Re: Component level cache

2016-08-18 Thread Matt Pavlovich 
+1 agreed.  Caching the data (models) coming from data providers and/or 
services is the best approach

Hi,

I am not aware of such component.
Usually the caching is done in the service layer, not in the UI.
But if you prefer to do it with Wicket then do it in a Model that caches
the DB results.

Hi,

I was just wondering if there is some component to instead of let the a
given component to render itself, check if there is a cache and display its
rendered markup, thus avoiding unnecessary rendering, this could be useful
for stateless components that need to display some list of categories from
the database etc.

Something like this:

class Header extends Panel{
 add(new ExpensiveCategoryListView());
}

class Home extends Page{
 add(new CachedComponent("headerContainer", Header.class))
}

The CachedComponent would first check if there is an already rendered
Header instance (could check in an in-memory store like, infinispan or
hezelcast)

What do you guys think?

Without the actual markup there's little we can help you with. What is
the markup that generates these error reports?

wicketstuff-htmlvalidator problem

2016-08-18 Thread Dirk Forchel 
Hi,
we're trying to use the Wicketstuff Html Validator (see
https://github.com/dashorst/wicket-stuff-markup-validator.) with our Wicket7
project. We've built our application with the lates release of Wicket 7
(7.4.0) and with the latest release of wicketstuff-htmlvalidator (1.11).
By the way, our generated Html markup is not valid, but we get all the time
if we're using the validator the following IllegalStateException. Any idea
how to solve the problem?
