Hey all,
The problem I am having is setting the default state of a checkbox and
having the state retained over form submission.
If I set the default state to be selected (true in the underlying
actionform) when the form is submitted the checkbox remains selected even if
it has been de-selected before form submission.
If I set the default state to be not selected (false in the underlying
actionform) the state before submission is retained.
This wouldn't be a problem if the default state I required is to be not
selected, however Murphy's law does prohibit this and I need the checkbox to
be selected upon form entry. Code examples are provided below. If anyone can
help on this matter I would be most greatful as I can then stop banging my
head on the desk repeatedly. :)
I have altered the reset method, the initial value etc etc, but I just cant
seem to get this working.
Form:
public class KeywordSearchForm extends ActionForm
{
/**
* Member variables
*/
private String businessType = null;
private String businessName = null;
private String location = null;
private boolean serviceArea = true; //when this is set to false
everything works correctly.
private String suburbPostcode = null;
/**
* Getter and Setters
*/
public String getBusinessType() { return businessType; }
public String getBusinessName() { return businessName; }
public String getLocation() { return location; }
public String getSuburbPostcode() { return suburbPostcode; }
public boolean isServiceArea() { return serviceArea; }
public void setBusinessType(String businessType) {
this.businessType = businessType; }
public void setBusinessName(String businessName) {
this.businessName = businessName; }
public void setLocation(String location) { this.location
= location; }
public void setServiceArea(boolean serviceArea) {
this.serviceArea = serviceArea; }
public void setSuburbPostcode(String suburbPostcode) {
this.suburbPostcode = suburbPostcode; }
/**
* Validation Methods
*/
public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request)
{
ActionErrors errors = new ActionErrors();
validateBusinessParams(errors);
validateLocationParams(errors);
return errors;
}
//checks to ensure valid business information has been entered.
private void validateBusinessParams(ActionErrors errors)
{
if((getBusinessName().length() == 0) && (getBusinessType().length()
== 0))
{
errors.add("NoBusinessInfo", new
ActionError("error.businessInfo.required"));
}
}
//checks to ensure valid location information
private void validateLocationParams(ActionErrors errors)
{
if(("-1".equals(getLocation())) && (getSuburbPostcode().length() ==
0))
{
errors.add("NoLocationInfo", new
ActionError("error.locationInfo.required"));
}
}
public void reset(ActionMapping mapping, HttpServletRequest request)
{
this.businessType = null;
this.businessName = null;
this.location = null;
this.serviceArea = false;
this.suburbPostcode = null;
}
}
Action:
Nothing is going on here at all. Just a stub at the moment - processing to
be inserted later.
JSP:
<html:form action="/search/performKeywordSearch.do" focus="businessType">
<html:text property="businessType" styleClass="inputTxt"
style="width:215px" />
<html:text property="businessName" styleClass="inputTxt"
style="width:215px" />
<html:text property="location" styleClass="inputTxt" style="width:215px"
/>
<html:text property="suburbPostcode" styleClass="inputTxt"
style="width:215px" />
<html:checkbox property="serviceArea" />
</html:form>
Thanks in advance,
Sean
