When I was looking in a jsff-file I saw that the pageTemplate component showed an error.
the error: JSP page template not found
This will not cause any problems to run you’re application, but it is correct to solve problems.
1. Then you have to add the url to the custom template in the
pagetemplate-metadata.xml
2. go to ViewController > Application Sources > META-INF > pagetemplate-metadata.xml
3. Add a line which define the template of the page:
<pagetemplate-jsp-ui-def>/common/pageTemplates/ExamplePageTemplate.jspx</pagetemplate-jsp-ui-def>
