Hi,

I want to use an class with static methods with first paramater java.util.Date in the domainmodel example. The user should not have to use that import in the .dmodel, but I want it to be always there. I found the ImplicitlyImportedFeatures and overwrote it. I have to extension methods in that class:

	public static boolean operator_lessThan(
			final Date a,
			final Date b )
	{
		...
	}
	public static final boolean isJuly(
			final Date date )
	{
		...
	}

In the .dmodel if have such an operation:

		op anyDate : Date {
			val d1 = new Date
			val d2 = new Date
			if (d1 < d2) {
				
			}
			if (d1.isJuly) {
				
			}
		}

The first if-condition maps correctly to "operator_lessThan" but the "isJuly" is not found: "The method or field isJuly is undefined for the type Date"

What am I missing?

Thanks in advance
Ingo

Hi i cannot reproduce that in 2.8.4
are you sure you get the classpath right. of both the project containing your ImplicitlyImportedFeatures and the project containing the test.dmodel file?

Hi, thanks for the classpath hint. It was a missing dependency which was a hidden by Eclipse due to our more complicated setup.
So this one is solved and is working as expected.
