Making Autocomplete Form Stateless

I am really facing some hard time making Autocomplete Form statless. The problem basically stems from AutoCompleteBehavior which extends AbstractAutoCompleteBehavior which evetually extends AbstractAjaxBehavior. AbstractAjaxBehavior implements IBehaviorListener. I saw in the the Component class

Re: Making Autocomplete Form Stateless

Hi, I see you are not expert in Java either ;-) Your code suggestion will lead to StackOverflowError because it goes in infinite recursion. Wicket's Ajax behaviors are stateful. To be able to find the component that will feed the autocompleter the page should be preserved. There are some stateles

In this case you may need to implement org.apache.wicket.markup.IMarkupResourceStreamProvider to be able to provide dynamic markup. On Thu, Mar 8, 2012 at 1:04 PM, karthik wrote: > Hi Martin , > > "Reload the Table with New Columns" . > > How would i add the new column markup in my html page for

Hi, You can invalidate the http session. Since Wicket Session is an attribute in the http session it will be removed as well. On Wed, Mar 7, 2012 at 6:35 PM, Martin A wrote: > Hello, > I've got a REST service which is behind a Wicket Session Filter (due to the > need to obtain the wicket current

Dynamically sized image

Hey Guys I'm using an Image rendered with a DynamicImageResource (in this case a JFreeChart chart, but it could have been anything). I would like the image to fill the panel it is placed in which is sized relatively to the web page it is on. For the rendering to work I have to know the width and h

Re: Form with variable number of inputs

Thanks for the input Martin. Essentially, it's possible, but I'd have to rewrite form handling code and lose functionality :) Another idea: maybe it is possible to handle the variable number of form components with page parameters. Something like "http://&numPhones=n"; where "numPhones" wo

Re: Dynamically sized image

Hi, Maybe you do this with the WebClientInfo. See how http://www.wicket-library.com/wicket-examples/hellobrowser extracts client info like browser dimensions. You can use this information to calculate the size of the div and respetivelly the image that you have to generate. HTH On Thu, Mar 8, 20

GAE and file uploads

I've run to an issue with file uploads on GAE - after the file upload exceeds a certain size (~10k?), the default file upload implementation writes to disk, which is not allowed in GAE. I found this previous post: http://apache-wicket.1842946.n4.nabble.com/Wicket-and-FileUpload-on-Google-App-Engin

Re: Dynamically sized image

Hi Jarnis, We have a similar challenge: we determine pageable views' itemsPerPage based on available screen height. Since many of our pages have such views, we include JavaScript in each page that stores the current known height, and reports back any changes with jQuery (after a slight delay). wi
