Hi Holger, Scott and Bob,
Thank you for the quick reply.
First of all, I managed to go around the limitation by using some java
script called by the page load where I have the example of the code
below.
<html>
<body onload="createSession()">
<ui:createLink arg:applicationName="{=
PortalPlatform_spin:applicationName() }"
arg:id="PortalPlatform.sms:CreateSessionUser" arg:userName="{= ?
UserName }" ui:servlet="sparqlmotion">
<script>function createSession() {
window.location.href = '{=
?link }';
};</script>
</ui:createLink>
</body>
</html>
Holger,
Since you want some opinion, I agree with you that there are use cases
for both of your examples and if technically there is no implications
with having both, I would implement both.
My current use cases fits to your first example, where my SM end up
calling pages that are going to be built dynamically based on returned
parameters and/or Triples. I do not really know how to use the
snippets yet, but I am still in process of building the components
pages and I am sure I am going to need.
I also can't see the impact or the benefits of making the SM modules
ui:Elements as well. Can you elaborate on this? It may help me in
something else.
I am going to explain a bit of what I am trying to do, and you can
even point me to another direction if what I am doing is not correct.
Now, I am designing a portal application that is all based in SWP,
using HTML5 and Javascript. Really looking forward to use SVG when
inline becomes available.
The reason I am using SWP is because my entire logic is dynamically
captured in my executable models and I really need to have access to
resources like SPIN Functions, Templates, Magic Variables and SM to
run inferences because the entire sequence of pages, the content of
pages and events are going to be dynamically created using SPARQL
Queries { } based in state changes. I am also not an experienced Java
programmer to build an application using APIs, so I am keen t wait for
its full development.
This application has some similarities of what TQ have developed in
Flex for ensemble, where I defined HTML components like Forms,
Fields, Buttons, Menus, Events, Session, LoginForm etc . The meta-data
views instances are then stored in each separated executable models by
domain that import the components in the .ui model.
Here is my first scenario
I have a SWP page that is called pt:InboundEvent, that has a parameter
called pt:sessionGraphID.
A particular instance view of the page pt:InboundEvent is the
pt:login request with ui:name=login.
This login request does not have a pt:sessionGraphId as parameter,
because a session still needs to be created.
In this case, when the pt:sessionGraphId is not bound, my page
ui:prototype will call the script that creates a sessiongraph using
the user and timestamp information that imports the portal.ui and the
portalInstance.ui .
My script then call back the page, not the view, but in this case
passing the sessionGraphId as parameter and the sequence flows...
Second Scenario
A particular pt:InboundEvent is trying to perform updates, so I need
to validate if there is no constraints triggered with such update.
In this case the pt:inboundEvent call a page pt:makesUpdate that
performs the updates in the session Graph.
This page then call a script that will perform the update in a
dynamically defined model by passing the sessionGraphID as parameter.
This script is going to import the sessionGraph to find out the
relevant models are required for such update based on parameters
importing these required models dynamically to infer constraints.
In case there is no constraints the script will update the relevant
model and call a pt:OutboundEvent page that will just communicate a
successful update passing the new State moving dynamically to the next
page or will show the constraints stopping the update.
I already see a great benefits by having the ability to build pages
and also the sequence of events dynamically by using SM call that can
import and infer only the required models and triples, instead of
running inference in the entire application graph, what I already
verified would have performance issues.
I hope this helps, I am still in process of finding other cases that I
am going to share with you as soon as I have it. I am happy to talk
about my plans with SWP because I am keen in improving it.
Cheers,
Guil
