* added method ZIRenderService.render(JSONArray)
* added support for context parameter property "ztemplates.devMode" (servletContext.getInitParameter("ztemplates.devMode")) that disables as many caches as possible to support tools like JRebel for no redeploy

You will have to update your existing web-xml... read more

Thanx.

sample: added ztemplates-yui project that shows how to integrate ztemplates and YUI. This is not intended to be reused but as an example on how to do it. If someone is interested he could contribute to ztemplates by expanding this to a reusable library. Contact me at dev //@// gerdziegler //.// de

feature: added @ZScript annotation. Provides support for <script src="" type="text/javascript"> declarations on render-pojos that are collected and aggregated by ztemplates, so you need not worry how to deploy the javascript libs in AJAX applications. Also applies to css.... read more

api: a empty string assigned to a ZProperty will now be considered as null value.... read more

feature: changed ZIServletService.sendRedirect so that it also works with Strings as parameter... read more

api: added support for css fragments. Put css into a file in the same directory as the class annotated with @ZRenderer. ztemplates scans the classpath and aggregates all found css to a css-stylesheet accessible with <LINK rel="stylesheet" href="/your-contextPath/ztemplates.css">

This is a bugfix release
