When a question is downloaded from Minibix, the metadata shown in the metadata dialog comes from Minibix, but the Description field is not included.
Although visible in the dialog, the metadata does not seem to be inserted in the model, so unless changes are made to a field it is not in the metadata for the edited question.
Hence, when saving to Minibix, the metadata is incomplete, and at this stage the taxonomy position cannot be set, so the user must go and edit the metadata again.
Description field now kept. I didn't have trouble with the metadata sticking
In 0.7.1, the metadata is not kept:
I see a full page of metadata on downloading from Minibix, including the Description,
I change the name and ticket number and click Apply and OK,
Re-entering Metadata immediately, it looks fine still at this point,
I go and edit stuff - the MathML in the question body and add the variable and its randomisation in the processing,
On going to upload back to Minibix, the upload dialog shows the metadata has lost several fields including Description, Taxonomy and Author,
Going back to edit the metadata, the fields are empty...
The metadata is cleared on return from the Processing editor (Validatr-type editor); editing the question body and adding a variable do not affect it.
