How is this INavCodeConstants Interface working ?

[Former Member]

Hi All,

I have been working with SAP Standard SCA IS-SRS.SCA.

There are two views which need to be modified by mapping the input field to a String field.

When I saw the code of first view: GrItemsOverviewView it's navigating to the second view: GrItemDetailView on click of the copy button at GrItemsOverviewView .

The code in GrItemsOverviewView is:

public void onActionCopyData(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
    //@@begin onActionCopyData(ServerEvent)
	wdThis.wdGetGrAppCompController().invalidateGrItemsTable();
	wdThis.wdGetGrAppCompController().clearCurrentItemNumber();
	wdThis.wdFirePlugItemsOverviewDone(INavCodeConstants.NAV_CODE_COPY);
    //@@end
  }

The Interface INavCodeConstants:

/*

 */
package com.sap.is.isr.srs.tools.constants;

/**
 * @author D037195
 *
 * To change the template for this generated type comment go to
 * Window>Preferences>Java>Code Generation>Code and Comments
 */
public interface INavCodeConstants {

//	navigation codes / commands for outbound plugs 
	static final public String NAV_CODE_COPY 		= "copy";
	static final public String NAV_CODE_CANCEL 		= "cancel";
	static final public String NAV_CODE_EXIT		= "exit";
	static final public String NAV_CODE_OVERVIEW 	= "overview";
	static final public String NAV_CODE_SAVE		= "save";
	static final public String NAV_CODE_SUSPEND		= "suspend";
	
	static final public String NAV_CODE_ADD_ITEM	= "addItem";
	static final public String NAV_CODE_CHANGE_ITEM	= "changeItem";
	static final public String NAV_CODE_DELETE_ITEM	= "deleteItem";
		
	static final public String NAV_CODE_HEADER_DETAIL	= "headerDetail";
	
	static final public String NAV_CODE_SEARCH_MATERIAL = "searchMaterial";

	static final public String NAV_CODE_ITEM_DETAIL	= "itemDetail";
	static final public String NAV_CODE_ITEM_TEXT	= "itemText";
	
	// navigation codes for inbound plug of Article Interface View
	static final public String NAV_AM_SCAN = "scanView";
	static final public String NAV_AM_ADV  = "advancedSearchView";
	static final public String NAV_AM_ADV_KEEP_PARAM  = "advancedSearchViewKeepParam"; //2007-05-25
	static final public String NAV_AM_LIST = "articleList";

}

Even if we get the text itemDetail from the below; how it is actually navigating to that view.

static final public String NAV_CODE_ITEM_DETAIL	= "itemDetail";

Thanks & Regards

Hi Kaushik,

From what I can read of the code provided, the actual navigation is don in this line of code:

wdThis.wdFirePlugItemsOverviewDone(INavCodeConstants.NAV_CODE_COPY);

If you open the appropriate Windows component in NWDS, you'll see a graphical representation of the navigation paths. Your view GrItemsOverviewView will have an outbound plug (red) with a navigation link to the inbound plug (blue) of view GrItemDetailView.

Apparently, the outbound plug 'ItemsOverviewDone' accepts a parameter of type String (which comes from your Constants file)

In the code of view GrItemDetailView, check method onPlug<WhateverInboundPlugIsUsedByAforementionedOutboundPlug>

I assume it will contain conditions based on the static variables in your Constants file, handling the requests

Hope this explains!
