In the following example I don't know how to write the path to a specific data. e.g. the id of the Property with the name prop1 of the Entity with the name Entity1.

<Composite xmlns="http://www.eclipse.org/xwt/presentation"
	xmlns:x="http://www.eclipse.org/xwt" xmlns:j="clr-namespace:testxwt"
	xmlns:k="clr-namespace:java.lang" DataContext="{StaticResource MyData}">
	<Composite.layout>
		<GridLayout numColumns="2" />
	</Composite.layout>
	<Composite.Resources>
		<j:Data x:Key="MyData">
			<j:Data.members>
				<j:Entity Name="Entity1" Id="1">
					<j:Entity.properties>
						<j:Property Name="prop1" Id="1" Value="32" Type="String" />
						<j:Property Name="prop2" Id="2" Value="27" Type="String" />
					</j:Entity.properties>
				</j:Entity>
				<j:Entity Name="Entity2" Id="2">
					<j:Entity.properties>
						<j:Property Name="prop1" Id="1" Value="32" Type="String" />
						<j:Property Name="prop1" Id="1" Value="32" Type="String" />
					</j:Entity.properties>
				</j:Entity>
			</j:Data.members>
		</j:Data>
	</Composite.Resources>
	<TableViewer Name="DataViewer" input="{Binding Path=members}">
		<TableViewer.columns>
			<TableViewerColumn width="150" text="Name"
				bindingPath="name" />
			<TableViewerColumn width="150" text="Id"
				bindingPath="id" />
		</TableViewer.columns>
		<TableViewer.table HeaderVisible="true" />

		<TableViewer.control.layoutData>
			<GridData horizontalAlignment="FILL" horizontalSpan="2"
				grabExcessHorizontalSpace="true" />
		</TableViewer.control.layoutData>
	</TableViewer>
	<Label
		text="{Binding ElementName=DataViewer,path=singleSelection.(j:Entity.name)}">
		<Label.layoutData>
			<GridData horizontalAlignment="FILL"
				grabExcessHorizontalSpace="true" />
		</Label.layoutData>
	</Label>
	<TableViewer Name="CompanyViewer"
		input="{Binding ElementName=DataViewer,Path=singleSelection.(j:Entity.properties)}">
		<TableViewer.columns>
			<TableViewerColumn width="150" text="Name"
				bindingPath="name" />
			<TableViewerColumn width="150" text="Id"
				bindingPath="id" />
			<TableViewerColumn width="150" text="Type"
				bindingPath="type" />
			<TableViewerColumn width="150" text="Value"
				bindingPath="value" />
		</TableViewer.columns>
		<TableViewer.table HeaderVisible="true" />

		<TableViewer.control.layoutData>
			<GridData horizontalAlignment="FILL" verticalAlignment="FILL"
				heightHint="200" grabExcessHorizontalSpace="true"
				grabExcessVerticalSpace="true" />
		</TableViewer.control.layoutData>
	</TableViewer>

	<Text  x:style="SWT.NONE"

                text="{Binding Path= the id of the prop1 of Entity1}"
        
         ></Text>

	</Composite>


Thanks for help

You should name this entity in the resources (for example Entity1) and then
<Text x:style="SWT.NONE"
text="{Binding Source={staticresource Entity1} Path=prop1}"
></Text>

Best regards
