Ones who are familiar with OmniFaces only need to keep in mind that you can't use a SelectItemsConverter as there's no means of a anymore. You can just attach a Converter to the the usual way. How about complex objects as item values? Oh, I'm using xmlns:a="" instead of xmlns:p as shown in the JSF documentation and Java EE 7 tutorial, for the simple reason that I'd like to keep PrimeFaces happy ) The a stands here just for "attribute". For a in depth explanation on properly using JSTL in JSF, see also JSTL in JSF2 Facelets… makes sense? I created a quick attempt like below: class Bean ". Passthrough elements and attributes to rescueīut, since JSF 2.2, which came with new support for passthrough elements and attribtues, it's technically possible to override the name attribute when you set it as a passthrough attribute on a passthrough element. Currently, there's ongoing discussion to adopt their approach in the standard JSF component set for the upcoming JSF 2.3. Fortunately a lot of component libraries offer a solution to this such as Tomahawk and PrimeFaces, which support a new layout attribute value of "spread" and an additional component to represent a single button (the resp. This works only if the last radio button of the group is being selected as they are in JSF side basically all processed individually instead of in a group and thus each radio button of the iteration would override the model value of the previous one. You could throw in some JavaScript to get the unselection to work anyway, but then there's the problem of setting the submitted value in the model. The technical problem is, they don't share the same name attribute in generated HTML output. When you select one radio button, then the others won't be unselected. Ones who attempted to create multiple components with each a single value using an or even, likely already noticed it: the radio buttons are not grouped. There was no way to achieve a custom layout without customizing the renderer and/or introducing a new component. If you loathe HTML tables for non-tabular data, then you could instead of the render multiple es in a loop based on an altered model. In JSF, the only components which by default render unnecessarily a HTML this way are the and. In HTML, particularly since HTML5 wherein the world is made more aware of semantic HTML, tables are discouraged for other purposes than tabular data.
