Hi Alex!
Have you solved your problem yet? I was facing the same situation a cuple of weeks ago.
All values from your formbean are sent in the request as parameters when you
press submit - but checkbox values are only in the request if they have the
value on = they are checked. The reset method works like this: values are first set
to false by the reset method and then, if they are present i the request they receive
value true, otherwise the have the value false.
Is your problem the following: when you come to your second page the values are
correct but when you submit this page you go to an action class that forwards to the
first page - is that correct or do you go via two action classes to reach the first
page from the second page?
Anyway, since the formbean values are present as parameters in scope request, they are
not found the last time the reset method is called. First the reset method sets the
checkbox values to false, after that no parameters are found in the request and thats
way the final checkbox value is false, even though it was true on your second page.
I solved this problem by checking the formbean's checkbox values in the first action
class after my second page and when I forwarded to a second action class before my
first page was shown again I added parameters to the requset manually if the checkbox
value was on = true. When the reset method was called these parameters were found and
the formbean was populated in a correct way.
Good luck / Linnéa
By the way:
A while ago someone sent an alternative version of the doStartTag that should solve
the checkbox problem: new version for doStartTag() method :
public int doStartTag() throws JspException {
// Create an appropriate "hidden" element to put it before the "input" element
// with value false. This will force to uncheck in the ActionForm if the checkbox
// is not checked
StringBuffer resultsHidden = new StringBuffer("<input type=\"hidden\"");
// Create an appropriate "input" element based on our parameters
StringBuffer results = new StringBuffer("<input type=\"checkbox\"");
resultsHidden.append(" name=\"");
results.append(" name=\"");
// Indexed properties handling
if (indexed != null) {
IterateTag iterateTag =
(IterateTag) findAncestorWithClass(this, IterateTag.class);
if (iterateTag == null) {
// this tag should only be nested in iteratetag, if it's not, throw
exception
JspException e =
new JspException(messages.getMessage("indexed.noEnclosingIterate"));
RequestUtils.saveException(pageContext, e);
throw e;
}
if (name != null) {
results.append(name);
resultsHidden.append(name);
}
results.append("[");
results.append(iterateTag.getIndex());
results.append("]");
resultsHidden.append("[");
resultsHidden.append(iterateTag.getIndex());
resultsHidden.append("]");
if (name != null) {
results.append(".");
resultsHidden.append(".");
}
}
// End of Indexed properties handling
results.append(this.property);
results.append("\"");
resultsHidden.append(this.property);
resultsHidden.append("\" value=\"false\" />");
if (accesskey != null) {
results.append(" accesskey=\"");
results.append(accesskey);
results.append("\"");
}
if (tabindex != null) {
results.append(" tabindex=\"");
results.append(tabindex);
results.append("\"");
}
results.append(" value=\"");
if (value == null)
results.append("on");
else
results.append(value);
results.append("\"");
Object result = RequestUtils.lookup(pageContext, name, property, null);
if (result == null)
result = "";
if (!(result instanceof String))
result = result.toString();
String checked = (String) result;
if (checked.equalsIgnoreCase("true")
|| checked.equalsIgnoreCase("yes")
|| checked.equalsIgnoreCase("on"))
results.append(" checked=\"checked\"");
results.append(prepareEventHandlers());
results.append(prepareStyles());
results.append(">");
// Print this field to our output writer
ResponseUtils.write(pageContext, results.toString() + resultsHidden.toString());
// Continue processing this page
this.text = null;
return (EVAL_BODY_TAG);
}
