The tr:statusIndicator is used to display a status when an Trinidad Ajax
call is taking place. It just shows a status when the request is in-flight.
I check one of my applications and this works fine:
<tr:panelHorizontalLayout>
<tr:spacer height="1" width="135"/>
<tr:commandButton id="continueButton"
text="#{bundle.continue_label}"
styleClass="myButton"
action="#{someActionBacking.continueAction}"
partialSubmit="true"/>
<tr:statusIndicator>
<f:facet name="busy">
<tr:image source="///images/pgsIndAnm.gif"
shortDesc="#{bundle.processing_label}"
styleClass="someStatus"/>
</f:facet>
</tr:statusIndicator>
</tr:panelHorizontalLayout>
tr:status doesn't require any partialTrigger attribute to work.
>From what I understand the event is occurring on the server. That is that
some component is changing the contents of the text and Hakon wants to
display the updated text. Depending on how and when the text is updated, a
tr:poll component would poll the server for the change. If the change occurs
as part of another user-initiated event, then a partialTrigger attribute
could be used on the outputText, but the tr:statusIndicator wouldn't be
required either.
