    <screen name="main-decorator">
        <section>
            <actions>
                <property-map resource="CommonUiLabels" map-name="uiLabelMap" global="true"/>
                <property-map resource="PracticeUiLabels" map-name="uiLabelMap" global="true"/>
                <set field="layoutSettings.companyName" from-field="uiLabelMap.PracticeCompanyName" global="true"/>
                <set field="layoutSettings.label1" from-field="uiLabelMap.PracticeApplication" global="true"/>
                <set field="layoutSettings.label1" from-field="uiLabelMap.PracticeApplication" 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"/>
