The problem is as follows: I need to put checkbox in Primefaces p:tab title via facet, but when I click the checkbox I don't want tab to open.

Here is a code snippet.

```
<p:accordionPanel multiple="true" activeIndex="">               
    <p:tab rendered="#{condition}">
        <f:facet name="title">
            <div>
                <h:selectBooleanCheckbox styleClass="simple-checkbox" value="#{someValue}" >
                    <p:ajax event="click" process="@this"
                            action="#{some action}"
                            update="some elements" global="false" />
                </h:selectBooleanCheckbox>
                <h:outputText value="some text" />
            </div>
        </f:facet>
        Tab Body
    </p:tab>
</p:accordionPanel>     

```
