6. Save and return to Liferay

 

Expected results:

The google doc can be saved, and the title "Untitled" has existed in the portal as another entry's filename, so the new google doc entry in the portal should be renamed to "Untitled (1)" and the filename rename to "Untitled (1).docx"

Actual results:

The portal is crashed after clicking the "save and return to liferay"
