[scxml] release or current svn code not backguard compatible
Hi guys,
I have been running now for 6 months my project
without any update from svn. I decided to go for the
release today since I wanted to debug something.
Something weird is happenning with jexl returning
always "false" for any evaluation.
With an example I have in my scxml:
<n:transition event="SendPinReq"
cond="clientProfile.getCurrentApplication().getAppId()
eq '2'" target="aIDLE2UPSENDb"/>
This is used by:
JexlEvaluator#evalCond(final Context ctx, final String
expr)
where
expr="clientProfile.getCurrentApplication().getAppId()
eq '2'"
But that code does not get really evaluated and
JexlEvaluator#evalCond(Context, String) returns false.
I did not give it a try but can it be the namespace
control that I read was recently added? I use <n:...
for all of my statements since I am using a custom
schema based on the one w3c posted ... something like:
<n:scxml version="1.0" initialstate="IDLE"
xmlns:n="http://www.w3.org/2005/07/scxml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.w3.org/2005/07/scxml
http://pathtoserverhere/scxml.xsd">
Any help greatly appreciated.
Thanks,
-Nestor

You would be inserting those in the root context? Thats available to
all states. Sorry, I'm not sure what snippet you want (below). What
will be faster is an example that I can work with (sort of a "before"
so we can have an "after"). Thanks.

That could be the issue, I am inserting in the context
the objects I want to expose to scxml and so if now
the context depends on the state I must update the
state context with my unique per session one.
You will understand that for a WEB Application (I am
using SCXML as Controller) I need my session to be
unique and I take care of areas of course to keep a
namespace aware architecture.
Now the question is could you paste here a snippet of
code that will make the trick of exporting my unique
context to each state the application reaches?
Thanks,
-Nestor

Can you post a small (but complete) document (or better, JUnit test
case) that illustrates the issue you're seeing? That will definitely
help. The namespace (below) looks OK.
The other change made while in sandbox was that each state has its own
context (though it can view variables in the parent contexts, like
blocks in Java) -- previously there was a flat context for the entire
document.
Bearing that in mind, are the <var> declarations visible to the
<transition>? If not, you'll need to move them up along the ancestor
heirarchy to a visible location.
