这是我的表
假设我在表中有10个用户并且我点击用户ID 2进行编辑，bootsfaces模式将表中的最后一个用户显示为模态;这是用户ID 10.
<div class="tab-pane fade" id="add9">
<h:form class="form-horizontal" >
<h3 class="title-section title-bar-high mb-40">System User Report</h3>
<div class="orders-info">
<div class="table-responsive">
<b:dataTable class="table table-bordered table-responsive" var="user" value="#{userBean.findsAll()}" onorder="console.log('order');" onselect="ajax:userBean.editUser(user)" onpage="console.log('page');" >
<h:column>
<f:facet name="header">Sr. No.</f:facet>
<h:outputText value="#{user.id}" />
</h:column>
<h:column>
<f:facet name="header">Name</f:facet>
<h:outputText value="#{user.userName}" />
</h:column>
<h:column>
<f:facet name="header">Status</f:facet>

</h:column>

</h:column>
<h:column>
<f:facet name="header">Date</f:facet>
<h:outputText value="#{user.userDate}" />
</h:column>
<h:column>
<f:facet name="header">Action</f:facet>
<b:commandButton iconAwesome="pencil" look="link" action="#{userBean.editUser(user)}" onclick="$('.modalPseudoClass').modal();return false;">
<f:ajax execute="#{userBean.editUser(user)}" render="@none" />
</b:commandButton>
<b:commandButton action="#{userBean.deleteUser(user)}" onclick="return confirm('You Are About You Delete This User!')" iconAwesome="trash" look="link">
</b:commandButton>
</h:column>
</b:dataTable>
</div>
</div>
</h:form>
</div>
这是我的bean控制器
public class UserBean implements Serializable {
@EJB
private UserFacade userFacade;
private User user;
public UserBean() {
user = new User();
}
public UserFacade getUserFacade() {
return userFacade;
}
public void setUserFacade(UserFacade userFacade) {
this.userFacade = userFacade;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public void deleteUser(User user){
userFacade.remove(user);
}
public void editUser(User user){
this.user = user;
}
public void editUser(){
userFacade.edit(this.getUser());
user = new User();
}
}
这是我的bootsfaces模式

答案 0 :(得分：0)
当用户选择行时，您需要更新模态的内容。您知道，数据表和模态是同一个XHTML文件的一部分，因此它们同时呈现。当然，这太早了，所以如果没有更新，模态会显示错误的用户。
顺便说一句，我认为将user重命名为selectedUser，将其初始化为null，并仅在selectedUser为editUser()时才呈现模态的内容是一个好主意。不是空的。这样，你会注意到什么时候出错了。此外，更少的HTML代码将发送到客户端。
与您的问题没有直接关系：您的代码段多次调用if (context.Request.Method == "OPTIONS")
{
context.Response.Headers.Add("Access-Control-Allow-Origin", new[] { (string)context.Request.Headers["Origin"] });
context.Response.Headers.Add("Access-Control-Allow-Headers", new[] { "Origin, X-Requested-With, Content-Type, Accept, Authorization" });
context.Response.Headers.Add("Access-Control-Allow-Methods", new[] { "GET, POST, PUT, DELETE, OPTIONS" });
context.Response.Headers.Add("Access-Control-Allow-Credentials", new[] { "true" });
}
。你可能想做一些家务。
