Problem with validating a hutn file [message #1064530]

I am getting a "Cannot build model because HUTN cannot be parsed", when I have manually extended a hutn file, I've generated from a .model. Sometimes the hutn editor shows red x'es, but with no explanation, sometimes it does not. I cannot see why my hand-extended hutn file is invalid.

Attached are:
the ecore metamodel (watches.ecore)
the emfatic equivalent (autogenerated from the .ecore)
the manually (exeed) created .model (watches3.model, valid against the metamodel)
the autogenerated hutn file (watches3.hutn)
the manually extended .htn file that demonstrates the error (watches31.hutn)

Any advice appreciated thanks.

Julian.

Hi Julian,

As reported in the Problems view, this is caused by a duplicate object identifier (watchEntry2). Changing line 22 from:

}, watchEntry "watchEntry2" {

to:

}, watchEntry "watchEntry3" {

should make the error disappear.

Regards,
Dimitris

Dimitris

thanks. I've explored more the Problems view, so I better understand how to make use of the information in it.

Thanks, JJ.
