Wicket Focus Policy
Hi,
had somebody implement a focuspolicy in wicket such as swings
focustraversalpolicy?
the policy should be analyzed in browser by default(a sorted list of
wicket-ids) because of performance. In some cases we need business-code to
evaluate next component. in this case we pass the determination via
ajax-callback (getNextWicketComponentID) to server-business code
Had somebody implemented this?
Are ther some tips, how to implement this policy myself?
thanks a lot alex

hi,
no, i think there doesn't exist an out of the box solution in any other
webframework.
you have to implmenent a visitor, which uses the java-programming policy
and:
- manipulates the htmlattributes for "static" fields
- add an ajax-behavior for dynamic fields.
i will implement this policy and present my first solution in a few days.
so long... alex

Re: Wicket Focus Policy

The chief problem in constructing pages with a consistent tabindex is
that you must:
1. Know from which parent component you are basing your numbering.
2. Handle ajax insertions of of components within your current
tabindex strategy.
Our current code has edge conditions where it fails, and is on our
short list of areas where we need a redesign. I am happy to work
with anyone on creating a more robust solution. Does anyone know how
or whether any other web frameworks implement a tabindex strategy?

Re: Wicket Focus Policy
Posted by "alexander.elsholz" <al...@widas.de>.
hi,
where is the difference?
yes, the html attribute tabindex helps to define a focus-policy. so i can
define a default policy and update the attribute with an ajax behavior.
i think a problem is the amount of updated components, when tabindices
changed because of business logic. her i could play with the index range
0-32767.
i try to implement a panel-based strategy and present the result in this
list.
thanks alex
