PanelBox Disclosure icon is calling only checkbox value change listener

Question

Hi
I have a page fragment, where i have a switcher and showing different facets based on condition, in my second facet i have a panel box which has a panel group layout which has one selectbooleancheckbox and one outputtext.
When i click on the check box, i need to make the outputtext invisible, this i am trying to achieve thru valuchangelistener. I am able to make it visible and invisible based on the value. The same way i have multiple panel boxes, the issue here is when i try to undisclose the panel box, or disclose the other panel boxes, the valuechangeevent is getting called.
I am using pageFlowScope for the bean and it has so many other value change events for select one choices, but only for the first time the check box value change events are getting called. I can achieve the same using java script, but i am trying to avoid using js.
I am using JDev 11.1.2.1.0 and the page fragment is in task flow, where i used the task flow as a region in a jspx page. Thanks.

I think you're not dealing correctly with the default value of the selectOneMany. Do not let the submitted value be implicit but rather tells exactly what it should be. To manage that add a "noSelection" selectItem and return this value instead of null in from getImageType()
Thus you might have:
<h:selectOneMenu id="selectionid"
value="#{tagGeneratorTagView.imageType}" valueChangeListener="#{imageHandler.changeImageType}"
onchange="submit();">
  <f:selectItem itemValue="NOVALUE" itemLabel="No value selected"/>
  <f:selectItem .... your items ..
</h:selectOneMenu>And in getImageType
public String getImageType()
   //this is not a good example. the default value should be inject
  if(null==imageType)
    return "NOVALUE"
  return imageType
}
