Hello Everyone, I am new here and want to thank everyone that has contributed to this project. I apologize in advance if the formatting of this becomes poor.
I am experiencing issues with Part-2 of the "OFBiz Beginner's Development Guide Using Practice Application". Part-1 works after i add: <handler name="screen" type="view" class="org.ofbiz.widget.screen.ScreenWidgetViewHandler"/> to my controller.xml file. I have made many, many attempts at this, hacking little things here and there and always get errors when running the application. These have varied depending on what I have changed, but the latest one is "java.lang.NullPointerException". I ended up unzipping the practice.zip attachment and using sections of the files from it. I have listed the steps below and commented where necessary: -----------------Step 1: My CommonScreens.xml file is as follows:---------------------------- <?xml version="1.0" encoding="UTF-8"?> <screens xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:noNamespaceSchemaLocation="http://ofbiz.apache.org/dtds/widget-screen.xsd";> <screen name="main-decorator"> <!-- The main-decorator screen 'wraps' or 'decorates' all of the screens in the practice component. It is also decorated - by the GlobalDecorator screen. --> <section> <actions> <!-- base/top/most specific map first, then more common map added for shared labels. Setting things up this way enables a component to redefine the more common UI labels. --> <property-map resource="CommonUiLabels" map-name="uiLabelMap" global="true"/> <property-map resource="PracticeUiLabels" map-name="uiLabelMap" global="true"/> <!-- The layoutSettings field is a Map that is used to pass variables and layout information to the GlobalDecorator and any templates that it uses. --> <set field="layoutSettings.companyName" from-field="uiLabelMap.PracticeCompanyName" global="true"/> <set field="activeApp" value="practice" global="true"/> <set field="applicationMenuName" value="PracticeAppBar" global="true"/> <set field="applicationMenuLocation" value="component://practice/widget/PracticeMenus.xml" global="true"/> </actions> <widgets> <include-screen name="GlobalDecorator" location="component://common/widget/CommonScreens.xml"/> </widgets> </section> </screen> <screen name="CommonPracticeDecorator"> <section> <widgets> <decorator-screen name="main-decorator"> <decorator-section name="body"> <decorator-section-include name="body"/> </decorator-section> </decorator-screen> </widgets> </section> </screen> </screens> -----------------------Step 2---------------------------------- I copied the contents of PracticeMenus.xml file from the practice.zip -----------------------Step 3------------------- Person.groovy created ------------------------Step 4---------------- Person.ftl created ------------------------Step 5-------------------- Here is my PracticeScreens.xml file: <?xml version="1.0" encoding="UTF-8"?> <screens xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

I am sure I am making a trivial mistake, but any help with this would be appreciated. Many Thanks!!
