Well, this can be a common usecase across apps to open tabs dynamically at runtime based on the request.

Well, in order to achieve this you can have a parent container, lets say a panelTab component.Inside panelTab , u can have a showDetailItem inside an af:foreach or an af:iterator binded to a bean static list which will have as many show detail items as you wish to be shown.

something like this.

private static List = { new showDetailItem("1"),new ShowDetailItem("2") ...};

now in the backing bean you can have a method that takes care of rendering and disclosing an specific tab based on the index.

public void openMyTab(){

List<MyItems> list = refToParentContainer.getChildren();
int indexOfTabToBeOpened = //Write a method that will compute the tab index of the next //tab.

list.get(index).setRendered(true);
list.get(index).setDisclosed(true);

similarly you can set other properties too.

}

Else, instead of having af:foreach/iterator iterating through the SD items , you can go for static SDs in the page with render property set to false and then you can follow the same approach to render/disclose it at runtime.
