I have successfully loaded several XML batch files created manually of past issues from another system into an version 220.127.116.11. I just tried unsuccessfully importing a batch file exported directly from on version 18.104.22.168 into the 2.2 system. I am getting the following error message:
"Fatal error: Call to a member function getFilePath() on a non-object in /usr/local/apache2/htdocs/ojs/plugins/importexport/native/NativeImportExportPlugin.inc.php on line 138"
I found the following post here in the system for what appears to be the same problem at http://pkp.sfu.ca/support/forum/viewtopic.php?f=8&t=1224&p=3801&hilit=function+getFilePath#p3801
"I'm using the web-based import. The error I was getting was "Call to member function getFilePath() on a non-object in /ojs/plugins/importexport/native/NativeImportExportPlugin.inc.php on line 137" but after I adjusted the file size upload limit that error went away. I then got a db error on the temporary_files type column being null, but Bugzilla #2251 (dropping the column) fixed that. So it now all appears to have worked and imported nicely. Thanks for all your help."
Can you please advise whether my problem might be the same or not and, if so, point me in the right direction to correct the problem. Thanks in advance.
