Karl M. Davis commented on WICKET-631:
--------------------------------------
I just wanted to confirm this bug. I sent out a long email to the listserv a
minute ago that covers an easy way to hack around it, but I'll repeat the
relevant portions here for the record:
In my DynamicWebResource class, I added a "cachedParams" ThreadLocal and cache
the parameter ValueMap during setHeaders(WebResponse) in it, because the
parameters get wiped out before getResourceState() is called. Here's the code
for that in case anyone needs it:
public class SomeResource extends DynamicWebResource
{
private static ThreadLocal<ValueMap> cachedParams;
...
/**
* @see
org.apache.wicket.markup.html.DynamicWebResource#setHeaders(org.apache.wicket.protocol.http.WebResponse)
*/
@Override
protected void setHeaders(WebResponse response)
{
super.setHeaders(response);
cachedParams.set(getParameters());
}
...
/**
* @see
org.apache.wicket.markup.html.DynamicWebResource#getResourceState()
*/
@Override
protected ResourceState getResourceState()
{
ValueMap params = cachedParams.get();
...
}
}
> Resource.getParameters() empty when resource is mounted

>
> After migrating my application from 1.2.6 to 1.3.0-incubating-SNAPSHOT
