1. Re: portlet doView is called multiple times
peterj Apr 9, 2008 12:29 PM (in response to igorroyzis)It must be something about your portlet or configuration. I just tried it with one of my portlets and doView is called only once, even if the portlet is on a page by itself.
What version of JBoss Portal? What JVM? Could you post excerpts from the portlet-instances.xml and *-object.xml file, enough to identify the page, its portlet windows, and the corresponding instances. -

3. Re: portlet doView is called multiple times
peterj Apr 9, 2008 1:34 PM (in response to igorroyzis)I was using Portal 2.6.4 on AS 4.2.2. So I tried again with Portal 2.6.3 on AS 4.2.1. Still seeing only one call to doView.
You're using JDK 6. You like living dangerously. ;-) I was using JDK 5, tried with 6. Still only one call to doView.
And your configuration files are not much different from mine.
If I were you, what I would try next is adding this code at the start of the doView:
Exception eee = new Exception("called doView");
eee.printStackTrace();
Then you can figure out where each of the calls to doView is coming from. That might give some insight as to why it is being called multiple times. -

jssteux Apr 11, 2008 4:59 AM (in response to igorroyzis)We have exactly the same problem on JDK 1.5 / JBoss Portal 2.6.4. It concerns only the portlets which are positionned on the default page.

5. Re: portlet doView is called multiple times
peterj Apr 11, 2008 10:59 AM (in response to igorroyzis)I placed my portlet on the default page of the default portal, and on the default page of a new portal, and saw only one call. I still think the best bet is to look at the stack trace.

6. Re: portlet doView is called multiple times
peterj Apr 11, 2008 11:16 AM (in response to igorroyzis)One more thought - what framework are you using for your portlet? Spring? Seam? JSF? Struts? My portlet was a simple hello portlet using only JSPs.

igorroyzis Apr 11, 2008 12:21 PM (in response to igorroyzis)also simple jsp.

8. Re: portlet doView is called multiple times
igorroyzis Apr 11, 2008 12:23 PM (in response to igorroyzis)Jean, did you ever figure out what is causing the problem on your default page?

9. Re: portlet doView is called multiple times
mputz Apr 14, 2008 4:15 AM (in response to igorroyzis)Is this happening with the default theme/layout, or with a customized one?
I've seen multiple renderings with a modified jboss-portal.sar/portal-core.war/layouts/generic/index.jsp, which included the following:
- a *.js file with 'document.write(".......");' calls
- references to images where the URL starts with '/portal/content/....' (which is intercepted by the CMS stack) -
10. Re: portlet doView is called multiple times
tomhombergs Aug 14, 2009 3:56 AM (in response to igorroyzis)Have you ever found out what caused the multiple requests? I have the same problem: doView() is called 4 times although the portlet is only included one on the page.
What's more: i hacked into the LocaleInterceptor, which intercepts the HttpRequest and resets its locale-setting...it also gets called 4 times! JBoss Portal seems to make 4 requests out of one.
A different page containing the same portlets (and the same javascript) only gets called 1 time...I have no clue what triggers this behaviour. -
11. Re: portlet doView is called multiple times
tomhombergs Aug 14, 2009 7:00 AM (in response to igorroyzis)Found the reason for mutliple requests on http://www-01.ibm.com/support/docview.wss?uid=swg21242898.
Seems to be a general Portal issue and not JBoss-specific: if there is an -Tag on your page which links to a non-existing image, another page request is sent.
I found and corrected two such -Tags on my page and the number of requests was reduced by 2. -

tomhombergs Aug 14, 2009 7:01 AM (in response to igorroyzis)read "img-Tag" instead of "-Tag"...the forum stripped the html markup
