LDM reloaded several times

[Sebastien <se...@gmail.com>]

Hi all,

Following a recent discussion about LDM being reloaded several times [1],
I've prepared a quickstart [2].

My concern was the following: I was thinking that a LDM relying on another
LDM, and reused on several components may have been reloaded several times
(because of the component's #reload which could have been called to early).

It seems to not be the case. Good news!

Then, I realized that I was using the LDM as a component model *and* in an
AjaxBehavior [3]. Of course, the AjaxBehavior initiate a new request,
causing the LDM to be reloaded.

I do not expect a solution here, it's just a wrong usage on my side. But as
I started the discussion, I wanted to loop the loop! :)

Thanks & best regards,
Sebastien.

Hi Ernesto,

(sorry for the delay in my reply)

No, I don't think so (if I understood your question correctly). The ajax
request is called from the page once loaded, i.e. really after the page's
request cycle.
I can trick by passing a non-detachable-chaining-model to page components
and let the behavior detach the model at the end of its request [1]... Not
very nice but it works :)

Sebastien.

@Sebastian,

Would a model that only detaches itself if there is no request target
scheduled after current work for your use case?

Hi Sebastien,

Seems to work as designed! :-)
The Ajax request is in a second request cycle so it loads it again.
I guess you can create some kind of ConversationModel (CDI conversations)
but this is totally different model impl.
