Autocomplete display problem

[hfcprime]

Using 3.0M3 snapshot (from 7/12), the autocomplete control doesn't display correctly. It has no width dimension, appears in the following code after its label, but on top of the label and control to its right. It still works correctly, just won't display correctly. (Mojarra 2.04, TC 7.014). This displayed correctly with earlier Prime 3.0 releases.

<h:panelGrid columns="4" cellspacing="6"
columnClasses="lftcol,rtcol,lftcol,rtcol">
<h:outputLabel for="ldapId"><b>LDAP Id:</b></h:outputLabel>
<p:autoComplete forceSelection="true" id="ldapId" value="#{ldapLoc.ldapId}"
queryDelay="150" completeMethod="#{ldapLoc.complete}"/>
<h:outputLabel for="location"><b>Location:</b></h:outputLabel>
<h:selectOneMenu id="location" value="#{ldapLoc.locationId}">
<f:selectItem itemLabel="Select Location" itemValue="" />
<f:selectItems value="#{ldapLoc.locations}" />
</h:selectOneMenu>
</h:panelGrid>
