CoreException when using property tester to hide action in popup menu [message #327415]

In my plugin.xml, i used objectContribution/enablement/test to make an
action of a popup menu visible if the selection is a Project and contains
certain file.

Created a property tester that checks if it contains the file.

plugin.xml

<extension point="org...popupMenus">
<objectContribution
adaptable="true"
objectClass="org.eclipse.core.resources.IProject"

<enablement>
<test property="x.y.z.hasFile" />
</enablement>

<action...

</extension>

<extension point="org...propertyTesters" >
<propertyTester id="x.y.z.MyTester"
type="org.eclipse.core.resources.IProject"
namespace="x.y.z"
properties="hasFile"
class="x.y.z.MyTester"
</propertyTester>
</extension>

MyTester.java

public boolean test(...) {
// do something and return boolean
}

However, I got CoreException "No property tester contributes a property
hasFile to type class org.eclipse.core.internal.resources.Project"
What's wrong with what I did?

My guess is in my plugin.xml, I defined IProject type. But as you can see
in the exception "...No property tester... to type class org...Project"

I've been searching a lot of related threads here but none seems to be the
same as what I have encountered..

Any help will be appreciated, thanks.

Your XML certainly looks correct. Are there any errors/warnings
associated with the type="..." line in your plugin.xml from the PDE
builder? Does your plugin depend on org.eclipse.core.expressions
(probably) and org.eclipse.core.resources?

When you run, are there any other exceptions in your log?

Hi Paul,

Regarding your questions,

1. Are there any warnings/errors associated with the type="..."
- Nope,

2. Yes it depends on core.expressions and core.resources

3. When I right-clicked a project in the Package Explorer, the exception
occurs and is displayed in the Error log. No other exception besides this
happens performing the action.

org.eclipse.core.runtime.CoreException: No property tester contributes a
property hasPOM to type class org.eclipse.core.internal.resources.Project
at
org.eclipse.core.internal.expressions.TypeExtensionManager.g etProperty(TypeExtensionManager.java:109)
at
org.eclipse.core.internal.expressions.TestExpression.evaluat e(TestExpression.java:95)
at ....

Thanks for taking a look at this problem

it says hasPOM ... is that just different from your example (hasFile)?
