Tanks for the reply Jeremy.
Now that I knew what I was looking for, I found a lot of documentation
describing how to use $link & $jslink. Very useful indeed!
But I still hva a problem with the executrion order of the action event &
build?context methods.
As far as I can tell the behaviour is identical when using the following
form actions:
<form method="post" action="$jslink.getPortletById($portlet.ID)"
name="RundataTest">
<form method="get"
action="$jslink.getAction("portlets.test.general.Rundata_TestAction",
$portlet)" name="RundataTest">
Still the order is BNC-1, AE-2, BNC-2 and not AE-2, BNC-1, BNC-2 (whree
BNC is buildNormalContext and AE is the action event).
In this case the action paramter is added as ?action=xxxx.
Are the alternative ways to specify the action parameter in order to get
the action event executed before any context builds?

$jslink.getPortletById($portlet.ID)

If you want your action to fire first before any portlets are rendered,
you
will need to specify the action parameter in the url. This will cause
your
event to fire first.
