Re: [Wicket-user] getVariation and extended panels
Ok I'll try...
I was experimenting with the following with 2 panels... bascially
ChildPanel.getVariation() will override the SuperPanel.getVariation() so I
cannot have say a Blue SuperPanel and a Red ChildPanel... which would
then make it possible to have flexible combination of layouts by extending
the panels...
I am not sure if this is the right approach, so would like some advice.
right now I have move to just sticking to 1 variation to 1 hierachy
thanks
Joshua

Re: [Wicket-user] getVariation()
This is because the commomInit() method that is called in the constructor of WebPagealready also gets the markup to test for the body tag .But the strange thing is that this markup is not kept on to. So when rendered it should ask it again
and then the variation is encountered. I dont know why that doesn't happen.The problem still is that then the body thing is wrong (if suddenly the markup is swapped...)johan

Re: [Wicket-user] getVariation()
Yuck. As a dirty workaround you could create a custom request cycle
that overrides
onBeginRequest() {
style = getRequest().getParameter(style);
}
and then:
getVariation() {
return MyRequestCycle.get().getStyle();
}
Haven't tested it, but that should work.

wrote:Thanks Eelco, this workaround works... but
onBeginRequest() {getRequest().getParameter(style);
}doesn't work if the page is mounted. Unfortunately, every page of my webapp is mounted so that I can take advantage of the nice urls. Is there any more workaround to make getVariation() return a value from a page parameter?

Yuck. As a dirty workaround you could create a custom request cyclethat overridesonBeginRequest() {style = getRequest().getParameter(style);}and then:getVariation() {
return MyRequestCycle.get().getStyle();}Haven't tested it, but that should work.EelcoOn 11/2/06, Johan Compagner

This is because the commomInit() method that is called in the constructor of WebPage already also gets the markup to test for the body tag . But the strange thing is that this markup is not kept on to. So when
rendered it should ask it again and then the variation is encountered. I dont know why that doesn't happen. The problem still is that then the body thing is wrong (if suddenly the markup is swapped...)

How about this one?
public class MyPage extends WebPage { String variant; public MyPage(PageParameters p) { variant = p.getString(var);
System.out.println
(constructor called. The variant is now + variant); } public String getVariation() { System.out.println(getVariation() called! The value returned is +
variant); return variant; } } When I request the page (three times), It prints:
getVariation() called! The value returned is null constructor called. The variant is now earth getVariation() called! The value returned is null constructor called. The variant is now earth
getVariation() called! The value returned is null constructor called. The variant is now earth On 02/11/06, Eelco Hillenius

getVariation() always return null as if 'variant' never get set in theconstructor.

Re: [Wicket-user] getVariation()
Check that that constructor is actually called, and check that the var
parameter returns not null. If that is the case, your code should
work.
