Given the following Portlet Code: ArrayList nameList = new ArrayList(); nameList.add("Willi Willisch"); nameList.add("Seppi Seppisch"); renderRequest.setAttribute("names", nameList); And the following JSP Code: <c:forEach var="aName" items="${names}"> <tr> <td>${aName} </td> </tr> </c:forEach> Prints out: ${aName} ${aName} I don't have any clue why a $(aName) isn't evaluated. The forEach loops works, because ${aName} is printed out twice .... <c:out value="${aName}"/> works!! But shouldn't ${aName} work aswell? Thus, "EL in template text" doesn't work? That can have one or more of the

My JSF custom component code: <composite:interface name="translation"> <composite:attribute name="fieldName"/> <composite:attribute name="required" default="true" /> </composite:interface> <composite:implementation> <h:inputText required="#{cc.attrs.required}" requiredMessage="Please enter #{cc.attrs.fieldName} in english"/> </composite:implementation> This works fine if I specify the required attribute as follows: <comp:translation fieldName="myTranslation" required="true" /> But does not work if I give EL in required attribute of my composite component: <comp:translation fieldName=

I am using Thymeleaf 3 within a Spring Boot application. Currently I am in a situation where I want to use a message expression inside an EL expression (Spring EL). First use case: trim the message data:title="${#{message.key}.trim()} Second use case: conditionally create an attribute with a message as its value data:title="${condition ? #{message.key} : ''} Both examples will produce a syntax error, because #{ is not an allowed start of an expression. Any ideas how to achieve what I want? In both cases you'll want to use the #messages utility object. data:title="${#messages.msg('key').trim()}

I'm using spring MVC and I want to access to my Employe's roles from my jsp file but i have this error.

I've been using this.$el all over my backbone app like so: render: function() { this.$el.html(this.template); }, then I saw code online that uses: render: function() { var dict = this.model.toJSON(); var html = this.template(dict); $(this.el).append(html); } What is the difference between the two? If you call $(this.el), your just keep executing the jquery selector to get the same jquery object. '$el' is the cached version of $(this.el) 来源： https://stackoverflow.com/questions/19013531/backbone-this-el-vs-this-el

I'm working with JSF and PrimeFaces, but I need to get the value of the id of a component. Because I'm building dinamycally panels with diferent id, to show a the panel I need to compare if is the current panel, then show it. For example if I've the next panel <p:outputPanel id="#{bean.getID}" autoUpdate="true" renderer=#{@this.id == bean.currentPanel} > </p:outputPanel> And Bean public class Bean(){ private int numberPanels =0; private int currentPanel = 0; public int getID(){ //...a process that return different ID } // getter's and setters } Obviously, @this.id doesn't work. So, how to get

I would like to add a simple template language to my application based on Seam / JSF to let the users compose their own email. Since I don't want to create a new parser, I would like to use the Unified Expression Language setting the context all by myself. How can I do that? If you're sitting inside the JSF context, then just use Application#evaluateExpressionGet() to programmatically evaluate a string containing EL expressions. String unevaluatedString = convertMailTemplateToStringSomehow(); FacesContext context = FacesContext.getCurrentInstance(); String evaluatedString = context

Can I access the expression string of a ValueExpression passed as attribute value to my taglib component? My goal is to programmatically derive missing attribute values from it. In this case I'm trying to avoid having to repeat an attribute as a literal. now: <a:columnText title="name" value="#{entity.name}" sortBy="entity.name" /> desired: <a:columnText title="name" value="#{entity.name}" /> -taglib.xml <tag> <tag-name>columnText</tag-name> <source>column-text.xhtml</source> <attribute> <name>value</name> <required>true</required> </attribute> <attribute> <name>title</name> <required>false<
