Primefaces p:confirmDialog inside tabView

I now have problem with using confirmDialog inside tabView. Here is my confirmDialog

<p:confirmDialog global="true" showEffect="fade" hideEffect="explode">
    <h:form>
        <p:commandButton value="Yes" type="button"
            styleClass="ui-confirmdialog-yes" icon="ui-icon-check" />
        <p:commandButton value="No" type="button"
            styleClass="ui-confirmdialog-no" icon="ui-icon-close" />
    </h:form>
</p:confirmDialog>

In the 1st tabView, I have a button with confirmation

<p:commandButton value="Import" icon="ui-icon-arrowrefresh-1-w"
    update=":form:growl">
    <p:confirm header="Confirmation" message="Are you sure?" />
</p:commandButton>

In the 2nd tabView, I have exactly that button.

And now my problem is: In the 1st tab, my confirmDialog have full text as I want: header and message, however in the 2nd tab, the header and message all become "null". Only button yes and no of confirmDialog still work. I don't know what is happening, please help me, how to make confirmDialog display full content in all tabView

Solution

It seems to work ok for me. See example below

<?xml version="1.0" encoding="UTF-8"?>

</h:head>
<h:body>
    <h3>This is a JSF view.</h3>
    <h:form id="form">
        <p:confirmDialog global="true" showEffect="fade" hideEffect="explode">
            <h:form>
                <p:commandButton value="Yes" type="button"
                    styleClass="ui-confirmdialog-yes" icon="ui-icon-check" />
                <p:commandButton value="No" type="button"
                    styleClass="ui-confirmdialog-no" icon="ui-icon-close" />
            </h:form>
        </p:confirmDialog>

        <p:tabView id="tabView">

            <p:tab id="tab1" title="Tab one ">
                <p:commandButton value="Import" icon="ui-icon-arrowrefresh-1-w"
                    update=":form">
                    <p:confirm header="Confirmation" message="Are you sure?" />
                </p:commandButton>
            </p:tab>

            <p:tab id="tab2" title="Tab two">
                <p:commandButton value="Import" icon="ui-icon-arrowrefresh-1-w"
                    update=":form">
                    <p:confirm header="Confirmation" message="Are you sure?" />
                </p:commandButton>
            </p:tab>


        </p:tabView>
    </h:form>
</h:body>
</html>

Output:

Tab 1 with dialog box Tab 2 with dialog box

It would be good if you post your full xhtml code so we can see what could be the problem there.
