----------------------------------------
Hi Musachy Barroso,
Let me send you the test case, so you can see it happens with you.
1o. Build a simple Pojo class into "org.apache.struts2.showcase.ajax" package:
package org.apache.struts2.showcase.ajax;
public class Pojo {
private Long Id;
public Long getId() {
return Id;
}
public void setId(Long id) {
Id = id;
}
}
2o. Than put a pojo attribute into the
"org.apache.struts2.showcase.ajax.AutocompleterExampleAction.java";
public class AutocompleterExampleAction extends ActionSupport {
private String select;
private List<String> options = new ArrayList<String>();
private Pojo pojo; // Pojo to reproduce the issue for the AutoCompleter bug.
:
:
:
}
3o. Than from the WebContent/ajax/index.jsp file, put a <s:textfield...> into
the "selectForm" form tag, this will work with the colors, fruit example;
Link two autocompleter elements. When the selected value in 'Autocompleter 1'
changes, the available values in 'Autocompleter 2' will change also.
<br/>
<form id="selectForm">
<s:textfield theme="simple" id="id" name="pojo.id" cssStyle="display:none"/>
<!-- This is for reproduce the issue -->
4o. Than run the server in debug mode, and place a breakpoint into the execute
method into the action class;
public String execute() throws Exception {
if ("fruits".equals(select)) { // put here a debug breakpoint
options.add("apple");
5o. Than run rebuild the showcase project and run it in debug mode.
6o. Go the "Ajax plugin for Struts"->"Autocompleter combobox tag ".
In this very moment the app will hang in the breakpoint, than look at
the Variables tabs from Debug perspective and colapse the "this" object,
you will see the value of the "select" attribute as null, then no matter
you try from the Autocompleter 1 field, been a colors or fruits, if you change
it
you will see the same thing into the debug.
That is the issue you need to fix, and it also happens for kind of
<sx:autocompleter implementation../> regarding silence submit by <s:url.../>
Conclusion:
I can make it works, but the fix for one thing will produce more issues, see
that:
1o. first change the <s:textfield.../> with "pojo.id" to <input type="hidden"
name="pojo.id"> into the index.jsp, than put the @SkipValidation anotation
right above the execute method from the action class
"AutocompleterExampleAction", build the project and run it again. You will able
to see it working, however this kind of fix, can build others issue for not
doing the validation.
Think about it, now you have what you ask, and I think it is very enough to fix
the bug.
I could done this, but I am very busy with my project and can't go deep into
this Dojo stuff.
Thanks and regards.

> Behave 3 at Firefox2.
> In both cases the attribute "select" was filled by the action.
> Now I'm stuck on that and asking for help for you guys.
> NOTE: If just use a <s:select...> component instead <s:autocompleter...> to
> select the "proposta.condicaoPagamento.id" and ignoring the <s:div...> thing,
> it just work as should.
