Doubt about basic portlet concept
Hi all,
I've created a portlet application containing a portlet that extends
IFramePortlet to navigate to an specific URL... and I've included the
portlet in two different psml pages in order to refer two different URLs
at the same time...
As far as I know, I would expect to have two different and independent
instances of the portlet class (created by the portlet container), but I
think they are totally messed up...
For example, the portlet gets the portal user who is accessing the
portlet and saves it to a private attribute, so before any user has
logged in i can see that is a guest user who is accessing the portlet...
Then i register as a new user and try to view the portlet content. I can
see that the previous user was "guest" and also the username of the new
user... But then i go to see the content of the other portlet and it
says that the previous user was "username" (where i would expect to see
"guest") and actual user is also "username"...
I don't know if I've explained my problem properly...
Supposed:
* Portlet A (in psml page A)
* Portlet B (in psml page B)
Situation 1 (nobody has logged in yet, but we're viewing "Portlet A"):
* Portlet A:
o Previous user: null
o Actual user: null
* Portlet B (is supposed to display the same info)
Situation 2 ("user1" logs in and asks portlet A to render):
* Portlet A:
o Previous user: null
o Actual user: user1
* Portlet B ¿?
Situation 3 ("user1" asks portlet B to render clicking on page B tab):
* Portlet A: ¿?
* Portlet B:
o Previous user: user1
o Actual user: user1
But since "Portlet B" has not been asked to render yet, I would expect
it to show "null" as previous user...
So I guess both portlets are modifying the same instance, and maybe
that's the reason why I'm having problems displaying the URL content...
=/ (Both are trying to display the same page...)
Does anybody know how many instances should be created? Can anyone give
me some insight in the matter?
Thanks in advance and regards.
PS: sorry for my English

Hi Aaron,
The fragments I have are:
<fragment id="prueba-p-5" type="portlet"
name="Test_1::Alfresco_WebClient_Portlet">
<property layout="TwoColumns" name="row" value="3" />
<property layout="TwoColumns" name="column" value="0" />
<!-- Portlet Preferences -->
<preference name="ALFRESCO_SERVER_ADDRESS">
<value>localhost</value>
</preference>
<preference name="NODE_UUID">
<value>81ac88b1-c031-11db-8d91-6d811b5c1f39</value>
</preference>
<preference name="height">
<value>600</value>
</preference>
</fragment>
<fragment id="cms-p-2" type="portlet"
name="Test_1::Alfresco_WebClient_Portlet">
<property layout="OneColumn" name="row" value="0" />
<property layout="TwoColumns" name="column" value="0" />
<preference name="height">
<value>800</value>
</preference>
</fragment>
So I guess they have different id's...
I don't know... maybe the problem is something related to the cache
(browser cache, j2 cache, portlet cache or alfresco cache...)
Regards.

Enrique,
what are the fragment IDs that you are using in your PSML pages? Are
they the same value? If so, that is your problem...
