I know that the data is still there. If I create a new ZSQL method I can search and display the data. (There is hence a work around by redoing everything.) But how do I fix the problem? Being able to delete the methods after I have implemented the methods again and hence the workaround would be a possible solution. Ideally there is a way to get Zope to view the methods correctly.
