问题 I have a JSF page that is included in other JSF pages (basically a page header, with common information).

问题 Given the following example: <h:inputText id="foo" size="#{configBean.size}" /> I would like to get the id of the calling component foo in the getter method so that I can return the size from a properties file by a key of foo.length . public int getSize() { String componentId = "foo"; // Hardcoded, but I should be able to get the id somehow int size = variableConfig.getSizeFor(componentId); return size; } How can I achieve this? 回答1: Since JSF 2.0, there's a new implicit EL variable in the

问题 What i want is to open a page in a new tab but don't give focus to the new opened tab. So if i click a few times i can open a few tabs. Just as if i right clicked a link and said open in new tab(I tried that only in chrome and firefox browsers). Do you know is it possible?

问题 Is it possible to use OmniFaces <o:validateAllOrNone> (which is pretty cool ;)) within an <ui:repeat> or <h:dataTable> ? I need a table with each row having an input field column.

The components attribute

问题 I've got a selectOneMenu which has all cities of a state. I've made a sql to bring capital in first place, but i'd like to bold it to make it more visible to who is using it. Is there a way to bold it or to do something else to make more visible just the second option? <h:selectOneMenu value="#{someBean.cityId}"> <f:selectItems value="#{addressBean.stateList}" /> </h:selectOneMenu> 回答1: The HTML <option> element as generated by <f:selectItems> allows for very little fine-grained styling and

问题 Is there a taglib in JSF for inserting the proper application context root in any URL I want, just like the <c:url> tag in JSP does? 回答1: Not exactly that, but all JSF components which refer to an URL resource will already automatically include the proper context path and eventually also the FacesServlet mapping. For example the <h:link>: <h:link value="Link to other page" outcome="otherpage" /> which renders something like (assuming that your context path is /contextname and your

问题 I'm curious how JSF know that I click the button, with some action and it is even possible to call an action listener with a parameter. I can imagine the server notice the state and EL and call the methods. Example 1: <form> <p:commandButton actionListener="{bean.do_something(bean.info)}" /> </form> Example 2: <form> <h:datatable values=... var="myvar"> <h:column> <p:commandButton actionListener="{bean.do_something(myvar.info)}" /> </h:column> </h:datatable> </form> 回答1: During the apply
