Olivier Heintz commented on OFBIZ-4949:
---------------------------------------
Paul, setOtherFieldsToNull est clearly better, thank's to propose it. I'll
correct the patch
Scott,
The goal is to avoid to give all field, to have xml data file with only field
with value.
ex: in PortalPortlet, if portletTypeId is populated, screeLocation is not
mandatory, because a default value exist (
${component}:widget/${subcomponent}Screens.xml ) so if a enhancement move the
screen to the default place, screenLocation should be change to null. It's the
same thing for screenName, menuName, menuLocation, scriptName, formName,
formLocation, ..... If the setOtherFieldsToNull not exist, it would be
necessary to give all field with a default value to be sure.
Clearly, PortalPortlet is the only use case where this new attribute will be
very usefull.
> add a new attribute for for entity-engine-xml tag, put-other-field-to-null=
> true, if it exist at the beginning data file, all update will put to null all
> field not detail in this file

> This enhancement is useful when a entity is load by reader (ex: seed) and
> sometime, it could be modify in data file. If a field is change from a value
> to null, currently this modification will not be done in the next load.
> For portletWidget, entity PortalPortal have a lot of field with potential
> default value, so sometime, first release use some field and when it's
> reviewed and corrected, some field are changed to null to use the default
> value (to follow best practice).
> This enhancement will be very useful for portletData file.
