Possibility of mounting Wicket resource accessible only once
Hi,
Is it possible to mount a resource programmatically (Eg. On click of an
AjaxLink), and make it available only once ?
I looked into dynamic resources concept of having a mounted resource, which
uses URL attributes to decide which resource content to return from
getResource() method of it.
In my case, URL remains the same but what to return from getResource() is
decided based on the context when user clicks on an AjaxLink.
Any pointers how to implement it ?
Regards,
Rakesh.A

Questions...
1- What happens with mounted URLS not visited (stay in memory as far as I
can see)
2- What happens after server restarts (guessing they disappear)

Hi,
URLs I can add some code to make them unique, and unmounting from
#getResource() seems better place indeed.
Thank you for the inputs.

One issue could be that later you mount again another resource(reference)
on the same path and this is against your initial requirement. I also
thought about storing tokens in some persistent storage like Ernesto. But
you know your requirements better!
You can do the unmounting in ResourceReference#getResource() method too.
There you know for sure that this is the temporary resref that should be
unmounted.

Hi,
Having the token persisted into DB seems bit complex to solve this 'dynamic'
resource issue.
The way I've implemented it right now, is to have this resource reference
unmounted, from AbstractRequestCycleListener#onRequestHandlerExecuted()
method, where I've access to IRequestHandler and the resource reference
object it self (checking for ResourceReferenceRequestHandler)
Do you see any issues with this approach ?

Rakesh.A

Hi,
you can mount a resource like
"willdisapear/${token}"
you create a "table" tonkens... and add an element when users clicks. e.g.
"xxyyxxxooq". One user visit this url you delete token and URl is no
longer there.
