Re: problem with IResourceListener
The strange thing is that only when the browser is just opened we see this behavior. It is not deterministic and sometimes everything is ok from start. Anyway, after a browser refresh, everything is ok. Also if we keep the browser open, and new tabs with the iframes are opened, these are also ok. So this problem seems to be related to iframe cache and some relation with flash. We do not have any hard clue yet. The only work-around we found was to do an auto-refresh for the page that contains iframes at first load, using javascript. Although the url generated like 0-IResourceListener-widget-renderer-chart we saw that for IE is always the same starting with 0, and the iframes are showing the wright content. In Firefox this number gets incremented. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/problem-with-IResourceListener-tp4652109p4652181.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: problem with IResourceListener
I analyzed these lines (two iframes = two sessions): requestUrl = widget?0-IResourceListener-widget-renderer-chartid=32836b83-27c5-43f7-a166-8ba38407d7dd objectHashCode = 12027390 requestUrl = widget?0-IResourceListener-widget-renderer-chartid=fb7e5efe-77c9-4494-9f99-9a577fef1687 objectHashCode = 12027390 The both request urls are the same without id parameter: widget?0-IResourceListener-widget-renderer-chart. My impression is that wicket doesn't have enough information to make a distinction between listener instances and it returns one of instances. Is my assumption correct?

Re: problem with IResourceListener
Hi, You make requests to the same page instance with the same components inside it. I.e. 0-IResourceListener-widget-renderer-chart always uses the same instance of 'chart' component.

Re: problem with IResourceListener
Thanks Martin I understand this. But why urlFor(IResourceListener.INTERFACE, null); returns 0-IResourceListener-widget-renderer-chart in both situations (two iframes in the same html file). The page version remains the same for both calls. It's ok this behavior? The problem appears only when I open for the first time the page with iframes. After a refresh from browser (Firefox, Chrome) everything is ok.

problem with IResourceListener
Hi
I want to make a open flash chart visible for an external web application
using a iframe. For this, I create a ChartWebPage and mount this page to
/chart.
In a few words, my problem is that the json data (string) returned by
OpenFlashChart (implements IResourceListener) are identical for both iframe
calls. Seems that wicket (1.5) returns same OpenFlashChart instance (see
hashCode from the console messages attached at end of the message) for both
iframe calls.
In other solution with json data served by a ChartDataResourceReference
mount on a /chart-data everything it's ok but are many code lines that
requires a change and I have a aggressive deadline.
My code:
public class ChartWebPage extends WebPage {
public ChartWebPage(PageParameters pageParameters) {
// for debug (see console)
System.out.println(ChartWebPage.ChartWebPage());
System.out.println(RequestCycle.get().getRequest().getUrl());
String chartId = pageParameters.get(id).toString();
String chartData = chartService.getJson(chartId);
add(new OpenFlashChart(chart, Model.of(chartData)));
}
...
}
public class OpenFlashChart extends GenericPanelString implements
IResourceListener {
public OpenFlashChart(String id, IModelString jsonModel) {
super(id, jsonModel);
}
@Override
public void onResourceRequested() {
// for debug (see console)
System.out.println(OpenFlashChart.onResourceRequested());
System.out.println(requestUrl = +
RequestCycle.get().getRequest().getUrl());
System.out.println(... + this.hashCode());
IResource jsonResource = createJsonResource();
IRequestHandler requestHandler = new
ResourceRequestHandler(jsonResource,
null);
requestHandler.respond(getRequestCycle());
}
private IResource createJsonResource() {
// for debug (see console)
System.out.println(OpenFlashChart.createJsonResource());
String jsonData = getModelObject();
System.out.println(jsonData = + jsonData);
IResource jsonResource = new ByteArrayResource(text/plain,
jsonData.getBytes()) {
@Override
protected void setResponseHeaders(ResourceResponse
data, Attributes
attributes) {
data.disableCaching();
super.setResponseHeaders(data, attributes);
}
};
return jsonResource;
}
}
In body section of my test.html file:
iframe id=1
src=http://localhost:8081/nextserver/app/chart?id=32836b83-27c5-43f7-a166-8ba38407d7dd;/iframe
iframe id=2
src=http://localhost:8081/nextserver/app/chart?id=fb7e5efe-77c9-4494-9f99-9a577fef1687;/iframe
In application console:
ChartWebPage.ChartWebPage()
chart?id=32836b83-27c5-43f7-a166-8ba38407d7dd
ChartWebPage.ChartWebPage()
chart?id=fb7e5efe-77c9-4494-9f99-9a577fef1687
OpenFlashChart.onResourceRequested()
requestUrl =
chart?0-IResourceListener-widget-renderer-chartid=32836b83-27c5-43f7-a166-8ba38407d7dd
... 12027390
OpenFlashChart.createJsonResource()
jsonData = {y_axis:{min:4.3441,colour:00,grid-colour:33,
...}
OpenFlashChart.onResourceRequested()
requestUrl =
chart?0-IResourceListener-widget-renderer-chartid=fb7e5efe-77c9-4494-9f99-9a577fef1687
... 12027390
OpenFlashChart.createJsonResource()
jsonData = {y_axis:{min:4.3441,colour:00,grid-colour:33,
...}

Decebal

Re: problem with IResourceListener
Additional information: if I put multiple OpenFlashChats in a (Dashboard)Panel everything is ok. The problem appears if I use iframes.
