Custom Aspects not working after rule added

[umair_qureshi]

I followed chapter 7 of the Alfresco book for creating custom aspects. Everything worked out fine, I changed the code as per the instructions in the web-client-config-custom.xml file and the customeModel.xml file. I was able to get as far as adding the rule with the aspect of customer details, however, when I go to add a file I get the following error:

"  Please correct the errors below then click OK.
A system error happened during the operation: Transaction didn't commit: The aspect is invalid: {custom.model}CustomerDetails "

Please let me know if I need to provide more info. I would appreciate any help.

thanks.

i solved it
in customModel.xml file namespace must be:

<namespaces>
      <namespace uri="custom.CustomerDetails.model" prefix="custom"/>
   </namespaces>‍‍‍
