Hello Gurus, After along dicussion I can finally start creating a custom model. I created a simple ant file to run model validation tool. Validation of Alfresco provided models completed with a message that the TestModel application found an invalid model. For no apparent reason it cannot find a bootstrap model called: dictionaryModel.xml. I chcecked the my classpath and the dictionaryModel.xml file is present on the classpath. Another question is if thsi behavior can be treated as normal. When should I treat output of TestModel application as correctly stating that my model is invalid? Cheers, Pawel.
