Debugging Eclipse Core Expressions

I am building an Eclipse E4 RCP Application. I have a menu item that uses a core expression. Is there any way to debug this core expression?

I haven't worked with E4 yet but in 3.x you can debug the expressions. Expressions are derived from class org.eclipse.core.expressions.Expression.

Their class names match the expression, e.g. org.eclipse.core.internal.expression.WithExpression implements the with expression.

Assuming you know the expression type you want to debug, just set a breakpoint in the evaluate method of the class.

Be aware that expressions are widely used, so setting a breakpoint condition will save you a lot of breakpoint hits.
