When I use this code without <p:tab> it works as expected, 

<h:form>
    <p:wizard>
        <p:tab title="Test-1">
            <h:form>
                <p:growl id="msg"/>
                <p:selectOneMenu value="#{studentController.departmentIDgenerate}">
                    <f:selectItems value="#{departmentController.departmentList}" var="deparet" itemLabel="#{deparet.departmentName}" itemValue="#{deparet.departmentId}"/>
                    <p:ajax listener="#{studentController.addMessage}" update="msg"/>
                </p:selectOneMenu>            
            </h:form>
        </p:tab>
        <p:tab title="Test-2">
        </p:tab>
    </p:wizard>
</h:form>

but when I start using <p:tab>, it throws the below exception:

java.lang.StringIndexOutOfBoundsException: String index out of range: -1
    at java.lang.String.substring(String.java:1937)
    at com.sun.faces.renderkit.ServerSideStateHelper.getState(ServerSideStateHelper.java:266)
    at com.sun.faces.renderkit.ResponseStateManagerImpl.getState(ResponseStateManagerImpl.java:100)

How is this caused and how can I solve it?

Lets start by removing the outer h:form (form that wraps the <p:wizard> ) cause you got a nested forms here (which is bad)

  • @MahmoudS, sorry, no idea about what could cause that stacktrace. – Daniel Jul 18 '14 at 22:05
