Error deploying Content Model

[padmalaya]

I am using the conventional method of deploying a new content model, uploading customModel.xml,custom-model-context.xml and web-client-config.xml in the extensions folder.

However , whenever I customize a new custom model, I get Invalid Aspect error, or else a memory leak.
I have one more query, how do I deploy a model without aspects? And if I do , how do I know that the given model is active and that the content being uploaded used the model defined for it.

Thanks in advance,

Padmalaya

Before deploying the model you should try to start using the TestModel class provided by Alfresco that allows you to test the model parser of Alfresco before injecting in the model in the repository:
http://wiki.alfresco.com/wiki/Data_Dictionary_Guide#Step_5:_Testing_the_Model_definition

You can create your own model using types without any aspects:

Hope this helps.
