Hello Wouter.

Thanks for your reply. I'm afraid some things have still changed.

Therefore I'd like to ask you following questions:

• In the tutorial at hand I'd like to know what I've to change in order to remove all generated useless temp* files as you can see in the screenshot.
• 
• Is it correct to run it as "Run as plugin" -> since "Run as Feature" isn't available anymore?
• I followed exactely your described instructions. I managed to generated my app with the wizard where I found my template in debug mode. But at runtime he doesn't recognize my
  new "App.view" file although it's physically there.

  Log-dbg.js:456 2020-03-20 08:27:27.698064 Failed to load component for container container. Reason: Error: resource test2/view/App.view.xml could not be loaded from resources/test2/view/App.view.xml. Check for 'file not found' or parse errors. Reason: -

  I also added it as root view in the manifest.file:

• 	"sap.ui5": {
  		"rootView": {
  			"viewName":"{{basicSAPUI5ApplicationProject.parameters.namespace.value}}.view.App",
  			"type":"XML"
  		},​

  and in the model.json of the build project:

  {
  	"neoapp": {
  		"welcomeFile": "/webapp/index.html",
  		"sendWelcomeFileRedirect": true
  	},
  	"basicSAPUI5ApplicationProject": {
  		"parameters": {
  			"ViewTypesCollection": {
  				"type": "String",
  				"binding": [{
  					"name": "None",
  					"value": "None"
  				}, {
  					"name": "XML",
  					"value": "XML"
  				}, {
  					"name": "JSON",
  					"value": "JSON"
  				}, {
  					"name": "JavaScript",
  					"value": "JS"
  				}, {
  					"name": "HTML",
  					"value": "HTML"
  				}],
  				"value": "@basicSAPUI5ApplicationProject.parameters.ViewTypesCollection.binding.1",
  				"wizard": {
  					"control": "ComboBox",
  					"required": true,
  					"title": "basicSAPUI5ApplicationProject_view_type_title",
  					"tooltip": "basicSAPUI5ApplicationProject_view_type_tooltip",
  					"sort": "false"
  				}
  			},
  			"namespace": {
  				"type": "string",
  				"value": "",
  				"appDescriptor": {
  					"id": "Namespace"
  				},
  				"wizard": {
  					"control": "TextField",
  					"required": true,
  					"title": "basicSAPUI5ApplicationProject_namespace_title",
  					"regExp": "(?!(sap|new(\\..*)*)$)^[a-zA-Z_][\\w-]*(\\.[a-zA-Z_][\\w-]*)*$",
  					"regExpErrMsg": "nameSpace_model_parameters_name_validationError"
  				}
  			},
  			"name": {
  				"type": "string",
  				"value": "App",
  				"wizard": {
  					"control": "TextField",
  					"required": false,
  					"title": "basicSAPUI5ApplicationProject_view_name_title",
  					"regExp": "^[a-zA-Z_]+[a-zA-Z0-9\\-_]*$",
  					"regExpErrMsg": "viewXML_model_parameters_name_validationError"
  				}
  			}
  		},
  		"forms": [{
  			"title": "",
  			"type": "templateCustomizationStep",
  			"groups": [{
  				"title": "emptyMobileProject_model_form_group_title",
  				"parameters": ["@basicSAPUI5ApplicationProject.parameters.ViewTypesCollection", "@basicSAPUI5ApplicationProject.parameters.name"]
  			}]
  		}, {
  			"type": "appDescriptorGenericStep",
  			"groups": [{
  				"parameters": ["@basicSAPUI5ApplicationProject.parameters.namespace"]
  			}]
  		}]
  	}
  }​

  If you want - I can send you the build project.

  My aim is to get it running once without the overhead of the unnecessary files and recognizing the new view.

Thank you.

Regards
