Transform any configuration plain array into a dynamic and configurable object structure, and pull apart configuration handling from the main logic of your script. Use provided services to add more functionality to your objects: cache, parents, persistence and much more.
I came across your extension for TYPO3 CMS it is very interesting and useful.
I would like to use him with "ext:form".
But I do not know how to use your 'ext:configuration_object' with 'ext:form'?
I need your help.
