We ran into an issue on 
http://myvoicetouch.com/voicetouch/web/zlogin/registerUser.xhtml
where basically, we would fill in the email and then tab to the company alias and start typing and the email would CLEAR.  I am not sure why this started happening.  We have another site on a different version of seam with no problems.  Has anyone seen anything like this before?
Here is the code.....(it came right from the seam booking example)..any ideas?
                              <div class="entry">
                                   <s:decorate id="nameDecorate" template="errorTemplate.xhtml">
                                        <ui:define name="label">Email:</ui:define>
                                        <h:inputText id="name" value="#{webUser.email}" required="true">
                                    <a:support event="onblur" reRender="nameDecorate"/>
                                </h:inputText>
                                   </s:decorate>
                              </div>
                              
                              <div class="entry">
                                   <s:decorate id="aliasDecorate" template="errorTemplate.xhtml">
                                        <ui:define name="label">Company Alias:</ui:define>
                                        <h:inputText id="alias" value="#{webUser.companyAlias}" required="true">
                                    <a:support event="onblur" reRender="aliasDecorate"/>
                                </h:inputText>
                                   </s:decorate>
                              </div>finally, figured it out.  For any one else, it is just needing to add ajaxSingle="true" AND bypassUpdates="true"
hope that helps someone.
later,
