How to refresh inputboxes in JSF after ajax submit command? - jsf

Question

I have an inputText and an inputTextArea in JSF (shown below) that I carry out an ajax action on. However, after my ajax event, the values remain in the input boxes. Is there a simple way to refresh these text boxes after the commandButton is involked? Thanks.
<table>
<tr>
<td><div class="white"><H2>Comments</H2></div>
<h:inputText class="inputboxes" id="username"
value="#{commentBean.comment.commentname}" size="20">
</h:inputText><br/><br/>
<h:inputTextarea rows="5" cols="55" id="comment" class="inputbox" value="#{commentBean.comment.commentText}"
size="20" /></td>
</tr>
<tr>
<td></td>
<td><h:commandButton id="update"
action="#{commentBean.addComment(searchBean.companyId)}" class="myButton2" value="Add Comment" >
<f:ajax execute="#form" render=":results"/>
</h:commandButton></td>
</tr>
</table>
</h:form>
<h:form id="results">
<table>
<tr>
<td>
<h:dataTable value="#{commentBean.viewComments(searchBean.companyId)}" var="c">
<h:column>
<div class="commentsbox">#{c.commentText}</div>
</h:column>
<h:column>
<div class="boldfont">#{c.commentdate}</div>
</h:column>
<td><h:column>
<div class="commentname">#{c.commentname}</div>
</h:column>
</td>
</h:dataTable>
</td>
</tr>
</table>

In your view :
<f:ajax execute="#this" render=":results, username, comment"/>
In your backing bean, in the addComment() method :
comment.setCommentname(null);
comment.setCommentText(null);
or simply (I guess only)
comment = null;
