Difference running web application on Debian and Windows XP

[Sergio <se...@strategos.com.br>]

Hi,

This will look like another common "Value is no String", but please read 
below what is happening. I get the following error when I publish my web 
application to debian server running apache-tomcat-5.5.17:

java.lang.IllegalArgumentException: Value is no String 
(class=java.lang.Integer, value=4) and component _idJsp46:smUnidadewith 
path: {Component-Path : [Class: 
org.ajax4jsf.framework.ajax.AjaxViewRoot,ViewId: 
/sjij/login/login.jsp][Class: 
br.com.strategos.faces.html.component.UIPage,Id: _idJsp0][Class: 
br.com.strategos.faces.navytheme.UILayout,Id: _idJsp1][Class:

does not have a Converter

I get no error when using Netbeans 5.5 on Windows XP Pro SP2 using the 
bundle Apache-Tomcat 5.5.17. The project was recently broke into smaller 
projects and that was when the error started to happen. I also tried 
Tomcat versions 5.5.26 and 6.0.16 on both computers (with debian and 
win.xp) and I get the same error on debian and but no error on windows 
computer. Currently I'm using tomahawk 1.1.6 and myfaces 1.1.5. Already 
tried things like full rebuild of the project, different versions of 
several libraries and checking the file encoding for my jsp files. Here 
are sample code from my java class:

private void loadUsuarioUnidades(){   
    this.listUnidades = new ArrayList<SelectItem>();
    for(SisUsuarioUnidade sisUsuarioUnidade : getUsuario().getUnidades()){
        setUnidade(sisUsuarioUnidade.getUnidade());
        getListUnidades().add(new 
SelectItem(getUnidade().getSeqUnidade().getValue(), 
getUnidade().getDesUnidade().getValue()));
    }
    if(getListUnidades().size() > 0){
        sortUnidades();
    }
}

And this is a sample from a JSP file:

<sh:selectOneMenu cols="2" label="#{msgs.UnidadeLabel}" 
value="#{basewebAcessoLogin.unidade.seqUnidade.value}" 
disabled="#{basewebAcessoLogin.notLogged}" >
    <sf:selectItems value="#{basewebAcessoLogin.listUnidades}" />
</sh:selectOneMenu>

I know someone will say: "Add a converter!". The problem is: this was 
not happening before and right now I have a huge enterprise application 
with about 230 web pages (some pages contains at least 1 combo box, some 
has like 4 or more combo boxes). Actually I already tried to add a 
converter to test on one of my web pages and the page started to work 
again on my debian server.

To make it more weird, this error does not happen on all combo boxes I 
use. And here is something to make even more weird I have one page with 
4 combo boxes on 2 different tabs (tabPanels) in a form a State/city 
dependency. When I select a state it loads the cities for that 
state...pretty simple huh? It goes fine on the first tab, but the second 
tab which loads the exact same data I get the IllegalArgument exception. 
The order on which I click, first tab or second tab, doesn't matter. The 
second tab always gives me the error.

Thanks in advance,
Sérgio
