Newbie (possibly RTFM) issue
I am using Struts 2.1.6
if I have model like this:
public class model {
private Boolean testBool;
private boolean testbool;
...
public getters and setters for both follow
...
}
I find that in my corresponding jsp page (assumming that both testbool and
testBool are initialised to true and that private member 'model' is
available through its getter and a setter from within the action class)
evaluates to true, while
does not
I am highly suspicious that I may be doing something fundamentally wrong as
there is a complete absence of posts out there complaining about not being
able to evaluate Boolean.
Is there something I am missing here?
Any help is appreciated,
Regards,
C

Re: Newbie (possibly RTFM) issue
Sorry to report but does
nothing, also
renders nothing in the
resulting html page; now I know that testBool is 'true' because I am running
it through the debugger.
I am also runnning this under Java 1.6 so autoboxing should work as noted in
one of the previous posts.
I am completely lost for any other ideas..
Any help is greatly appreciated,

Re: Newbie (possibly RTFM) issue
Yeah, it's called isTestBool (but I tried with getTestBool as well) neither
work, I enabled the debug console adn if I output the stack values in my
browser is says that 'no read method is available, listing testBool as
'String' whereas the testbool (primitive boolean) is reported correctly as
'true' and is (ironically) of the right type 'Boolean' a this stage I thikn
it's definitely a Struts/OGNL issue
Cheers,
C.

Re: Newbie (possibly RTFM) issue
Haven't tried it (had to move on) I just reverted to primitives and rely on autoboxing (i.e. not having to make end to end change all the way to the server side) when passing model to my web service. newton.dave wrote: > > chumbobumbo wrote: >> Yeah, it's called isTestBool (but I tried with getTestBool as well) >> neither >> work, I enabled the debug console adn if I output the stack values in my >> browser is says that 'no read method is available, listing testBool as >> 'String' whereas the testbool (primitive boolean) is reported correctly >> as >> 'true' and is (ironically) of the right type 'Boolean' a this stage I >> thikn >> it's definitely a Struts/OGNL issue > > What happens when the methods are changed to isTestbool/isTestBool? > > Dave > > - > To unsubscribe, e-mail: user-unsubscr...@struts.apache.org > For additional commands, e-mail: user-h...@struts.apache.org > > > -- View this message in context: http://www.nabble.com/Newbie-%28possibly-RTFM%29-issue-tp24032216p24067129.html Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Struts Ajax Newbie
This is probably so basic - I'll put my flame proof suit just in case. I have a 2 combos and (yes ;-) I would like the second one to be loaded depending on what's been chosen in the first one, so in my action execute method I have: model.setList(service.getData1()); my struts.xml looks like this (note that I am using spring and I am hitting the same action 'class' (demoAction): jsp/output.jsp jsp/error.jsp jsp/second.jsp jsp/error.jsp in my output jsp I have: . that's all fine and dandy, but when I call loadSecond.action I find that my model is re-initialised anew (i.e. as the action is marked 'prototype' in spring config, the data for the first combo is no longer there) obviously I need data in the 1st combo to be available in the resulting page, as the user should be allowed to change the first selection (that would in turn relaod the second combo again). Is there a way to serialize/cache the data that was retrieved in the first call so that it is available in the subsequent call other than putting it in the session?

Re: Struts Ajax Newbie
Thanks for your help, however I think I may have miscommunicated, all I was
trying to find out is what is the 'currently acceptable' approach for
storing (and retrieveing) data between consecutive ajax calls seeing that
one always gets a brand new instance for any (and every) given action. Does
Struts provide some kind of mechanism other than http sesison to store
dependant data?
Thanks

Struts + Dojo problem
This is more of a dojo related question but since struts and dojo combination
is relatively common I thought someone may be able to tell me what's going
on here.
The problem is that dojo.event.connect doesn't like the element that is
referred in a second .jsp
(namely the line:
dojo.event.connect(ListB, 'onChange', 'listBEvent');
does not work as ListB comes in from listb.jsp, that is referred from
lista.jsp) - subsequently the 'listB' never fires listBEvent.
Is there anything that I am missing here or something that I may have
overlooked?
Any help is greatly appreciated.

Here is my setup:
struts.xml:
http://struts.apache.org/dtds/struts-2.0.dtd";>
jsp/lista.jsp
jsp/error.jsp
jsp/listb.jsp
jsp/error.jsp
jsp/listc.jsp
jsp/error.jsp
lista.jsp:
function listAEvent(event) {
alert("listAEvent [" + event.target.name + "]");
dojo.event.topic.publish("listAEvent");
}
function listBEvent(event) {
alert("listBEvent [" + event.target.name + "]");
dojo.event.topic.publish("listBEvent");
}
function init()
{
var ListA = dojo.byId('ListA');
dojo.event.connect(ListA, 'onchange', 'listAEvent');
var ListB = dojo.byId('ListB');
dojo.event.connect(ListB, 'onChange', 'listBEvent');
}
dojo.addOnLoad(init);
listb.jsp:
<%@ taglib prefix="s" uri="/struts-tags"%>
listc.jsp:
<%@ taglib prefix="s" uri="/struts-tags"%>
resulting html:
ListA
Selected
Code
Another Code
ListB
ListC
