HINT: before reading any further have a look at http://showcase.omnifaces.org/cdi/Param. Do it yourself is probably obsolete seeing how omnifaces is a de facto standard today. I would probably not have written this if omnifaces had this at the time CDI does not solve specialized problems like injecting a request parameter. That’s supposed to be solved … Read more
To start, the view scope is bound to a particular page/view. Multiple views won’t share the same view scoped bean. The view scope starts with an initial GET request and stops when a POST action navigates with a non-null return value. There are in general the following scenarios, depending on whether the browser is instructed … Read more
This is not Mojarra specific. This is Tomcat specific (JBoss uses Tomcat as servletcontainer). Add the following VM argument to startup options. -Dorg.apache.el.parser.COERCE_TO_ZERO=false To my experience, this one should actually only apply on Number properties (int, long, etc), however since a certain late Tomcat 6.0.x version (at least after 6.0.20) it seems to be broken … Read more

JSF/Facelets uses by default UTF-8 to decode HTTP request parameters. GlassFish itself uses by default ISO-8859-1 do decode HTTP request parameters. HTTP request parameters can be parsed and decoded only once and this happens whenever a request parameter is requested by the code for the first time like so request.getParameter(“name”). So, if a request parameter … Read more
This is somewhat subjective, but ala, it boils down to the following: Navigation rules in XML are a maintenance hell. Using navigation rules suggests that the web application in question suffers from the “one URL behind” problem which causes bad user experience (pages are not bookmarkable). Using navigation rules suggests that the web application in … Read more
The value which is passed through the converter is not the option label as you seem to expect, but the option value. The best practice is to not do this in the model side, but in the view side, because the model shouldn’t need to be i18n aware. As to the approach, you’re basically unnecessarily … Read more
Should PARTIAL_STATE_SAVING be set to false? Only when you encounter a general defect related to partial state saving in your webapp which can really not be solved/workarounded the other way. Partial state saving has namely major advantages as to overall performance and memory usage. See also Why JSF saves the state of UI components on … Read more
I had the same problem as described in the question. That’s why I came up with the following solution: Include the primefaces built-in jQuery library (currently 1.4.1) as including an own jQuery library leads to CSS formatting problems. Adding the target=”head” attribute allows for specifying the tag everywhere – e.g. when using templating you not … Read more
It’s been put in the default EL scope during building of the view tree (that’s when all binding attributes — and attributes of tag handlers like JSTL <c:xxx> and JSF <f:xxx> — are being evaluated). It’s being shown by normal EL means during rendering of the view tree. Rendering of the view tree happens after … Read more
