问题 For my project i want to implement a combobox with h:selectOneMenu . I read many posts about how to handle the selectOneMenu properly and how to implement a custom converter. The combobox shall store the ID ( Long ) from a different DB Table (named fk_ID) for which a constrain is in place. So far everything seems to function as planned. Now to my problem: The column fk_ID is optional, so the first option in the combobox is a f:selectItem with no value labeled "choose ...". When I save the

问题 I'm working with JSF 2.0 I have a form in my admin section where I am going to select some users in a list. The form (selectusers.xhtml) is adding these users to a list in a bean (SelectUsers.java). After I have selected some user(s), I will pass the list of the user(s) from SelectUsers.java to another bean (AddAddressBean.java) and continue add information in another form (addadress.xhtml) which set other properties related to AddAddressBean for each user. I do not know how to implement it.

问题 I'm creating simple example on JSF. It's small Login application. My problem is duplicate error messages on my page: I have two h:message (for username and password) tags and one h:messages (global messages) on my page: <h:form id="loginForm"> <h:panelGrid columns="3"> <h:outputText value="Username" /> <h:inputText id="username" value="#{loginBean.username}" required="true" requiredMessage="Please enter your username" /> <h:message for="username" errorClass="errorMessage" /> <!-- Message for

问题 I have a table with 2 selectOneMenu components. I would like that once a record was chosen in the first selectOneMenu component it will update the other selectOneMenu with Ajax in the same row. My table: <p:dataTable value="#{myBean.myInfo}" var="myInfo"> <p:column> <f:facet name="header">Group</f:facet> <h:selectOneMenu value="#{myInfo.myInfoType.code}"> <f:selectItems value="#{myBean.myList}" /> <f:ajax event="change" execute="@this" listener="#{myBean.refershNames}" render="myNames"/> </h

问题 Currently we're trying to move to JSF 2.0 from JSF 1.2 and one of the problem we've faced is that it's impossible to rerender part of the page that contains form. Like this (rerender outerDiv or forms themselves): <h:panelGroup id="outerDiv"> <h:form id="form1">...</h:form> <h:form id="form2">...</h:form> </h:panelGroup> I mean that if i update outerDiv everything is updated but the form (or forms) itself becomes broken and behaves strangely, at least ajax calls either don't work when first

问题 I have added a common JAR to my project. The jar looks something like...

问题 I reviewed my code lot of times and didnt find questions about it. I have a problem with p:commandButton rendered property. The p:commandButton is allways displayed even if the getter method returns false. That happens after an ajax update. I have a p:selectOneMenu with a p:ajax event="change" that sets a MB and updates a p:commandButton (with a rendered property based on a boolean getter) and two other components: a second p:selectOneMenu and a p:outputLabel. The second p:selectOneMenu and
