Disturbing observation - why is it needlessly executing code??
I have stumbled onto something potentially disturbing where a method call in my xhtml file, showGroupRemoveColumn() in my example below, is redundantly executing the method in the underlying EntityHome class as can be seen in the log snippet below.
Can anyone explain this??
Here's the relevant section from my xhtml file:
<s:div id="relatedGroups" rendered="#{not empty ticket.groups}">
<h:form id="relatedGroupsForm" styleClass="edit">
<rich:panel style="background-color: #DAFF7F;">
<f:facet name="header">Group Relationships</f:facet>
<rich:dataTable id="groupList" var="group" value="#{ticket.groups}">
<rich:column width="4%">
<f:facet name="header">Group ID</f:facet>
#{group.id}
</rich:column>
<rich:column width="40%">
<f:facet name="header">Group Name</f:facet>
<s:link view="/GroupEdit.xhtml"
value="#{group.name}"
id="edit">
<f:param name="groupId" value="#{group.id}"/>
<f:param name="conversationPropagation" value="none"/>
</s:link>
</rich:column>
<rich:column width="1%" rendered="#{ticketHome.showGroupRemoveColumn()}">
<f:facet name="header">Remove From Group</f:facet>
<h:commandLink action="#{ticketHome.removeTicketFromGroup(group.id)}"
onclick="if (!confirm('Are you sure you want to remove this Ticket from Group [ #{group.name} ] ?')) return false">
<h:graphicImage value="/img/b_delete.png" title="Remove this Ticket from Group [ #{group.name} ]"/>
</h:commandLink>
</rich:column>
</rich:dataTable>
</rich:panel>
</h:form>
</s:div>Here's the relevant method from my EntityHome class:
public Boolean showGroupRemoveColumn() {
Integer ticketId = getInstance().getId();
Integer groupCount = getInstance().getGroups().size();
log.info("%%%%%%%%%%%%%%%%% showGroupRemoveColumn() %%%%%%%%%%%%%%%%%: " + groupCount + " --- " + ticketId);
return (groupCount > 1);
}Here's the relevant section of output from my log file:
It starts out with the burst of 10 calls to the method, then it fires off another 28 calls to it shortly afterward. I have observed that the second burst is always 7 times the groupCount value (for example: if groupCount is 7 there would be 49 log entries in the second chunk of them)
