Hi
This is a follow on from my previous email. I have decided that would
like to create a custom validator when a certain condition is met. In
this case, the validation checks if a value in is equal to an existing
field.
Here is a snippet of my flow script:
var validator = new
Packages.creative.validation.ParentRegionsValidation();
/* Keep showing form until it is validated and saved correctly to
the database */
while (true)
{
try
{
form.showForm("call-display-pipeline.jx", screenData);
var idx = 0;
var parentregions = form.getChild("parentregions");
while (parentregions != null && idx < parentregions.getSize())
{
cocoon.log.error("removing validator");
parentregions.getRow(idx).getChild("id").removeValidator(validator);
idx = idx + 1;
}
if (!isTopMost)
{
idx = 0;
while (parentregions != null && idx <
parentregions.getSize())
{
cocoon.log.error("adding validator");
parentregions.getRow(idx).getChild("id").addValidator(validator);
if
(parentregions.getRow(idx).getChild("id").removeValidator(validator))
{
cocoon.log.error("KamBha: Removed validator");
}
else
{
cocoon.log.error("KamBha: Validator was never
added");
}
parentregions.getRow(idx).getChild("id").addValidator(validator);
idx = idx + 1;
}
}
}
catch(e)
{
return;
}
I know that I have got the field I want to attach the validator to as I
had code to check the value of the widget, and it was what I expected. I
found that the validator does get added. If I move the showForm to after
I add the validator I get the following error:
2059002 2006-07-20 16:48:08,919 [http-8080-Processor25] ERROR
sitemap.handled-errors.prepareErrorHandler():165 - <map:call function>

org.apache.cocoon.ProcessingException: <map:call function> did not send
a response.
The following is my validator.
package creative.validation;
import java.lang.String;
import org.apache.avalon.framework.context.Context;
import org.apache.avalon.framework.context.ContextException;
import org.apache.avalon.framework.context.Contextualizable;
import org.apache.avalon.framework.logger.LogEnabled;
import org.apache.avalon.framework.logger.Logger;
import org.apache.cocoon.forms.formmodel.Widget;
import org.apache.cocoon.forms.validation.ValidationError;
import org.apache.cocoon.forms.validation.ValidationErrorAware;
import org.apache.cocoon.forms.validation.WidgetValidator;
public class ParentRegionsValidation implements WidgetValidator,
LogEnabled, Contextualizable
{
private Logger logger = null;
private Context context = null;
public boolean validate(Widget widget)
{
String regionId = (String)
widget.getForm().getChild("region_id").getValue();
System.out.println("In validate");
logger.error("In validate");
if (regionId.equals((String)widget.getValue()))
{
if (widget instanceof ValidationErrorAware)
{
System.out.println("validation error");
logger.error("Validation error");
((ValidationErrorAware)widget).setValidationError(new
ValidationError("Current region cannot be parent of itself"));
return(false);
}
}
System.out.println("No validation error");
logger.error("No validation error");
return(true);
}
public void enableLogging(Logger logger)
{
this.logger = logger;
}
public void contextualize(Context context) throws ContextException
{
this.context = context;
}
}
None of the print statements in the validator gets called when it is
working. I guess I understand why it wouldn't work when
call-display-pipeline is called before adding the validator, but I don't
understand why it would give me an error when I move it to the end. I am
using cocoon 2.1.7. If you need further code, I will give it. Any help
is appreciated.
Thanks
