Decorator class stays null [message #294599]

Hi all,

I'm trying to write my own decorator and have the following problem:
MoreUnitPlugin.getDefault().getWorkbench().getDecoratorManag er() has a
reference to my LightWeightDecoratorDefinition but the
decorator-instance-variable is always null.

Here is the code snippet from my plugin.xml:

<extension point="org.eclipse.ui.decorators">
<decorator
id="moreunit.testdecorator"
label="Decoratorlabel"
state="true"
class="moreUnit.decorator.UnitDecorator"
adaptable="true"
lightweight="true">
<enablement>
<objectClass name="org.eclipse.core.resources.IResource"/>
</enablement>
<description>
Description.
</description>
</decorator>
</extension>

The UnitDecorator-class implements the
ILightweightLabelDecorator-interface and extends LabelProvider.

Any hints what I'm doing wrong?
Thanks for help.

Vera

Ok I solved it.
In my workspace I had installed the DemoDecorator-example from the
eclipse-homepage. After deactivating the demo-decoration of this plugin
my own decorator worked.
