I would like to add one login page and after the user has logged in a Master-Detail application should be loaded. I have taken this template for the Master Detail application: https://github.com/SAP/openui5-masterdetail-app. How can I achive that?
With App.xml as root view it's loading the login page but it's also telling the App that to search ID "layout", wich is not anymore in App.xml but in Main.xml
"controlId": "layout",
"controlAggregation": "beginColumnPages",
I have exchanged the pages of the original template
App.xml (is now the login page):
<mvc:View controllerName="sap.ui.demo.masterdetail.controller.App"
xmlns:html="http://www.w3.org/1999/xhtml" xmlns:smartFilterBar="sap.ui.comp.smartfilterbar"
xmlns:smartTable="sap.ui.comp.smarttable" xmlns:mvc="sap.ui.core.mvc"
xmlns="sap.m">
<App id="app">
<pages>
<Page title="{i18n>title}">
<content>
<VBox fitContainer="true" justifyContent="Center" alignItems="Center"
alignContent="Center">
<items>
<Label id="lblLoginUser" text="User" labelFor="inputLoginUser"/>
<Input id="inputLoginUser" placeholder="User ID" value="{loginBody>/email}"/>
<Label id="lblLoginPassword" text="Password" labelFor="inputLoginPassword"/>
<Input id="inputLoginPassword" placeholder="Password" type="Password" value = "{loginBody>/password}"/>
<Button width="12rem" text="Login" type="Emphasized"
press="onLoginTap"></Button>
<Link id="linkRegister" text="{i18n>register}"
href="{loginUI>/linkRegister}"></Link>
<Link id="linkResetPassword" text="{i18n>resetPassword}" visible="{loginUI>/showLinkResetPassword}"
href="{loginUI>/linkResetPassword}"></Link>
</items>
</VBox>
</content>
</Page>
</pages>
</App>
</mvc:View>
Main.xml (is the original App.xml)
<mvc:View
controllerName="sap.ui.demo.masterdetail.controller.Main"
displayBlock="true"
height="100%"
xmlns="sap.m"
xmlns:f="sap.f"
xmlns:mvc="sap.ui.core.mvc">
<App
id="main"
busy="{appView>/busy}"
busyIndicatorDelay="{appView>/delay}">
<f:FlexibleColumnLayout
id="layout"
layout="{appView>/layout}"
backgroundDesign="Translucent">
</f:FlexibleColumnLayout>
</App>
</mvc:View>
