Thank you Igor and Alex for your answers.
I managed to send the itemId parameter to WebRequestCycle, by modifying
the URL inside wicketAjaxGet, generated by AjaxLink.
The code looks like this:
c.add(new AbstractBehavior() {
@Override
public void onComponentTag(Component
component,
ComponentTag tag) {
inservAdvIdInAjaxLink(tag,
advertisementId);
}
/**
* Insert advId at the end of the url
inside wicketAjaxGet from tag
attribute onclick.
* @param tag ComponentTag
* @param advId advertisement id
*/
private void
inservAdvIdInAjaxLink(ComponentTag tag,
String advId) {
String onclickElement =
(String) tag.getAttributes().get("onclick");
String elementToModify =
"wicketAjaxGet('";
String subOnclickElement =
onclickElement.substring(onclickElement.indexOf(elementToModify) +
elementToModify.length());
String ajaxHref =
subOnclickElement.substring(0,
subOnclickElement.indexOf("'"));
onclickElement =
onclickElement.replace(ajaxHref, ajaxHref +
"&itemId=" + advId);
tag.put("href", ajaxHref +
"&itemId=" + advId);
tag.put("onclick",
onclickElement);
}
});
The 'onclick' attribute changed from:
wicketShow('id10--ajax-indicator');var
wcall=wicketAjaxGet('?wicket:interface=:2:10:::0:',function(){;wicketHide('id10--ajax-indicator');}.bind(this),function()
{ ;wicketHide('id10--ajax-indicator');}.bind(this), function() {return
Wicket.$('id10') != null;}.bind(this));return !wcall;
to:
wicketShow('id10--ajax-indicator');var
wcall=wicketAjaxGet('?wicket:interface=:2:10:::0:&itemId=xxx',function(){;wicketHide('id10--ajax-indicator');}.bind(this),function()
{ ;wicketHide('id10--ajax-indicator');}.bind(this), function() {return
Wicket.$('id10') != null;}.bind(this));return !wcall;
If someone have a more elegant solution, please post it.
