How to use ZK getFellow() method ?

Question

Hi,

I am passing a bunch of tabs from a zul file to a java file like so:

tabs.zul

<tabs>
  <tab id="tab1" label="Tab1"> </tab>
  <tab id="tab2" label="Tab2"> </tab>
</tabs>
<zscript>
testTabs = new TestTabs();
Tab[] tabs = {tab1, tab2}
testTabs.registerTabs(tabs)

TestTabs.java

public class TestTabs {
....
private HashMap<String,Tab> tabMap;

  void registerTabs (Tab[] tabs) {
    this.tabMap = new HashMap<String,Tab>();
    for (Tab t: tabs) {
      this.tabMap.put(t.getId(),t);
    }
  }

 if(condition) {
   tabMap.get("tab1".setVisible(true);
   tabMap.get("tab2").setVisible(true);
 }  

}

Now, I guess using Hashmaps to access a tab is a roundabout way. Using a getFellow(String id) method to access a tab would be much simpler, right ? But, I am not sure how to implement that. Can someone help me with this?

Thanks, Sony
