Unable to render Error Message <h:message> on JSF page
I have a textfield on jsf page , the onblur event of textfield calls a backing bean method . This method in certain situation catches Exception and calls FacesContext to render error message on jsf page. The problem is message doesnt get render on to jsf page inspite of having h:message tag.
Here is the snippet
JSF page
<h:panelGrid columns="3" styleClass="detail" columnClasses="label" >
<h:outputLabel><h:outputText value="Property Tag" /> </h:outputLabel>
<h:inputText id="propertyTag" value="#{deviceBean.tagNumber}" >
<a4j:support action="#{deviceBean.loadAssetDetails}" event="onblur" reRender="mypanel" />
</h:inputText>
<h:message id="propertyTagError" for="propertyTag" styleClass="errorMessage" />
</h:panelGrid>
Backing Bean
public String loadAssetDetails() {
try{
namsAsset = deviceManager.getAssetDetails(sourceSystem, tagNumber); //calls database
}catch(RuntimeException re){
if (re.getMessage().contains("No Asset found")){
System.out.println("Inside Bean No Asset Exception");
FacesContext.getCurrentInstance().addMessage("deviceForm:propertyTag", new FacesMessage(FacesMessage.SEVERITY_ERROR, re.getMessage(), re.getMessage()));
return null;
}
}
The log file prints the messages inside the catch block. But it doesnt get render on JSF page. Any pointers/suggestions will be highly appreciated
