When I am using the onkeyup event the focus jumps to the done button in the form instead of staying on the h:inputText box, below is the applicable code.

 <h:form enctype="multipart/form-data" id="upload">
 <h:panelGrid columns="2">
 <h:outputText value="Description: " id="description" />
 <h:inputText value="#{OrderView.uploadDescription}" id="uploadDescription" immediate="true" >
 <a4j:support event="onkeyup" reRender="upload" />
 </h:inputText>
 </h:panelGrid>
 <rich:fileUpload id="upload"
 immediateUpload="true" fileUploadListener="#{OrderView.addUpload}"
 disabled="#{fn:length(OrderView.uploadDescription) lt 10}">
 </rich:fileUpload>
 <span id="submitbutton"><h:commandButton value="Done"
 action="success" styleClass="button" /> </span>
 </h:form>
