modify styleClass of a p:commandButton conditionally in primefaces

Question

I would like to modify the style class of ap:commandButton in primefaces conditionally, like this:

 <p:commandButton  value="#{file.name}"  styleClass="#{file.statut == 0 ? 'normalClass' : 'strikeThroughClass'}">

It works OK for the normal

outputText 

but does not seem to work on the

 p:commandButton  

Could you give me a hand ?

Answer 1

I used

 <h:commandButton styleClass="#{dmFile.statut == 0 ? 'normalClass' : 'strikeThroughClass'}     ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only"  value="#{dmFile.name}">
</h:commandButton>

And in css

.ui-button.strikeThroughClass{
 text-decoration:line-through!important;
}
