[news.eclipse.modeling.mdt.ocl] Re: New to EMF and OCL

[Richard Catlin <richard.m.catlin@xxxxxxxxx>]

Further thoughts on this question:

If I create a simple EClass called Architecture in Ecore with a property 
of "hardwareNotes", then when I generate the model, a 
setHardwareNotes(String name) method is generated.  When I use the 
Interactive OCL Console, I get the following error:

self.setHardwareNotes('hw1')

Cannot find operation (setHardwareNotes(String)) for the type (Architecture)

How can I go about setting this?

Thank you,
Richard
