is there a way to deep copy data into an instance *preserving* what is already there?

[Luis Tavera]

Hi

I am trying to implement an interface with two selects and a two buttons to move the selected items from the first to the second or from the second to the first, but when I do a deep copy of the items (as in the deep-copy.xml example) the destination is overwritten with the source data. Is there a way to insert without overwriting?

thanks

Hi Luis,

This might not be as easy as it seems to implement this with XForms.

First, I would use select/itemset/copy to always have a copy of each set of selected items somewhere in a work instance.

Then, each trigger should copy the corresponding selected items using insert at the end of the targeted select. Please have a look at https://www.w3.org/community/xformsusers/wiki/XForms_2.0#The_insert_Element for more details.

Finally, deleting the inserted copy should be enough to refresh the initial select.

This has not yet been tested with XSLTForms...

Thank you for your feedback!
