Re: [t5.2.6] Composing pages through inheritance problem

2011-09-28 Thread Muhammad Gelbana 
I know you mean I should use components but in what way ?
I retracted the inheritance approache and replaced it with the
switchingidea which
is marvelous. This way I won't get into the messy "t:if" tree.

I'm trying to figure out *every possible way* of composing pages from
components, that's why I asked you what do you mean :)
And this way I'll learn more about components till hopefully reach the point
when I say "Now I get it !" :)

For example consider this case, what if I want to have the blocks in the
switching example, to be in a separate .tml file ? Just to reduce the page's
size and make it easier to maintain.

Actually I can apply this idea to the common test fields part. It's a bean
editor declaration in the page's .tml file:
**
* *
* *
* *
* *
* *

Is it possible to get this bean-editor's declaration from another .tml file
? I tried extending the bean editor component, but I couldn't figure out
what to put in the .tml file ! Can mixins fit in ?

I'm all about trying everything and mastering this very flexible and nice
framework, that's why I'm asking too many questions :)

Thank you for your time :)

Re: [t5.2.6] Composing pages through inheritance problem

2011-09-28 Thread Taha Hafeez 
Hi Muhammad

I don't think inheritance is the best approach with tapestry. You can
always re-factor your code by composition. Using components is always
a better approach.

If you have a child page trying to access a component in parent page,
IMHO, you should reconsider your refactoring.

[t5.2.6] Composing pages through inheritance problem

2011-09-28 Thread Muhammad Gelbana 
This is a new approach I'm taking to compose pages. I'm trying to convert an
existing application to tapestry but one page turned out to be really big
and hard to maintain. This page has many form fields. Some fields should
always exists, and conditionally show other fields depending on a condition,
let's say a "test type".

I used to do this in one page template, then conditionally showing the
fields I want using the "t:if" component and a configured bean-editor
inside.
Then I decided to go more scalable so I decided to make a page for each
"test" and inherit the page with the common fields. This will release me for
the messy "t:if" "p:else" tags all over the center of the page.

Now I'm facing an issue that my parent page has injected components
(@InjectComponent) and when displaying the child page, it complains:
Component tests/DNSTest does not contain embedded component 'gatewayField'.
The "gatewayField" variable exists in the parent page as:
@InjectComponent
private TextField gatewayField

..and there are other fields. I tried adding @Property, and getters\setters
my self, still didn't work. It only worked when I commented these fields and
code referring to them.

How can I resolve this ? And is this the best approach to dynamically
construct a page ?

Thank you all for your time :)
