Namespace prefix is not mapped to a namespace URI

ebogaard — Wed, 29 Aug 2012 09:11:19 GMT

Hi there,I've developed several custom aspects and workflows, but now I keep on running into the really annoying 'Namespace prefix is not mapped to a namespace URI', and I can't solve it myself. Maybe I'v looked at the code so much, that I can't see the error anymore.Because of the error, I can't st

Do you have any other custom content model file.
There could be a case where in other model also you are using same prefix example with different URI

Thanks for your answer.
This is the only custom model in this Alfresco-installation, so it shouldn't be the cause. To be sure, I did a thorough search and found nothing.
So that's not the problem.

But maybe there is a model dynamically loaded in the data dictionary. Is there some way to startup Alfresco by continuing, even when the namespace-error shows up?

also check that you do not have two copies of same model one under the file system
another in alfresco under Data Dictionary/Models

As it should be at any one of the location only.
If you want to load it dynamically you can place it under second location and no need of context file.
And just reload it from the admin-repo console

The funny thing is, that I can't start Alfresco anymore because of the problems in the first post. So there is no way to delete the model from the Data Dictionary. Or is there?

If you remove the model entry from you context file you will be able to start the alfresco

I'm afraid that isn't the case. After renaming the custom-context.xml, I still get the errors.
I searched the shared/classes/alfresco - folders, but there are no other custom models being loaded. And I never work outside this folder.

could you just removed the file temporary rather then rename?
And if you have renamed you need to change the extension from .xml to .sample

I renamed the extension, so the file isn't recognized.
Also, after a search, I found several other files where the namespace prefix is used. Amongst others the share-config-custom and a Solr-model, but after deleting/renaming those, the problem still persists.
So now I'm 100% sure that there is no file which refers to the namespace prefix mentioned in the logfile, but I still get the error.

The problem is just with namespace prefix called "example"
I do not think that this prefix "example" exist anywhere else.
You are missing something for sure.
Please check the namespace prefix related document for alfresco to get clarity on the funda.

Just one question (as I've read the Data dictionary- and Workflow-documentation several times): is it possible to add your own namespace?
Now I've used 'example' or 'abc' for example, as I always thought you should use your own to be sure the namespace is unique. But because of your remark, I'm not so sure anymore.

Re: Namespace prefix is not mapped to a namespace URI

Well you are right that we need to use the unique prefix and also a user define prefix like 'abc' of 'newpref' etc..
But the thing is you can use one prefix for one model only if you have more models you need to use other one.
And as you have mentioned you have found it in solr model as well that confuse me.

So, just make sure that you have used the prefix in one model only.
And if you removed the context file it will not load model any more so you should not get error as well.

so in case if we changed prefix or uri , we would be left with only last option to reinstall alfresco.
i have one confusion in which file we add forms of workflow in
tomcat\webapps\share\WEB-INF\classes\alfresco\share-workflow-form-config or
in tomcat\shared\classes\alfresco\web-extension\share-config-custom .
i m using share-workflow-form-config file and its working but where we use share-config-custom file.
