[Wicket-user] SortableDataProvider, size() iterator(int first, int count), Correct execution order?
Hi, there, I have the following composition: WebPage ... ... DataView CustomProvider extends SortableDataProvider ... PagingNavigator DataView The ERROR? I found is this: When clicking on any of the navigation buttons (PagingNavigator), my CustomProvider implementation is managed by Wicket FW calling its implemented (abstract in SortableDataProvider) in the following order: 1 size() 2 iterator(int first, int count) That causes wrong results, because it calls first the size() to check the results obtained when I havent called the iterator(...) yet, and inside my implementation of iterator(int first, int count) I obviously do the call to the API that accesses to my persistent layer obtaining the results according to the specified (first, count) pair... So, what happens in practice... that when navigating the size() method retrieves the before obtained iterator.size(), and not the new one that will be obtained immediatly after it, when calling to iterator(...). So, if the order was this: 1 iterator(...) 2 size() The problem would be solved... Please, would you mind explaining my how to resolve this issue? Thank you! M - Take Surveys. Earn Cash.

[Wicket-user] Why does setResponse sometimes does notResponse?
Hallo, I have this web-flow sequences (two branches to the same leaf): [web-flow 1] WebPage1 WebPage2 [+Applet] WebPage3 [web-flow 2] WebPage1B [+Applet] WebPage2 [+Applet] WebPage3 The Applet is the same in all cases: is an Applet that digitally signs (windows keystore for certs) and automatically launches a javascript event onSignOK(), which does document.formNavigateToPageX.submit(). When trying web-flow 1 things work perfect: first navigate to Page1, then click-on-link and navigate to Page2, which internally checks digital signature, and in case OK it automatically navigates to Page3, by means of setResponse(Page3). That works fine. But the other web-flow 2 does not: navigate to Page1B, internally checks digital signature, and in case OK it navigates to Page2 by means of setResponse(Page2). That works fine... but when then arrives Page2, it internally checks another digital signature, and in case OK it should navigate to Page3.. but not. Internally it also does a setResponse(Page3)... but after the constructor endes, nothing happens... it executes and renders, and the flow dies at Page2. Any idea what can be wrong here? Dankeschen!

[Wicket-user] Why does setResponse sometimes does notResponse?
you shouldnt be calling setresponsepage inside constructors try RestartResponseException Yes, RestartResponseException forced it to response fine. Anyway, it's a shame setResponse sometimes fails in constructors, I already have other web-flows working fine with it. That's because I have some flow-decision-logic concentrated in constructors (logic-convergence reasons) instead of previous page's end-points (links, buttons, etc). May should I extract that constructors logic-convergence to be processed appart in a Switch class that may accept a WebPage parameter to then internally call its setResponse, so avoid logic in constructors and then call this Switch class at the end-points. I guess that maybe this will not be applicable in all cases, but could try. - Take Surveys. Earn Cash.

Re: [Wicket-user] Why does setResponse sometimes does notResponse?
available, and I cannot think of a good end-user reason why this couldn't be called. The getMarkupId method can in fact be called in if it is possible to make every method work at constructor, of course this is not necessary. It's a good idea to shield people from errors that aren't immediately clear until runtime. Instead of that, wouldnt it be easier to make setResponse work forcibly in construction time similar as RestartResponseException does when explicity called? cancelling current page creation ( its component-tree) and force flow to the new page before responding... - Take Surveys.

[Wicket-user] onGoingBack2Page(+innerForm) = innerForm.fields = empty!?
Dear Sirs, The scenario is the following: - Page1 Form1 (innerClass) input1(String)... inputN(String) - Page2 Link/Button (whatever for going back to Page1 - has a reference object of Page1) ... - PageN Link/Button (idem) It happens that, when flowing-back from Page2, or... PageN, to Page1, then Page1 displays but with all innerClass-Form1 fields empty! The state of other things in Page1 keep there, but all the state of fields in Form1 has desappeared. What's wrong here, any idea? Regards. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits. Just data.

Re: [Wicket-user] onGoingBack2Page(+innerForm) = innerForm.fields = empty!?
Actually the flow page1ToPage2 it's done by form submission, i.e., all form is correctly processed. The matter was when going back from Page2...N to Page1. It was happening that the inerForm page1.Form1 was not keeping state (fields were null). After reviewing the code, I noticed that I was keeping a reference of Page1 in Page2...N, but Page1 is not a direct WebPage, but a custom extension of it. Then, what I did was just keeping the reference in Page2...N as a pure WebPage (implicit upcast), and then worked fine. So, it seems that the framework didn't like me to use the custom extension to keep the reference of Page1; just the WebPage.

[Wicket-user] Applet not loaded in 1.2.6, but in 1.2.5, and viceversa, depending on codebase [jetty-server]
Dear people, I have found the following strange behavior in wicket-1.2.6: Since long time ago I've been using wicket-1.2.5, and testing a webPage where there's an applet with the following codebase: param name=codebase value=lib / Yesterday, I decided to update to wicket-1.2.6, and then, while testing this webPage again, I found ClassNotFoundException during applet's loading. So, after a little time doing try-and-error, I noticed that changing the codebase to the following, then it worked fine: param name=codebase value=../lib / I am using the lightweight jetty-server with the configuration inherited from wicket-examples. Nothing has changed during this development time, then, only the classpath in my Eclipse project, were I just changed to wicket-1.2.6. Any idea why is this happening?

[Wicket-user] BookmarkablePageLink converts String parameters to String[]? (Wicket 1.2.6)
Dear Sirs,
I updated to Wicket 1.2.6 and I have found the following behavior when
using BookmarkablePageLink (which was not happening before in Wicket
1.2.5). The code example is:
private class Link1 extends BookmarkablePageLink {
private static final long serialVersionUID = 1L;
public Link1(String linkId, String labelId, String labelValue,
PageParameters params) {
super(linkId, Page1.class, params);
this.add(new Label(labelId, labelValue));
}
}
When clicking on this link the error on Page1 (target page that
recovers params) is:
Caused by: java.lang.ClassCastException
After debugging it, I found that the page parameters (Strings added to
params) were converted to String[1], id est, all arrays, when
creating the BookmarkablePageLink. So it seems that there inside
happens this String2String[] transformation.
To jump over this issue, for the moment, I had to switch to standard
Link class, avoiding the use of BookmarkablePageLink.
What's the solution to this?
Thanks ;)

[Wicket-user] webPages variableFlow, backButton, theSmartAndCorrectWay?
Hi, Sirs, I have the following webPages variableFlow: Flow1: Page1 Page2 Page3 Page4 Page5 Page6 Flow2: Page1 Page3 Page4 Page6 As expressed in this flows, sometimes, depending on internal conditions, Page1 flows directly to Page3, jumping over Page2, and so it happens with Page4 to Page6, avoiding Page5. Then I have to return back using a button on each page, let's call it, back-button ;) As I need to keep state on all pages, when going back from PageN, I have to retrieve PageN-1, from inside a List (custom object) that I use to save flow history. But I guess there might be a much better and smart way to do this in Wicket. I haven't seen good examples of it, other than saving in PageN a reference to PageN-1, and then flowing using this internal references. So, is there any better way to threat with page history (back-button) and conserving state?
