Subsection Manager causes an error with Elastic Search extension...

[bzerangue]

When I set 'build-entry-xml' => 'yes' in the SubsectionManager preferences, it generates the following error...

Fatal error: Class 'extension_subsectionmanager' not found in /Repositories/pcpc/extensions/subsectionmanager/fields/field.subsectionmanager.php on line 696

Very similar to this error.

I am running Symphony 2.3.3 and Subsection Manager 3.5.1

Do you know what could be causing this problem?

This seems to fix the issue...

Add require_once(EXTENSIONS . '/subsectionmanager/extension.driver.php'); at the top of the class.subsectionmanager.php. Do you know if this would cause issues elsewhere?
