Hi,

I am developing a custom module. Everytime I change anything and restar the server I get this error:

 return self.app(environ, start_response)
  File "/usr/lib/python2.7/dist-packages/openerp/http.py", line 1426, in dispatch
    ir_http = request.registry['ir.http']
  File "/usr/lib/python2.7/dist-packages/openerp/http.py", line 346, in registry
    return openerp.modules.registry.RegistryManager.get(self.db) if self.db else None
  File "/usr/lib/python2.7/dist-packages/openerp/modules/registry.py", line 339, in get
    update_module)
  File "/usr/lib/python2.7/dist-packages/openerp/modules/registry.py", line 370, in new
    openerp.modules.load_modules(registry._db, force_demo, status, update_module)
  File "/usr/lib/python2.7/dist-packages/openerp/modules/loading.py", line 351, in load_modules
    force, status, report, loaded_modules, update_module)
  File "/usr/lib/python2.7/dist-packages/openerp/modules/loading.py", line 255, in load_marked_modules
    loaded, processed = load_module_graph(cr, graph, progressdict, report=report, skip_modules=loaded_modules, perform_checks=perform_checks)
  File "/usr/lib/python2.7/dist-packages/openerp/modules/loading.py", line 152, in load_module_graph
    models = registry.load(cr, package)
  File "/usr/lib/python2.7/dist-packages/openerp/modules/registry.py", line 163, in load
    model = cls._build_model(self, cr)
  File "/usr/lib/python2.7/dist-packages/openerp/models.py", line 595, in _build_model
    original_module = pool[name]._original_module if name in parents else cls._module
  File "/usr/lib/python2.7/dist-packages/openerp/modules/registry.py", line 102, in __getitem__
    return self.models[model_name]
KeyError: 'stock.picking'

I have to rename the module folder under /openerp/addons/custom, restart the server, uninstall the module and then I can reinstall it again.

Why is this happening? Is there any information in the error that could be used to debug this?
