Hi,
By inactivity, I could also only refresh only the info box without the form
that's the correct solution.
Updating a text component (or its parent) via Ajax while it has focus will lead
to jumping cursors and/or lost user input.
Have fun

Hi,
thanks for your feedback.
My use-case is a text input field, that submits the form data on blur. But also
after an timespan of inactivity in the input filed itself (user stopped
writing).
The ajax response refreshed the form (invalidation messages) and in addition to
that an info box. Of course, the form refresh replaces the current input field
(that's the problem).
By inactivity, I could also only refresh only the info box without the form.
This could be a solution and maybe it is good enough.
An other approach (still updating the form) is to store and restore the value
(and focus, and cursor position) of the input field. I could use
AjaxRequestTarget.prependJavaScript() and AjaxRequestTarget.appendJavaScript()
for that.
I think I will try one of those two solutions.
Thanks for the help.

Hi,
from the JavaDoc:
/**
* Indicates whether or not this AjaxBehavior will produce
<ajax-response>. By default it will
* produce it but some behaviors may need to return their own response
which shouldn't be
* processed by wicket-ajax.js
*/
private boolean wicketAjaxResponse = true;
So with wicketAjaxResponse = false (attrs.wr = false) you can specify that your
code wants to handle the Ajax response instead of Wicket's default handling
(i.e. changing the DOM).
My goal is to prevent the ajax component replacement in some circumstances.
The circumstances could be changed during the delay between request and
response.
I don't see a solution how you could change .wr dynamically, since no event is
published before handling of the Ajax response.
What's your use-case?
Have fun

Hi everyone,
I've a question about the wicket ajax response processing.
What's the meaning behind the attrs.wr JavaScript boolean attribute?
I can change it with JavaScript by the IAjaxCallListener.getBeforeSendHandler()
method.
My goal is to prevent the ajax component replacement in some circumstances.
The IAjaxCallListener.getPrecondition() is to early. The circumstances could be
changed during the delay between request and response.
Thanks for any help.
