Agreed!
I can't reproduce the JIRA issue either.  It works for me...except in 
cases where it's obvious it can't work.

Hi,

I am a little stuck here. A action loads a jsp into a div. For this I 
use the ajax theme (dojo) and a form submit with target. Works fine. 
The Problem ist, that the jsp returned by the action has javascript in 
it. Its the jcalendar. Having this jsp load normally the calendar 
works fine, but not in div.


To solve this I tried executeScripts option, but that did not work. I 
searched and found out that eval might help, but I simply dont know 
how this could help.


Any hints would be greatly appreciated.  Many thanks in advanced!


Ensure separateScripts is also true.

Cut back the javascript to the bare minmial first (eg. an alert).  A lot 
of javascript has problems in this scenario because it assumes the DOM 
is complete or won't change before it's executed.  I think dojo updates 
the DOM, the executes discovered scripts, but in some browsers you can 
get race conditions.  eg. calls getElementById before that element 
exists properly (eg. exists and all its content exists).


The best approach is to use a listener that initialises the javascript 
calendar only after it's certain the DOM is up-to-date, rather than 
using inline javascript in the result..


Hope that helps.

Re: Validate associate Map

[Dave Newton]

On a vaguely-related side note, I spent yesterday floating in my kayak counting 
herons (1 great blue), egrets (4, species unknown), and, parenthetically, 
turtles, wondering where my bug spray was.

The variety in turtle size was astonishing; some were bigger than my head (I 
know, right?!) while others were smaller than the palm of my hand (but still 
managed to avoid me--apparently they can swim).

If I could just figure out a decent laptop mount for the cockpit I'd be all set.

Struts loses action configuration

[tjstavenger]

I'm using Struts 2.1.2 and Tiles 2.0.5 on WebLogic 9.2.1. Periodically I see
a TilesException in my server logs caused by a SocketException: Broken Pipe.
The next request made into Struts seems to lose the Struts action
configuration as I subsequently get a message "There is no Action mapped for
action name search_loadItemSearch. - [unknown location]". After these
errors, the application no longer works until I restart the server (I would
assume redeploying the application would work too).

I'm curious to know if someone else has seen a similar error or if anyone
has pointers as to places to start looking for the source of the problem and
potentially the solution??

Thanks!

Here's the stack trace from the SocketException:

Dude, I totally think technical books on audio would sell!  Most NERDS (like
myself) have the attention span of a moth and are so busy chasing shiny
things they can never get to the end of a book!  I would slam an aBook in my
iPod for the commute.  For a great example of what I mean by attention span
disorder, check this  out.

Dear Gainty,

vielen Dank for your reply. I am very sorry but I cant supply you with a 
url. What I load into the div is the following:


<%@ include file="/common/taglibs.jsp"%>

   
   ..
   
   

src="${ctx}/scripts/calendar/calendar.js">
src="${ctx}/scripts/calendar/calendar-setup.js">
src="${ctx}/scripts/calendar/lang/calendar-${pageContext.request.locale}.js">


   Form.focusFirstElement(document.forms["traitForm"]);
   Calendar.setup(
   {
   inputField  : "form_start",  // id of the input field
   //ifFormat: "%m/%d/%Y",  // the date format
   ifFormat: Calendar._TT['TT_DATE_TIME_FORMAT'],
   showsTime   : true,
   singleClick : false,
   button  : "button_start"// id of the button
   }
);


I use the following technique to load it into the div:


   
   

  

   cssStyle="width: 100%;"
   loadingText="getText('Loading')" >


The selectTraitPage-action returns the jsp with the jcalender. The 
problem is, that clicking the button than does not result in a calendar 
view. I can use it when loaded not in the div.


I simply dont know why and are very grateful for your help. I believe 
its a matter, that the imported calender.js and/or prototype.js (which 
is needed for the calendar) can bind to the button!? So it fails.


Thx,
Henning
