Upgrade from ember 1.0.0beta16 to 1.0.0beta19.2 adapter issue

I have updgraded the application from 1.0.0beta16 to 1.0.0beta19.2, however 1.0.0beta19.2 is unable to execute the name space for training trainingCompliance : belongsTo(‘user.training.compliance’), or trainingRequired: Em.computed.readOnly(‘trainingCompliance.required’),

Adopter names actually exist and works fine with 1.0.0beta16

file names of the adopters are

app\adapters\training-compliance.js app\adapters\user-training-compliance.js

are there any known adapter resolution issues with beta19. Same issue like in beta 19 exists even with emberdata 1.13.15 too.
