由 左心房为你撑大大i 提交于 2019-11-26 09:18:24
问题 I\'m using JSF with facelets and I need to get the request and session parameters inside the JSF page. In JSP pages I got this parameter like that: \"${requestScope.paramName}\" or \"${sessionScope.paramName}\" . But now after using JSF there are only beans and you can\'t get any value except bean attributes. NOTE: The session attributes what I need is auto filled using acegi security so I can\'t get any access to them. So what to do now? 回答1: You can get a request parameter id using the

问题 I\'m trying to assign an id to a component inside a <ui:repeat> like that: <ui:repeat value=\"#{bean.columns}\" var=\"column\"> <h:panelGroup layout=\"block\" id=\"column_#{column.id}\" styleClass=\"#{column.id} dashboard_column\"> The thing is that #{column.id} value is being placed properly inside the styleClass value but its not being set inside the id attribute.

How to create a custom Facelets tag?

由 爱⌒轻易说出口 提交于 2019-11-26 06:48:11
问题 I am using JSF 2.0. I created custom JSTL tags with tagfiles and that were working fine in JSP. But I want to use custom JSTL tags in Facelets too. Is it possible to create tagfiles in Facelets or not? 回答1: "Custom JSTL tags" makes honestly no sense. This term is utterly meaningless. JSTL is already a taglib at its own. Please carefully read the introductory paragraphs of our JSTL wiki page to learn what JSTL really is. You perhaps actually meant "Custom JSP tags". Of course they would not

由 ⅰ亾dé卋堺 提交于 2019-11-26 04:50:50
I have made a lot of progress in converting my JSF applications to book-markable pages, but I am wondering if I am doing it the right way.
