Primefaces对话框 - 找不到属性类的Setter

标签： java eclipse jsf primefaces dialog

我想实现Primefaces 3.5 Dialog Component。

我的实施：

<div class="span10">
        <div class="well well-large">

            <h:panelGrid columns="1" cellpadding="5">
                <p:commandButton id="modalDialogButton" value="Modal"
                    onclick="dlg2.show();" type="button" class="btn btn-primary"/>
            </h:panelGrid>

            <p:dialog id="modalDialog" header="Modal Dialog" widgetVar="dlg2"
                modal="true" height="100">
                <h:outputText value="This is a Modal Dialog." />
            </p:dialog>
....

当我启动服务器查看我的页面时，我得到：

我明白了：

<p:commandButton id="modalDialogButton" value="Modal"
                    onclick="dlg2.show();" type="button" class="btn btn-primary"/>

您必须使用styleClass="btn btn-primary"而不是class="btn btn-primary" 

<p:commandButton id="modalDialogButton" value="Modal"
                        onclick="dlg2.show();" type="button" styleClass="btn btn-primary"/>
