Re: [udig-devel] New Attribute added in internal.ecore

[Trupti Pol <ktrup7@xxxxxxxxx>]

Hi Andrea,

if reload models from java interfaces then there is no modifications in the
model and ecore files.
But if i try and regenerate model code from these models then i get the
compiler errors.

Currently what i have done is 
  1) added one extra attribute in internal.ecore
  2) generated the model code

It gives me compiler errors. Following problems are prominent.
   1) .java file method's signatures are changing.
   2) every .java file has copyright string declaration missing.
   3) Instead of retrieving information from ProjectPackage.eINSTANCE.** now
the statement is modified to ProjectPackage.Literals.**
   4) eGet() and eSet() methods instead of using EStructuralFeature now uses
int featureID

Please tell me about how to get model and code in sync with each other? Also
give me some pointers about handling above issues.
