问题
I checked the z-index, but the Dialog z-index is higher than the div of overlay. It was to be correct.
In the showcase works correctly.
Could you help me with this problem?
回答1:
Set appendToBody = true and your problem will go away - but be careful to have a form inside if you do some server-side processing. More info when you post more info!
回答2:
For primefaces 5.1 you can use appendTo="@(body)"
