What is in the manifest:

{    "name": "Test module",

    "summary": "This is a test",  

  "depends": ["base"],  

  "data": [             'security/ir.model.access.csv',                             'views/test_module_views.xml'             ],  

  "installable": True, 

   "application": True,  

  "sequence": 1}

The security file:

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink

ws_test_module.access_test_module_model,access_test_module_model,ws_test_module.model_test_module_model,base.group_user,1,0,0,0

no errors when updating or installing and according to the settings it does have the read acces and it does have the menu...

but still it wont show up on the dashboard if it is installed.
