How to dynamically obtains component's form id?
Hi,
Suppose I have a custom component built around a @TextField such that
I can drop this component inside any new @Form and it will magicall
work. From within my @TextField component I know nothing about the
host @Form, but I need to know it's ID at runtime. How can I do this?

Hi Adam,
sorry but I must be mistaken, probably you want to extend
org.apache.tapestry.form.AbstractFormComponent.
That should do?
Enjoy!

Thanks! That may be what I was looking for! But looking at the JavaDoc
for getForm it says:
"Returns the IForm which contains the component, or null if the
component is not contained by a form, of if the containing Form is not
currently renderring."
Well, my component is not contained in any form. It is expected to be
placed on a page (or another component) which provides a form for it.
So how can I implement this interface not knowing anything about the
form?

If you write a component which should work inside a form I think you're
supposed to implement the
org.apache.tapestry.form.IFormComponent interface, which has a getForm()
,method.

Not sure if this is in 4.0 officially, but TapestryUtils has a method
called:
public static IForm getForm(IRequestCycle cycle, IComponent component)
Which will return you the current form instance (assuming you are calling
this from a form component or any component contained by a form ).

I thing the only way to do this is iterate over all page components and look
for some
Form class component instance, as far as i know theres no direct way to get
the id from a component type, something like the DOM getElementByTagName
does (which could be graet!!)
Correct me if im wrong.
