I get this all the time now when I am typing something in the ControlSource property in PEMEditor. I know it happens for the ControlSource of a grid column, because it just did. If I type THIS. it will throw this error as soon as I type the period. In the case just now, for the grid column, I typed the name of a cursor that will exist at runtime but does not exist at designtime and as soon as I type the period, I get the error. I’ve used THIS.<someformproperty> and <somecursorname>.<somefieldname> bunches and bunches in the past without these errors. I have the latest version of Thor and PEMEditor, as indicated by the check for updates feature (not sure how that’s working with GitHub at the moment). I suppose I can delve into the code, but I’d like for my changes (if I do that) to not get overwritten the next time there is an update.
