I'm just new to mobile together and I'm following the tutorials. I'm at part three where an image will be rotated and changed in the detail record.
The tutorial video uses elements for image-source and edit-book-id. When I use the clear button to remove the image and then use camera or gallery to add a new this does not work.
With the installation there is the books.mtd app but this app uses attrbutes instead of eleents, over here using the clear button and then attaching an image works.
But if I change this example and add the delete-node as in the tutorial I get errors.
What should I use the tutorial or the installed example and what with th errors.
The error I get is when appending the image after the delete-node

• 'Append Node' has an invalid XPath 'attribute Image { mt-transform-image( $PERSISTENT/Root/@image-source, 500, 0, 50 ) }'
  
• Wrong occurrence to match required sequence type
  
• XPTY0004: The parameter value ('0' item(s)) at position '1' of the 'mt-transform-image' function has the wrong occurrence to match the sequence type xs:base64Binary ('exactly one')
  
• Cannot Update Node '$PERSISTENT/Root/@image-source' (no 'Target Node' found)

Hello there.

I made a word document with print screens and what happens where.
I also include the tutorial app I built ('BooksBuild.mtd') and the sample app 'Books.mtd'.
