Re: Models, and preventing obsolete objects being manipulated by Ajax requests
Each component can have as many models it needs. For an example see ListChoice which has one model for its selection and a second one for the available choices. Wicket's Component base class has a default model, which offers convenience (it's automatically detached after request) and some other goodies (i.e. inherited models). Read more here: https://cwiki.apache.org/WICKET/working-with-wicket-models.html >Page#setDefaultModel( new PropertyModel( this, "user" ) ); And then in on* methods, >I should use getPage().getDefaultModelObject(). Models offer no magic: Doing the above versus just directly accessing the page's property doesn't change much (depending on what "this" is referring to). >Is that correct, or should I look for some other bug in my code? Your components are probably holding references to different User objects. Cleaning up your code using models might help.

Hi, I don't like switching a and ... so I take (IMO) better approach: Style the or a so it looks like a label - i.e. no border, transparent background, inherited font.

Re: Problem in implementing user confirm modal while deleting something..
To add my 2 cents: Confirmatory modal dialogs suck. I rather put a hidden bright red button next to the one which deletes, and on click, I show this red button which actually deletes. So the user 1) doesn't have to travel the mouse around the page too far 2) can't accidentally press space or enter to confirm. 3) With AjaxFallback..., it doesn't need JS.

I would redirect to that page, and inform that processing this or that failed. Of course, the app shouldn't leak exceptions like that and they should be caught at right places... But that's a perfect state, and until that's reached, this could make the app a bit more robust. But having just the exception is good enough. Ondra

Models, and preventing obsolete objects being manipulated by Ajax requests
Hi, I have observed that if I simply refer to Page object's (say, User) member field everywhere, sometimes I get a strange behavior: Ajax requests update the User object properly. But then I have non-ajax save (submit) button, and this one actually saves the old state of the object, before editations. I get it I am supposed to use models in this case, like, Page#setDefaultModel( new PropertyModel( this, "user" ) ); And then in on* methods, I should use getPage().getDefaultModelObject(). Is that correct, or should I look for some other bug in my code? And also, what does the "default" mean in the methods names getDefaultModel*() ? Can the page/component have multiple models?

Re: Centralizing ajax inline javascript
actually i have the elegant solution for your problem in 6.x ,i didn't recommend it before because you are on 1.4 i wrote Quickview and QuickGridView ,the whole project is available at https://github.com/vineetsemwal/quickview including examples. the way of using QuickView is almost like DataView the way of using QuickGridView is almost like Gridview what they offer is they can add/remove new items/rows without the need to repaint the whole repeater.i have written a navigator and a scroll behavior for that so on demand/scroll you can add new rows.this in working is like how new rows are added on demand/scroll in social networking sites.a user practically doesn't have to learn anything. the problem is i don't want to port/support any version less than 6.x On Fri, Sep 28, 2012 at 8:34 PM, lukuperman wrote: > Hi Vineet.

Hi Vineet. I knew someone would ask. Lots of components right? Yes, I agree. The component tree is giving us a hard time with performance in general (around 5 minutes to process) and stack overflows when serializing, etc. But focusing back to my original question, unfortunately the business requirement remains. Pagination is not allowed. The page is currently loaded at once, but lazy loading is certainly an option if end result is the same. I'll search for ajax scroll behaviors.

Re: Centralizing ajax inline javascript
Yes, I think the AbstractDefaultAjaxBehavior could look to something like:
public void renderHead(Component component, IHeaderResponse response)
{
super.renderHead(component, response);
response.renderJavaScript("function boup(id) { " +
this.getCallbackScript() + " }", "my-script-id");
//TODO: where (id = 10)
}
protected CharSequence getCallbackScript()
{
return this.generateCallbackScript("wicketAjaxGet('" +
this.getCallbackUrl() + "&id=' + id"); //warning, do not close script with
")"!
}
protected void respond(AjaxRequestTarget target)
{
final IRequestParameters parameters =
RequestCycle.get().getRequest().getQueryParameters();
int id = parameters.getParameterValue("id").toInt();
//TODO: do something with id
}

Re: Centralizing ajax inline javascript
assuming you are using a repeater say dataview/gridview,think about that in this way 200*200==40k items of repeater,are you rendering that number of items at once? i would have used a small table with navigator or some ajax scroll behavior ..

Centralizing ajax inline javascript
Hello all, I am working on an application that was built with Wicket 1.4.15. It has to show a table with an AjaxCheckBox on each cell. Most of the final html size is because of the inline ajax behavior on each cb (ie 20Mb for a 200x200 table). Leaving aside the fact of rendering big tables (which is imposed by business), can you give me some hints or ideas on how can I decrease final html size maintaining ajax behavior? For example, how can I: -centralize the javascript and make checkboxes call it passing the minimum parameters needed (id, etc) -or event registration, without migrating to Wicket 6 (not allowed to) -some other way?

Re: edit label w/o ajax
I don't know if it already exist but I would do the following to implement it 1-Make a component that contain both a label + plus the edit field 2-Edit field and View component are always present but visibility is toggled via JavaScript (at client side). 4-When user choose edit, view field is made hidden via JS and edit field is shown (also via JS) 4-When user finish editing, edit field is submited via AJAX, then edit field is hidden, via JS, and view field is shown (maybe returned as JS "action" on AJAX call). This should not be that difficult to implement (I guess).
