I copied the below xml into a new window:
<DisbursementSources type="collection" importStrategy="updateCreateNewIfNotFound" size="1" name="disbursementSources"></DisbursementSources>
This is well formed xml. If I select Pretty Print (xml only – with line breaks) I get this:
<DisbursementSources type="collection" importStrategy="updateCreateNewIfNotFound" size="1" name="disbursementSources"/>
The plugin took it upon itself to remove the empty end tag (</DisbursementSources>) and update the tag by adding a slash. Both versions are correct. However, the plugin decided the empty tag should no longer exist. Entirely misleading in my opinion!
