[jboss-user] [JBoss Portal] - Re: What is the format of renderURLs in 2.4?

[nollie]

(Everything that follows can be verified in org.jboss.portal.portlet.impl.PortletRequestDecoder.  I was reading code from the head of development, but everything I learned worked against my 2.4.1 installation)

Here are some example parameters I've found within my own application.

action=6&mode=view
action=a&windowstate=normal

6, a?  What does action mean?

Action isn't just any old parameter, its value is actually a hexidecimal number built from masks found in the PortletRequestDecoder.  The first bit, if on, indicates an actionURL.  The second bit, if on, indicates a renderURL.  The third bit, if on, indicates the URL has a mode parameter.  The fourth bit, if on, indicates the URL has a windowstate parameter.  Finally the fifth bit is used for the opaque mask, which we haven't figure out yet.  So, what does that give us?

Let's take look at the action=6 of the first parameter string.  6 in hex equals 110 in binary.  According to the bit assignments above that gives us:

  |      1 1 0
  | |_|_|_|_|_|
  |  o w m r a
  |  p i o e c
  |  a n d n t
  |  q d e d i 
  |  u o   e o
  |  e w   r n
  | 

Therefore this URL is a renderURL with a mode parameter.  Looking above the parameter string has a mode parameter equal to view.

Now let's look at the action=a of second parameter string.  A in hex equals 1010


  |    1 0 1 0
  | |_|_|_|_|_|
  |  o w m r a
  |  p i o e c
  |  a n d n t
  |  q d e d i 
  |  u o   e o
  |  e w   r n
  | 

Therefore this URL is also a renderURL, but this time with a windowstate parameter.  Looking above the example indeed has a windowstate parameter, but does not have a mode parameter.

What would the action need to be if we wanted to specify both mode and windowstate parameters?


  |    1 1 1 0
  | |_|_|_|_|_|
  |  o w m r a
  |  p i o e c
  |  a n d n t
  |  q d e d i 
  |  u o   e o
  |  e w   r n
  | 

 Binary 1110 is e in hex, so the URL would end something like this: action=e&mode=help&windowstate=normal.
