Cancel button doesn't work after editing metadata when the +-button is used during editing

[gvandeboel]

First i click the edit-button of a result after a search. Next i click on the +-button to create by example an extra Point of interest. My page is updated and the Point of interest is added. After clicking the cancel-button, all my edits i have done are saved and that is not correct. When i don't have used the +-button during editing, my edits are correctly not saved. In the java-code i have seen that if you add a Point of interest or somewhat else by clicking the +-button, the metadata is always saved by the method updataMetadata. Is there a possibility to prevent the update or cancel the updated metadata after clicking the cancel-button ? There is also the same problem when creating new metadata and canceling immediatly the empty created metadata. Please some help.
