Upgrading from Liferay 6.1 to 6.2 Part 4

09 April 2016

During our upgrade from 6.1 to 6.2 we discovered two bugs with Documents and Media portlet. Specifically these bugs presented themselves after applying 6.2 EE Fix Pack 95 to 6.2 SP14. The first issue involved the JSPs and Javascript with the portlet. On line 79 of the main.js file they changed “instance.ns(‘dataRequest’);” to “instance.ns(‘entryDataRequest’);”. This change was not made in all of the JSP files. The second issue was a data layer issue that appears as a combination of upgrading and the fix pack. The error occurred when trying to edit and then save documents that existed prior to the upgrade. It did not affect documents created after the upgrade. The error is shown below.

How in the Heck do I give a presentation?

29 March 2016

Presentations seem so very difficult. Something that takes hours of preperation and rehearsal … or so I thought. We just had a conversation with Kristen Hunter that showed us a better way. She presented here in Louisville, KY for CodePaLOUsa. Many of us want to discuss and share what we are excited about with others. Figuring out how to do that is where Kristen is here to help us.

Upgrading from Liferay 6.1 to 6.2 Part 3

11 March 2016

In version 6.2 Liferay has made quite a jump to version 4 of Solr from 1.4 in use with Liferay 6.1. The Solr 4 setup for Liferay 6.2 is very similar to the setup for the previous version. First we will need to configure the Solr Portlet which gets deployed to Liferay. Second we will then need to configure and deploy the Solr server. This work is being performed on a XFCE Fedora Core 23 workstation. Software being used is Liferay 6.2 EE, Solr 4.9.1 and Apache Tomcat 7.0.68.

Recently there has been the need for me to revert changes in Subversion and to remove all unversioned files. This requires a few different Linux commands along with some Subversion commands.

Liferay: Internet Explorer (IE) and JSON Mime Type

09 April 2016

After upgrading to Liferay 6.2 we noticed that some of our portlets quit working in IE while still working with Firefox. Specifically those portlets relying on AJAX calls. Turns out, by default, Liferay 6.2 gives a MIME type “text/javascript” to JSON results delivered to IE. Results delivered to Firefox have a MIME type of “application/json”.
