PrimeFaces: how to override CSS class

问题

When a button is created, the class ui-corner-all is always applied. I tried the following:

<p:commandButton id="like" styleClass="ui-corner-right" />

but it didn't work. On Firebug, I saw both ui-corner-all and ui-corner-right:

<div id="form1:like" type="button" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-icon-left ui-corner-right">

UPDATE 1:

Following the hint from JMelnik, I finally succeeded to change the style of ui-corner-all to ui-corner-right by adding the following script:

<style type="text/css">
    #myForm\:likeButton .ui-corner-all {
        border-radius: 6px 0px 0px 6px !important;
    }
</style>

and wrap the <p:commandButton> inside <h:panelGroup> as following:

<h:form id="myForm">
    <h:panelGroup id="likeButton">
        <p:commandButton />
    <h:panelGroup>
</h:form>

UPDATE 2:

Thanks to BalusC's suggestion, the following solution should be better:

<style type="text/css">
    .likeButton .ui-corner-all {
        border-radius: 6px 0px 0px 6px !important;
    }
</style>  

<h:panelGroup styleClass="likeButton">
    <p:commandButton />
<h:panelGroup>

Best regards,

Use a standard CSS override way.

Include a *.css in your page, where you redefine ui-corner-all and ui-corner-right classes.

.ui-corner-all {
    //ovverides to nothing, you can also define any properties you want here
}

.ui-corner-right {
    //define properties  which would override unwanted behaviour
}

You can also apply additional css class which would override undesired properties.
