------------------------------
Summary: Spurious "Unexpected Exception caught setting" message
from com.opensymphony.xwork2.interceptor.ParametersInterceptor on checkboxlist
tags
Key: WW-3939
URL: https://issues.apache.org/jira/browse/WW-3939
Project: Struts 2
Issue Type: Bug
Components: Plugin - Java Templates
Affects Versions: 2.3.7
Environment: Centos/Apache/Tomcat
Reporter: Greg Huber
Priority: Trivial
Hello,
There is another spurious "Unexpected Exception caught setting" message that
comes from the use of the checkboxlist tag as it renders its hidden field with
the id beginning with "__multiselect_".
com.opensymphony.xwork2.interceptor.ParametersInterceptor line starting 314
{code:java}
for (Map.Entry<String, Object> entry : acceptableParameters.entrySet()) {
String name = entry.getKey();
Object value = entry.getValue();
try {
newStack.setParameter(name, value);
} catch (RuntimeException e) {
if (devMode) {
String developerNotification =
LocalizedTextUtil.findText(ParametersInterceptor.class, "devmode.notification",
ActionContext.getContext().getLocale(), "Developer Notification:\n{0}", new
Object[]{
"Unexpected Exception caught setting '" + name +
"' on '" + action.getClass() + ": " + e.getMessage()
});
LOG.error(developerNotification);
if (action instanceof ValidationAware) {
((ValidationAware)
action).addActionMessage(developerNotification);
}
}
}
}
{code}
It may be the way I am using the checkboxlist (list of checkboxes in a table),
but if I add to the id & name attributes the "cnt" number on the checkboxlist
tag to match the id on the select tag the error message goes away?
ie add + "-" + Integer.toString(cnt) below:
CheckboxListHandler (on the javatempaltes tag!)
{code:java}
//Hidden input section
a = new Attributes();
a.add("type", "hidden")
.add("id", "__multiselect_" +
StringUtils.defaultString(StringEscapeUtils.escapeHtml4(id))+ "-" +
Integer.toString(cnt))
.add("name", "__multiselect_" +
StringUtils.defaultString(StringEscapeUtils.escapeHtml4(name))+ "-" +
Integer.toString(cnt))
.add("value", "")
.addIfTrue("disabled", disabled);
start("input", a);
end("input");
{code}
output code:
<input id="favourites_idEmails-1" type="checkbox" value="test" name="idEmails">
<input id="__multiselect_favourites_idEmails-1" type="hidden" value=""
name="__multiselect_idEmails-1">
####
The freemarket template may also need the modification to the hidden field, ie
add -${itemCount} to the id/name
<input type="hidden" id="__multiselect_${parameters.id?html}-${itemCount}"
name="__multiselect_${parameters.name?html}-${itemCount}"
value=""<#rt/>
Cheers Greg
