[one-users] OCCI syntax - [Wrong type! error]

[Strutz, Marco]

Hi.

Thanks for helping.
I have updated to the latest git-version but there is still the same
"Wrong Type!" message.

Perhaps it is really a problem about the occi syntax? Is there a way to
validate it? Is it possible to manually add some debug-output to the
ruby code: which file is responsible for parsing the xml description?


Thanks
Marco

Hi,

The reason of that error is a typo in the common.erb file. It was fixed
in the last maintenance release. [1]

In the python code, you have to use the VM template syntax [2], because
you are interacting with the core using the xmlrpc api.

Hope this helps.
