required fields enforced on cancel with custom controller

I'm trying to build an edit page that contains a save and cancel button. The page has a required field and also has a custom controller.

The problem is that when I press the cancel button to invoke my cancel action, the cancel action is not invoked and instead the page displays an error that I must enter a value for the required field if I have no text in the field.

Is there a way to have this logic bypassed for a cancel action?


Code:
<apex:page controller="NewCaseCommentController" tabStyle="Case">
  <apex:sectionHeader title="Comments" subtitle="Case {!parentCase.CaseNumber}" help="/help/doc/user_ed.jsp—loc=help&target=case_comments_edit.htm&section=Cases"/>
  <apex:form>
    <apex:pageBlock title="Case Comment Edit" mode="edit">
      <apex:pageBlockButtons>
        <apex:commandButton action="{!save}" value="Save"></apex:commandButton>
        <apex:commandButton action="{!cancel}" value="Cancel"></apex:commandButton>
      </apex:pageBlockButtons>
      <apex:pageBlockSection title="Case Details" columns="1">
        <apex:outputField value="{!parentCase.Subject}"/>
        <apex:outputField value="{!parentCase.Description}"/>
      </apex:pageBlockSection>
      <apex:pageBlockSection title="Case Comments" columns="1">
        <apex:pageBlockSectionItem>
          <apex:outputLabel value="Public" for="comment__ispublished" style="text-align:center;"/>
          <apex:inputCheckbox value="{!comment.IsPublished}" id="comment__ispublished"></apex:inputCheckbox>
        </apex:pageBlockSectionItem>
        <apex:pageBlockSectionItem>
          <apex:outputLabel value="Comment" for="comment__commentbody"/>
          <apex:inputField value="{!comment.CommentBody}" required="true" id="comment_commentbody" style="width:450px; height:135px"/>
        </apex:pageBlockSectionItem>
      </apex:pageBlockSection>
    </apex:pageBlock>
  </apex:form>
  <!-- apex:relatedList does not work for CaseComments -->
  <apex:pageBlock title="Case Comments" helpUrl="/help/doc/user_ed.jsp–loc=help&target=case_comments.htm&section=Cases" helpTitle="Case Comments Help">
    <apex:pageBlockList value="{!existingComments}" var="ec">
      <apex:column headerValue="Public" headerStyle="text-align:middle;"><apex:outputField value="{!ec.IsPublished}"/></apex:column>
      <apex:column headerValue="Comment"><b>Created By: &nbsp;<apex:outputLink value="/{!ec.CreatedById}">{!ec.CreatedBy.Name}</apex:outputLink> (<apex:outputField value="{!ec.CreatedDate}"/>)</b><br /><apex:outputField value="{!ec.CommentBody}"/></apex:column>
    </apex:pageBlockList>
  </apex:pageBlock>

</apex:page>
