Breadcrumb returning always to first stacked detail group

Question

Hi,
Inside a dummy view group (say Dummy1) I have implemented stacked detail groups containing table-forms. The main page looks like below when I select Dummy1
Dummy1|Dummy2
Tab1|Tab2|Tab3|Tab4
After I select let's say Tab3, the corresponding table appears and afterwards I select "Details" for a row in that table which leads me to the corresponding form.
That form contains the following Breadcrump
Modify Dummy1 >
When I select the hyperlink, the breadcrumb returns me back to Dummy1 but to Tab1 is selected instead of Tab3. How can I make it return to Dummy1 but have Tab3 selected?
TIA

To preserve the selected tab, you will need to save the state of the showOneTab element using the binding property in a session-scoped managed bean.
Here are the steps:
- In the generated page, select the af:showOneTab element
- go to the property inspector, click on the Binding property, and click on the three dots button that appears. This launches a dialog to bind the binding property to a managed bean.
- In the dialog, click the New button to create a new managed bean. Name it soemthing like MyPageState, and set the class to something like view.MyPageState. Set the Scope to "session" and leave the checkbox "generate class if it does not exist" checked. Click OK
- now click the New button at the right of the property name, and enter a property name like "mySelectOneTab".
- Click OK twice
- Run the page, you will see that the tab state is now preserved when you navigate back to the the page using the breadcrumb.
- To preserve this post-generation change after regeneration, you need to create a custom template for the selectOneTab, and move the generated bean definition to a non-generated faces-config.xml, for example faces-config-custom.xml. If you create such an additional faces-config-custom.xml, make sure you add the name to the javax.faces.CONFIG_FILES context param in web.xml
