. If I don't succeed for some reason I may
copy the old Tree code from Wicket 6.x to InMethod

> >
> > Due to the usage of static method it wasn't possible to extend this

> > The behavior has been reworked a bit to allow this. The new usage is:
> > *MyComponent.java*
> >
> > form.add(new AjaxFormValidatingBehavior("keydown", Duration.ONE_SECOND);
> >
> > or
> > *MyComponent.java*
> >
> > formComponent.add(new AjaxFormValidatingBehavior("keydown",
> Duration.ONE_SECOND);
> >
> > in this case the formComponent's owning Form will be used.

> > RequestUtils#decodeParameters() now strips the "?" from the output value.
