Liferay 6.2 is nice, but the guys working on the themes, should make a time travel in the past and use bootstrap 2.3... They don'y like it at all.
Lets us assume we want to have an admin portlet in the content area in our site. We can do this by adding the following xml elements in the liferay-portlet.xml
If you are working in a custom portlet and with FileEntries, it is very likely that you will need the preview url of this file, to use it in your UI.
When a kaleo workflow in Liferay 6.2 sends an email, it adds automatically as the sender the email firstname.lastname@example.org. If you want to change that, you can't...
You can do this by adding p_p_parallel=0 in the URL.
In the past I tried to find out how to unit test my plugins in liferay with no success. To be honest, I never tried much, and I am also a rookie in unit testing.
