    Problems setting Datasource in Component XML

    I am trying to define my own ListGrid using a custom constructor like this (similar to the customComponent example in the EEShowcase):

    CustomListGrid.ui.xml
    Code:
    <ListGrid xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
    constructor="com.aCompany.client.CustomListGrid"
    ID="CustomListGrid" autoDraw="false" dataSource="SomeBean" autoFetchData="true"
    width="600" height="400">
</ListGrid>
    SomeBean.ds.xml
    Code:
    <DataSource 
	beanClassName="com.aCompany.SomeBean"
	ID="SomeBean"
	serverType="hibernate"
	autoDeriveSchema="false"
    dropExtraFields="true"
>
	<fields>
		<field primaryKey="true" name="id" type="sequence"></field>
		<field name="anotherBeanId" type="integer"></field>
		<field name="aProperty" type="text"></field>
		<field name="anotherBean" title="AnotherBean" canEdit="false" foreignKey="AnotherBean.id" multiple="true">
            <displayField>anotherProperty</displayField>
            <filterEditorType>SelectItem</filterEditorType>
            <optionDataSource>AnotherBean</optionDataSource>
            <valueField>id</valueField>
        </field>
	</fields>
</DataSource>
    This works, as long as dataSource="SomeBean" autoFetchData="true" are ommited in above customComponent definition for the CustomListGrid and the respective properties are set programmatically like this
    Code:
    RPCManager.loadScreen("CustomListGrid", new LoadScreenCallback() {			
	@Override
	public void execute() {
		final DynamicForm dynamicForm = (DynamicForm) Canvas.getById("ViewsForm");
		final ListGrid filmGrid = (ListGrid)Canvas.getById("CustomListGrid");
		
		DataSource filmDS = DataSource.get("SomeBean");
		filmGrid.setDataSource(filmDS);
    Otherwise (if set directly in the CustomListGrid's component XML), the following exception is raised:
    Code:

    What could be the problem here?
