Here are more code
<h:panelGrid columns="2" style="margin-bottom:10px" cellpadding="5">
<p:outputLabel for="selectone" value="Upload :" />
<p:selectOneRadio id="selectone"
value="#{tweetDistributionManagedBean.tweetType}">
<f:selectItem itemLabel="Group Tweets" itemValue="GT" />
<f:selectItem itemLabel="Event Tweets" itemValue="ET" />
<f:selectItem itemLabel="Suprachar Tweets" itemValue="ST" />
<p:ajax event="click"
listener="#{tweetDistributionManagedBean.renderUploadPanel}"
update="gtid" process="#form" global="false" />
</p:selectOneRadio>
</h:panelGrid>
and Java bean method
public void renderUploadPanel(final SelectEvent event) {
String selecteValues = (String) event.getObject();
visibleGTFlag = true;
}

Answer 1

Moist likely the 'SelectEvent' is not an event that extends AjaxBehaviourEvent . This can happen if you import the wrong class type. Try this
public void renderUploadPanel(AjaxBehaviorEvent event) {
System.out.println(tweetType);
visibleGTFlag = true;
}

Answer 2

You can try to use the event "ValueChangeEvent", look my example:
public void renderUploadPanel(ValueChangeEvent event) {
String selecteValues = event.getNewValue().toString();
visibleGTFlag = true;
}
