I’ve encountered what appears to be a bug that occurs when dragging projects from one document to another. I am running TaskPaper 3.3.1 from the Mac App Store on OS X 10.11.5.
- Create 2 documents (A and B) each containing a couple of projects and child items
- Drag a project from document A to document B, from sidebar to sidebar
- Drag the project from document B back into document A
The final versions of the documents are unchanged, as the project was moved and then put back into document A. The project was added to document B and then removed from document B.
The project and children from document A are moved (not copied) to document B on the first drag and drop. When dragged from B to A, the project simply disappears from both documents and cannot be recovered via undo.
Overall, I have found that dragging objects between documents has very uneven - and untrustworthy results. Variations on this recipe will yield different results, all of which may result in a loss of data during drag and drop operations.
