LayoutData causes ResourceException

Hello everyone,

I try to display some data via a Grid Layout and the use of LayoutData causes following exception:

Uncaught Error: failed to load 'sap/m/layoutData.js' from resources/sap/m/layoutData.js: 404 - Resource could not be found!

My sap-bootstrap looks like this:

<script  id="sap-ui-bootstrap"  src="resources/sap-ui-core.js"  data-sap-ui-theme="sap_bluecrystal"  data-sap-ui-libs="sap.m"  data-sap-ui-xx-bindingSyntax="complex"  data-sap-ui-resourceroots='{  "com.parcon.logixnet.tourman": "./"  }' ></script>

My view looks inpired by SAPUI5 Explored looks like this (problem line 15-17):

<core:View  controllerName="com.parcon.logixnet.tourman.controller.SubDetail"  xmlns:l="sap.ui.layout"  xmlns="sap.m"  xmlns:core="sap.ui.core" >  <Page  title="{empfaenger}"  showNavButton="true"  navButtonPress="handleNavButtonPress" >  <l:Grid  class="gridMarginTop"    defaultSpan="L6 M6 S6">    <l:content>    <Label text="adresse" design="Bold"/>         <layoutData>           <l:GridData span="L12 M12 S12" />         </layoutData>           <Text text="ort"/>         <Text text="{adresse/0/ort}" />    </l:content>      </l:Grid>     <Panel>    <headerToolbar>       <Toolbar height="3rem">         <Text text="{i18n>Adresse}"/>       </Toolbar>     </headerToolbar>     <content>       <Text text="sampleText"/>     </content>    </Panel>  </Page></core:View>

My sap.ui.version is 1.22.7 and I can't find the problem.

Any help is appreciated, Thanks,

Silvio.
