Primefaces UI issue with Gallery Film strip

问题

I am implementing a gallery using PrimeFaces with the component p:galleria, everything works as expected but the footer (Film Strip) is shown twice.

By the way, if I close and then reopen the modal dialog which contains the gallery the Film Strip displays correctly.

More Information:

• The gallery is contained in a modal dialog
• PrimeFaces version: 5.3
• Browsers: Chrome and IE

Any help is appreciated

回答1:

I have resolved this behavior with the next workaround...

I had to open the external dialog using onclick() event instead of oncomplete()

Greetings!!!!

回答2:

I already have onclick but the filmstrip still gets doubled.

A working workaround for me is to update the galleria when the dialog is shown, e.g.

<p:commandLink onclick="PF('popup').show();" update="galleria"/>
<p:dialog id="popup">
    <p:galleria id="galleria"/>
</p:dialog>
