Module Interfaces - how to call a module from another module
This is just an example from the existing WCEM Standard Code.
Main module has headerView.xhtml which calls LoginRegisterAnchor using tag <wec:moduleInterface>
<wcf:moduleInterface id= "iSIn" name ="com.sap.user.LoginRegisterAnchorView" rendered ="#{cc.vch.userActive}" viewComponent ="mainpageLoginRegisterAnchorView"/>
Also, in the headerView.xhtml, we can see below one calling loginInfo.xhtml
<wcf:moduleInterface id= "iLI" name= "com.sap.user.LoginInfoView" viewComponent ="mainpageLoginInfoView"/>
For both loginInfo.xhtml and loginRegisterAnchor.xhtml - if you see ui-repository.xml, both point to VCH:
<ViewComponent name="loginRegisterAnchor" componentHandlerClassName="com.sap.wec.app.common.module.user.ui.user.mainpage.vc.impl.MainPageLoginRegisterAnchorVCHandler" />
<ViewComponent name="loginInfo"
componentHandlerClassName="com.sap.wec.app.common.module.user.ui.user.mainpage.vc.impl.MainPageLoginRegisterAnchorVCHandler" />

Answer from forum:
In your case (headerView.xhtml):
- Main module declares that it wants to use a module interface 'com.sap.user.LoginInfoView' in its metadata.xml
In the main module, sap -> md, you can see metadata.xml has
<interfaceDependency dependencyType="soft"
interfaceName="com.sap.user.LoginInfoView"namespace="sap"/>
<interfaceDependency dependencyType="soft"
interfaceName="com.sap.user.LoginRegisterAnchorView" namespace="sap" />
- User module declares that it implements 'com.sap.user.LoginInfoView' in its interface-definition.xml, and that one view with name 'mainpageLoginInfoView' is exposed
<!-- View Interface for the log on link and status used in the header
-->
<module-interfacename="com.sap.user.LoginRegisterAnchorView">
<viewviewName="mainpageLoginRegisterAnchorView"/>
</module-interface>
<!-- View Interface for the user name display used in the header -->
<module-interfacename="com.sap.user.LoginInfoView">
<viewviewName="mainpageLoginInfoView"/>
</module-interface>
- User module provides the implementation details in its metadata.xml. It states
<uiInclude name="mainpageLoginInfoView"usedUiInclude="user/systemlinks/loginInfo_INC"
<!-- VIEW Interface implementations -->
<interfaceImplementationinterfaceName="com.sap.user.LoginInfoView">
<uiIncludename="mainpageLoginInfoView"usedUiInclude="user/systemlinks/loginInfo_INC"/>
</interfaceImplementation>
So you need to look for include user/systemlinks/loginInfo_INC!
- User Module - endter the UIInclude in the ui-repository.xml
<UIIncludename="user/systemlinks/loginInfo_INC"/>
