Hello,
I it sort of working(code is below). My 2 problems are this:
1:If I put 2 components in the page editing the 2nd, edits the first and I
assume it is because it is always running the first form/zone as the names
of the second ones have _0 after it. I do not know how to get around this.
2:I still cannot figure out how to bubble the event to the page so I can use
the value on submit(IE save the object the field is a member of)
http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
${value}
public class AjaxEditor
{
@InjectComponent
private Zone zone;
@Parameter
@Property
private String _value;
@Property
private boolean _buttonfragment;
@Component(id = "value")
private TextField _valueField;
@Component(id = "form")
private Form _form;
@OnEvent(value = EventConstants.VALIDATE_FORM, component="form") public
Object validate() { if (_value == null ||_value.trim().equals("")) {
//validation errors _form.recordError("must have a fname"); return zone; }
else { return null; // let the form submission process continue } }
@OnEvent(value = EventConstants.SUCCESS, component="form") public Object
sucess() { // do whatever you want _buttonfragment = false; return zone; }
}
Thanks,
--James

Subject: Advanced Component help
Hello,
I am looking for a good tutorial(or help) on advanced components with forms
and event bubbling.
In particular a component that takes a value(with some paramaters) then
spits out a form with a form fragment inside a zone. When the user clicks a
button in this component the value parameter is to be changed and an
OnEvent caught to manipulate it. I am not even sure if this is.
Below is the code I would like to turn into a single value component(it is
basically an in place editor):
${firstName}
@InjectComponent
private Zone firstNameZone;
@Property
private String _firstName = "Fname";
@Property
private boolean _modifyFirstName;
@Component(id = "firstName")
private TextField _firstnameField;
@Component(id = "firstNameForm")
private Form _firstNameForm;
@OnEvent(value = EventConstants.VALIDATE_FORM, component="firstNameForm")
public Object validate() { if (_firstName == null
||_firstName.trim().equals("")) { //validation errors
_firstNameForm.recordError("must have a fname"); return firstNameZone; }
else { return null; // let the form submission process continue } }
@OnEvent(value = EventConstants.SUCCESS, component="firstNameForm") public
Object sucess() { // do whatever you want _modifyFirstName = false; return
firstNameZone; }
I would like the OnEvent to bubble through to the page.
Any nudge in the right direction would be appreciated.
