Helllo,

Bind <b>selectedTab</b> property of TabStrib to context attribute. Then you can read ID of currently selected via reading context attribute and even change currently selected tab simply by assigning value to attribute.

What does it means by "name of UI element event parameter"? Can you show us an example?

Thank you.

Some UI element events have parameters, you can find their names and types in the Javadoc of the mappingOf<event>() methods.

When we click on a Tab, we would like to fire out to another view. Attached are coding:

public static void wdDoModifyView(IPrivateRatingMainView wdThis, IPrivateRatingMainView.IContextNode wdContext,

com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)

{

IWDTabStrip iwdTabStrip = (IWDTabStrip)view.getElement("tsRatingMain");

String selectedTab = iwdTabStrip.getSelectedTab();

crrsLogger.info("selectedTab " + selectedTab);

wdContext.currentContextElement().setQualitativeTab(selectedTab);

}

public void onActionRatingMode(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String mode )

{

String selectedTab = wdContext.currentContextElement().getQualitativeTab();

crrsLogger.info("onActionRatingMode selectedTab " + selectedTab);

if (selectedTab.equals("tabQualitative"))

{

crrsLogger.info("Execute Fire Plug");

wdThis.wdFirePlugToLargeCorp();

}

}

But, the problem is, "wdModifyView" is always called first before "onActionRatingMode". So, the value of selectedTab is always refer to the previously called tab.

Any suggestion is kind appreciated.

How to access the selected tab ID in an action event handler after switching to a new tab:

1. Add parameter, e.g. "selectedTab", to your action event handler.

2. In wdDoModifyView(), declare an event parameter mapping for the parameter "tab" of event IWDTabStrip.onSelect:

if (firstTime)
{
  IWDTabStrip tabstrip = (IWDTabStrip)
    view.getElement(<tabstripID>);
  tabstrip.mappingOfOnSelect().addSourceMapping(
    "tab", /* name of UI element event parameter */
    "selectedTab" /* name of action handler parameter */
  );
}

Then you get the ID of the new selected tab in your action event handler through parameter "selectedTab".

You mean the ID of the currently selected tab?

See:

IWDTabStrip.getSelectedTab()

or if you need access in an event handler: Bind the selectedTab property and ask the view context for the current value.
