JSON Response from DirectLink Help
Hi All,
Probably a simple answer to this but I'm lost; how do I get a JSON
response from a link? And once I've got a response how does it get
procesed;
ie: User clicks a link, ajax call is made, a JSON object is created
and returned, a method then fires to process the recieved JSON object.
Ive had a look at the Autocompleter and its just confused me.
I've got this far:
public void jsonTest(IRequestCycle c){
// err now what?
// c.getResponseBuilder().getWriter() returns NullWriter
}
providing a json object gets back to the browser how does the
response get handled?
Many thanks,
Adam.

Re: Checkbox required validation not working
OK, I've implemeted Scotts code but I'm still not getting any
validation.
Reg.page
class="com.azudio.tapestry.validator.RequiredCheckbox">
I've put some debugging statements into the RequiredCheckbox class
but it seems that when the page with the required checkbox is
rendered the 'renderContribution' method never gets called, therefore
no javascript gets output. Also when if the checkbox is left
unchecked and the form submitted the 'validate' method also does not
get called, only if its checked does 'validate' get called.
Thanks,
Adam

Hi Adam,
The required validator generates client-side javascript that
calls the
Tapestry.require_field function. This is the code of that function:
Tapestry.require_field = function(event, fieldId, message)

var field = this.find(fieldId);
if (field.value.length == 0)
event.invalid_field(field, message);
}
Problem is, for a Checkbox field, the value of the checkbox is
either true
or false, so is thus never empty. Hence it always passes the
require_field
test.
I wrote my own RequiredCheckbox validator as follows:
RequiredCheckbox.java
public class RequiredCheckbox extends Required {
public void validate(IFormComponent field, ValidationMessages

throws ValidatorException
{
super.validate(field, messages, object);

{
String message = buildMessage(messages, field);
throw new ValidatorException(message,

}
}
private String buildMessage(ValidationMessages messages,
IFormComponent field)
{
return messages.formatValidationMessage(
getMessage(),
ValidationStrings.REQUIRED_FIELD,
new Object[]

}
public void renderContribution(IMarkupWriter writer,

BooleanValidator.js
Tapestry.require_boolean_field = function(event, fieldId, message)
{
var field = this.find(fieldId);

context.includeClasspathScript

StringBuffer buffer = new StringBuffer("function(event) {
Tapestry.require_boolean_field(event, '");
buffer.append(field.getClientId());
buffer.append("', ");
buffer.append(TapestryUtils.enquote(buildMessage(context,
field)));
buffer.append("); }");

}
}
BooleanValidator.js
Tapestry.require_boolean_field = function(event, fieldId, message)
{
var field = this.find(fieldId);
if (!field.checked)
event.invalid_field(field, message);
}
Then you use it in your page file like this:
Home.page
class="com.myapp.validator.RequiredCheckbox">
Hope this helps.

Re: Checkbox required validation not working
No difference, I changed the form to: listener="listener:confirm"> T&C:validators="validators:required"/> On 24 Jun 2006, at 13:33, James Carman wrote: What happens if you take the listener off the button and put it on the form itself. -Original Message- From: Adam Henderson [mailto:[EMAIL PROTECTED] Sent: Saturday, June 24, 2006 8:23 AM To: Tapestry users Subject: Checkbox required validation not working Hi All, I'm doing a simple form that has a checkbox which must be checked in order to submit the form: clientValidationEnabled="ognl:true"> T&C: but if I can still submit my form without the checkbox being checked, so it looks like no validation is taking place.
