How to get rows ordered by a localized field.
My service.xml file defines an entity called ‘InstitutionType’, which defines a localized string field named ‘name’, as it can be seen below, and I wonder how I should proceed to get the entity’s instances ordered by this localized field.
On one hand, the methods automatically generated by Service Builder only have a “locale” parameter in the persistence object, but not in the InstitutionTypeLocalServiceUtil class.
On the other hand, the returned list of the method "InstitutionTypeLocalServiceUtil.getInstitutionTypes(start, end)" is ordered by ”Name” field, but according to Name field’s xml-content, and without taking into account the localized values of the xml content.
Does anyone know if Liferay provides some kind of utility that deals with this issue? Or, should I have to implement my own “wrapped” methods to get the result list and then create a second list ordered by the localized values of the initial list?
Thanks,
Santiago

<entity name="InstitutionType" local-service="true" remote-service="false">
<column name="institutionTypeId" type="long" primary="true" convert-null="false"></column>
<column name="name" type="String" localized="true"></column>
<order by="asc">
<order-column name="name"></order-column>
</order>
</entity>

That behavior is a limitation of current localization implementation using xmls.
Future Liferay 7.1 will add a new localization implementation using an additional table. (xml will be also available)
In Liferay 6.2 and 7.0 you have to apply a workaround:
- For example Liferay code usually index the localized data in elasticsearch/solr/lucene (with an indexer) and it queries that index instead of database.
- If you don't want to use the index, you have to sort data after quering the database, but be careful with throughout!
