Question: If I try to use the Message History bean from Spring Integration "int:message-history" when developing a Spring XD module, it fails when try to export the JMX bean. 

I've seen that the naming strategy used is org.springframework.xd.dirt.module.jmx.ModuleObjectNamingStrategy

I already open a ticket for that <https://jira.spring.io/browse/XD-3748>

Is there any workaround for that? Like explicitly use another MBeanExporter and add a different name for the bean?

Answer: 
You shoud try:

```
<div class="hgtinpu errormessage serverside" ng-if="firstnameError && !contact.fname.$touched">{{ firstnameError }}</div>

```
You can use **ng-show** or **ng-hide** directive for that

```
<div class="hgtinpu errormessage" ng-show="contact.fname.$touched  && !contact.fname.$error">
    Message for Touched
</div>
<div class="hgtinpu errormessage" ng-show="contact.fname.$error && !contact.fname.$touched">
    Message Errors
</div>

```
