Liferay: field missing after Wizard Setup?

A workmate has just set up a local liferay dxp 7.1 instance (hypersonic) and then tried to import a LAR file from another 7.1 instance.

For me it worked (postgres), he's getting an error regarding a missing field:

No such field com.liferay.portal.model.impl.GroupImpl._originalName
---- Debugging information ----
message : No such field
com.liferay.portal.model.impl.GroupImpl._originalName
field : _originalName
class : com.liferay.portal.model.impl.GroupImpl
required-type : com.liferay.portal.model.impl.GroupImpl
converter-type : com.thoughtworks.xstream.converters.reflection.ReflectionConverter
path : /StagedGroup/_group/_originalName
line number : 32 class[1] : com.liferay.site.internal.model.adapter.StagedGroupImpl
version : 1.4.10

Since tickets are always time consuming I'd like to ask here first wether anyone has any hint regarding the underlying problem...

Solution

It's hard to say based on the limited information you've provided. Here are few things to double-check:

the LAR file didn't get corrupted while transferred over the wire
both instances of Liferay DXP are exactly the same (including Service Packs)
both instances have the same hot-fixes installed
both instances have the same staging configuration for the imported site
both instances have the same plug-ins/hooks that customize the import/export behaviour

If those are in place and you still have the issue, open a support ticket.

I don't think this is a DB related issue but to rule that out you can switch your instance to hypersonic and try the import.
