Calculate property value on form submission
Hi, I've got a form with some fields, backed by an entity with a cpm. I've got one property on the entity which value is calculated in terms of one of the input fields in the form. It's important to have this field calculated up to date at form validation time. I tipically approached this issue by using an ajaxformcomponentupdatingbehavior to update the entity's calculated field on every change. Now i'm allowing non-js users into the site, and have mimed this action with a submit button. But, of course, the user might not press the button and go straight away without pre-calculating the value server-side. I've been thinking about binding a propertymodel to that calculated property, and somehow make it work like a model, so that its getObject will calculate the value, and thus have the value calculated before executing the form validator. Could you please provide any hint on how tho achieve this, if it is possible? Thank you very much! Xavier

RadioChoice keeps null rawInput after required validation?
Hi, I've got a form with a required radiochoice to select among some options. I've also got a yes/no radiochoice that selects a given option on rc1 and disables it when 'yes' is selected. When 'no' is selected, rc1 is set to enabled and its model object is cleared. The enabling/disabling of rc1 and its modelobject set is done in the onUpdate() method of an AjaxFormChoiceComponentUpdatingBehavior on the yes/no radiochoice. It's working fine, except in the following situation: 'no' is selected and rc1 has no value set. Then the required validation prevents the form submission. After that, if I select 'yes' on the yes/no radiochoice, it enables rc1 and sets its model object successfully, but, to my surprise, the input type=radio has no value selected when rendering the HTML. After debbuging through rc1#onComponentTagBody(), I've found that getValue() returns null, because rawInput is null (and not NO_RAW_INPUT), that's why there's no radio selected. I suspect rawInput is null because of last submitting rc1 with no value selected (when the required validation fails). I managed to get around this by calling rc1.clearInput() on the ajax behavior. Just want to know if i'm right about these thoughts, because I feel something wrong here, and if calling clearInput() is a good way of dealing with this. Thank you for your feedback! Xavier
Re: How to remove all previous pages from pagemap
Unless you completely invalidated the browser/client side cache of markup, people can still use the back button and will be presented with the markup as it was rendered at that time. It is not until the user performs an action at that page when wicket will try to retrieve the page from the page store. And only then will it see that the page is no longer available (provided the page was stateful, and the action URL is not targetting a stateless action) and present the user with page expired (or whatever you configured as the page expired page).

Re: How to remove all previous pages from pagemap
Hi Martijn Yes I know that, but as I stated, it's still possible to reload that page and perform actions on it (they are *all* stateful pages) - I must know how I can suppress that. I don't care if the user goes back and sees the page from the cache but he mustn't be able to perform any actions on it which I could not avoid yet, my knowledge of the page store implementation is too shallow; I don't know why the user may still access the previous page even thought I issued a Session.clear() which will call IPageMap.clear() on all pagemaps... Maybe because it's the previous page and it cannot really be removed .. ?

Re: How to remove all previous pages from pagemap
I now found one way to clear all previous pages. I guess the reason is the REDIRECT_TO_BUFFER strategy (or however it's called) which both processes a button's onClick() event AND the next page's full initialization+rendering in one request. Thus the previous page (where the button was) is marked as 'touched' in the Session as well - no matter when I clear all the pagemaps, the previous page will just be re-added at the end of the request. My current solution which solves this problem (although ugly) is the following code in the onClick: // Make sure this page does NOT get stored at the end of the request getSession().untouch(getPage()); // Clear all previous stored pages getSession().clear(); // display the confirmation page setResponsePage(new ConfirmationPage(...)); I still hope there's a better solution but this works for now Does anyone know if there's the possibility to override the REDIRECT_TO_BUFFER strategy for a certain redirect? This would also solve this problem as then the Session.clear() would be executed in the next request after the onClick() thanks Matt On 2011-01-25 18:14, Matthias Keller wrote: Hi List We've got the following scenario: After a user hopped through a wizard, he'll reach a confirmation page in our workflow.

How to deal with vertical tabs?
Hello, I have a problem with a Wicket Ajax response not being processed. Here the details: I have a link which is supposed to open a ModalWindow. The Ajax request is sent to the server, processed by the server, and the response is sent to the client. The client receives the response, including the HTML code for the ModalWindow and the JavaScript to open it. Nevertheless, the Wicket.Window.create call is never executed. After having investigated the problem, I have found out that this strange behaviour is triggered by a vertical tab character, which is an illegal XML character and causes the XML parser in Firefox and Chrome to exit (IE works though). This vertical tab character entered the markup from the application's data store and was part of the content of a data field. Until now, I came up with the following strategies: 1. One possible solution would be inhibition of illegal XML characters in the data. Besides the question, if this is semantically acceptable, it is difficult and sometimes not possible to intercept and clean all data entering the data store. 2. Another solution would be a Servlet filter, filtering all illegal characters. The problem I see with this solution is varying character encoding of the response, which makes it difficult to recognize the illegal characters in all circumstances. 3. My favourite solution would be some kind of mechanism in Wicket, which allows for filtering or modifying the data before the markup is rendered. I just do not know whether there is a way to do this in wicket and how to perform this task. Maybe you can help me and point me into the right direction. Other suggestions are welcome, too.

Martijn Hi Marijn Thanks for your reply Well, if the code's ugly or not is one side - the time required to get to that point is the other side - I spent hours trying to figure out why Session.clear() apparently does not work. To understand that, a lot of insight into Request Cycles, PageMaps and Render Strategies is necessary. I'd very much welcome a hook to alter the render strategy just for the next page. setRedirect(true) does not change the strategy and is the default in the (default) REDIRECT_TO_BUFFER strategy: In this case the next page is rendered and stored, then the user is redirected to a new url (to solve the Reload-after-POST problem) - the new url only serves the previously cached HTML code and does not call any hooks on the page itself (because it doesn't even know about it, I guess). So what I'd need would be a kind of setRedirect() which switches to REDIRECT_TO_RENDER. Matt smime.p7s Description: S/MIME Cryptographic Signature

FormComponentPanel and invalid child FormComponents question
I have a FormComponentPanel that represents a Time object - not java.sql.Time but my own Time object. This Time object has 2 fields - hours and minutes. The panel has textfields for the hours and minutes that are defined as class type Integer. I have a behavior on the panel that whenever it has error feedback messages it is added a css class that show a red border around it. This works when I explicitly call panel.error(some error). I do this when the hour field is empty and the minutes field has a value. But when I put an illegal Integer into the one of the textfields the feedback error message is registered with the textfield so the invalid-css-behavior doesn't trigger. Is there a simple way to tell a form component to register all of it's messages with some other form component - in this case the panel? Are there any other suggestion to get this desired behavior?

Class-only inheritance
Hi,
Is it possible to have class inheritance without markup inheritance?
I would like a wicket-aware base class (with an associated markup
file) with derived classes supplying data (e.g.. BaseClass with an
'abstract protected String getName()') and no markup files (or XML
files). I know how to do that if the derived classes have markup and
the base class markup has wicket:child, but cannot not figure out if
it can be done without the child markup.
So:
BaseClass.java (with abstract protected String getName(), and
add(new Label(name, getName()));)
BaseClass.html (with a span wicket:id=name/span)
BaseClass.xml
and the derived classes which extend BaseClass:
DerivedClass1.java (with protected String getName() { return
Class1;})
DerivedClass2.java (with protected String getName() { return
Class2;})
Currently, Wicket is trying to apply markup inheritance, but since
I don't have the markup for the derived classes I get:
org.apache.wicket.markup.MarkupNotFoundException: Markup of type 'html'
for component 'com.x.DerivedClass1' not found. Enable debug messages
for org.apache.wicket.util.resource to get a list of all filenames tried:
and
Caused by: org.apache.wicket.WicketRuntimeException: Expected to find
wicket:child/ in base markup
As a work around I can create a data supplier interface, implement
the equivalent of the two derived classes and pass those in to my
BaseClass, but the derived classes are simpler.
Thanks,
DC

if your DerivedClass1.java does not have markup and your

protected String getName()') and no markup files (or XML files). I know how
to do that if the derived classes have markup and the base class markup has
wicket:child, but cannot not figure out if it can be done without the
child markup.
So:
BaseClass.java (with abstract protected String getName(), and add(new
Label(name, getName()));)
BaseClass.html (with a span wicket:id=name/span)
BaseClass.xml
and the derived classes which extend BaseClass:
DerivedClass1.java (with protected String getName() { return
Class1;})
DerivedClass2.java (with protected String getName() { return
Class2;})
Currently, Wicket is trying to apply markup inheritance, but since I
don't have the markup for the derived classes I get:
org.apache.wicket.markup.MarkupNotFoundException: Markup of type 'html' for
component 'com.x.DerivedClass1' not found. Enable debug messages for
org.apache.wicket.util.resource to get a list of all filenames tried:
and
Caused by: org.apache.wicket.WicketRuntimeException: Expected to find
wicket:child/ in base markup
As a work around I can create a data supplier interface, implement the
equivalent of the two derived classes and pass those in to my BaseClass, but
the derived classes are simpler.
Thanks,
DC

Re: FormComponentPanel and invalid child FormComponents question
Hi Sam, you can change the feedback panel to show not only messages registered for the panel, but also for the inner components. The Wicket feedback panel uses the IFeedbackMessageFilter to filter what messages to display. You can provide one that test if the reporter is an panel children. See ContainerFeedbackMessageFilter On Wed, Jan 26, 2011 at 3:03 PM, Sam Zilverberg samzilverb...@gmail.comwrote: That is an excellent idea. However I don't want to just set the panel to be invalid when one of it's children is invalid. I'd like to also steal its' feedback message. I want this to happen because I have a feedback panel next to the form component that shows feedback messages registered to it. Is there a simple way to achieve this?

Here the details: I have a link which is supposed to open a ModalWindow. The Ajax request is sent to the server, processed by the server, and the response is sent to the client. The client receives the response, including the HTML code for the ModalWindow and the JavaScript to open it. Nevertheless, the Wicket.Window.create call is never executed. After having investigated the problem, I have found out that this strange behaviour is triggered by a vertical tab character, which is an illegal XML character and causes the XML parser in Firefox and Chrome to exit (IE works though). This vertical tab character entered the markup from the application's data store and was part of the content of a data field. Until now, I came up with the following strategies: 1. One possible solution would be inhibition of illegal XML characters in the data. Besides the question, if this is semantically acceptable, it is difficult and sometimes not possible to intercept and clean all data entering the data store. 2. Another solution would be a Servlet filter, filtering all illegal characters. The problem I see with this solution is varying character encoding of the response, which makes it difficult to recognize the illegal characters in all circumstances. 3. My favourite solution would be some kind of mechanism in Wicket, which allows for filtering or modifying the data before the markup is rendered. I just do not know whether there is a way to do this in wicket and how to perform this task. Maybe you can help me and point me into the right direction. Other suggestions are welcome, too.

setOutputMarkupId(true) on org.apache.wicket.markup.html.panel.Panel
I'm trying to understand what it means to output a markup ID on a reusable wicket panel. If I understand correctly, the wicket:panel element is removed from production markup and can contain elements that aren't necessarily wrapped in a single element (e.g. a div). So, what does Wicket do when you call setOutputMarkupId(true) on a Panel? Does it assume that you actually want to output markup IDs for all direct children of the wicket:panel element? This question came to light when I recently upgraded to Wicket 1.4.15. Since then, I've been getting the following warning messages: [org.apache.wicket.Component] Markup id set on a component that is usually not rendered into markup. Turns out I have some Panels that contain, among other things, a few wicket:container elements, which I use to output plain text via Labels (if there's a better way to do this, I'm all ears). Anyway, in my code, I'm not explicitly instructing the Labels to output markup IDs, but I am telling the Panel to. When I disable the call to setOutputMarkupId for the panel, the warning messages disappear, which leads me to believe that Panels actually set markup IDs for their direct descendants. However, looking through the Wicket source, I can't find any code to back up my assumption.

Re: setOutputMarkupId(true) on org.apache.wicket.markup.html.panel.Panel
calling setoutputmarkupid on a panel will output an id to the tag to which the panel is attached, eg add(new mypanel(foo)) div wicket:id=foo -- the tag that will have markup id output since you attach a panel to wicket:container tag and call setoutputmarkupid(true) on it, the id will never be rendered because wicket:container tag to which the panel is attached will not be rendered. -igor On Wed, Jan 26, 2011 at 12:50 PM, agilbert allen.gilb...@doane.edu wrote: I'm trying to understand what it means to output a markup ID on a reusable wicket panel.

Modify element attribute, preserve content

Use a WebMarkupContainer and add a SimpleAttributeModifier behavior to it. It will not touch the contents of the tag it's attached to, leaving your own html as it is.

Re: Modify element attribute, preserve content
Or, come to think of it, since you want to generate a href yourself on a link tag, use ExternalLink http://wicket.apache.org/apidocs/1.4/org/apache/wicket/markup/html/link/ExternalLink.html. Since it's a WebMarkupContainer underneath it will leave whatever is inside your a-tag intact.

Access to HttpServletResponse gone in 1.5?

I used to be able to access the servlet response object via: getWebRequestCycle().getWebResponse().getHttpServletResponse(); But now, expected to be able to use: ((ServletWebResponse)getResponse()).getHttpServletResponse(); But I get a ClassCastException because ServletWebResponse is wrapped a couple of times, i.e. by BufferedWebResponse and then again by HeaderBufferingWebResponse. And ... these wrapper classes do not provide an API to access the original wrapped response. How can I access HttpServletResponse? I am using a third party library that requires the Java Servlet API request and response object. Thanks.
