TabNavigator and dynamic tab-styles

Question

I'm trying to change the tab-style skin style based on the content that the parent canvas is being provided.
For example, if the parent canvas (which is being reused everywhere) has a particular property, i'd like my tabNavigator's tabbar to use another skin for the buttons.  I've created a getter in my tabNavigator to access the tab bar.  To which i set the skin style to the class i'd want.  Doesn't work. Is there a simple style that i can set to do this?
I've tried creating a css for every possibility and assign it to tabNavigator with a bindable variable.  But it still displays the default value.  If i put it in the mxml declaration stylename="customskin" it works.  but if i put stylename="{_bindableStyle}", it doesn't work.
In both cases, none of the tabNavigator's children are created until this value is set, so i'm not trying to set a style after the content was created.
I've also tried creating the tabNavigator on creation instead of having it in the mxml declaration, doesn't work either.
Any thing else i can try that i haven't yet?

Hi Frank, thanks for response.
Do you think that somehow in my case there is only one instance of the TF_A ?
Here is relevant settings for my popup containing static region with TF_A
          <af:popup id="pB55" contentDelivery="lazyUncached"
                    popupFetchListener="#{myBean.crudPopupFetchListener}"
                    autoCancel="disabled" childCreation="deferred">
            <af:panelWindow ...>
              <af:region value="#{bindings.TF_A.regionModel}" id="r6"
            </af:panelWindow>
          </af:popup>myBean.crudPopupFetchListener :
   //Task flow activation code (for the TF binding 'active' property  bellow)
   pageFlowScope.put("pB55", "true);
   // code for setting the TF parameters:
   .....and here i setting for TF_A binding from the pageDef:
    <taskFlow id="TF_A"
              taskFlowId="..."
              activation="conditional"
              xmlns="http://xmlns.oracle.com/adf/controller/binding"
              Refresh="ifNeeded" active="#{pageFlowScope.pB55 eq true}">
      <parameters>
      </parameters>
    </taskFlow>
