Hi Michael,
That's a normal behavior. When you first check your
check box, your browser sends the value to your Struts application, and it
modify the corresponding property in your ActionForm. Next time, when you
uncheck the checkbox, no value is transmitted by the browser (empty values in
HTML forms are not transmitted), and your ActionForm property keeps set (if you
haven't removed it, but generally you don't if you want to display the other
properties...).
In Struts v1.0, there's a reset method that is
called just before initializing the form. From that method, you can decide to
reset all the checkboxes to their value from a database, for
instance.
If you're using v0.5, search in the mailing list
for different solutions (but incompatible with v1.0).

Subject: checkbox-problems ?
Hi,
I have a problem with JSP and using
Struts-checkboxes:
my code-fragement:
<struts:form action="editRules.do"
name="editRulesForm" type="org.apache.struts.example.EditRulesForm">
<div align="center">
<table width="100%" border=0 >
<tr bgcolor="white">
<th class="header" width="6%"><struts:message
key="entory.ruleEditor.active.header"/></th>
<th class="header" width="21%"><struts:message
key="entory.ruleEditor.ruleName.header"/></th>
<th class="header"
width="21%"><struts:message
key="entory.ruleEditor.attribute.header"/></th>
<th class="header"
width="12%"><struts:message
key="entory.ruleEditor.operator.header"/></th>
<th class="header"
width="21%"><struts:message
key="entory.ruleEditor.comparison.header"/></th>
<th class="header"
width="21%"><struts:message
key="entory.ruleEditor.mapping.header"/></th></tr>
<tr>
<!--I guess here is my problem -->
<td align="center"><struts:checkbox
property="isActive"></td>
<td align="center"><struts:text
property="ruleName" size="20"
maxlength="25"/></td>
<td align="center"><struts:select
property="attribute">
<struts:options property="values"/>
</struts:select>
</td>
<td
align="center"><struts:select property="operator">
<struts:options property="operatorValues"/>
</struts:select>
</td>
<td
align="center"><struts:text property="comparison" size="20"
maxlength="25"/></td>
<td
align="center"><struts:select property="mapping">
<struts:options property="files"/>
</struts:select></td>
</tr>
</table>
<table>
........
my problem seems to appear
with the <struts:checkbox>-tag
whenever I redirect my request to the JSP again, the checkbox is set,
it doesn't matter, if it was checked before or not.
Is there anything I'm missing ??
Any help would be appreciated.
Thanks in advance,
Mike
