I found an example in the SWP manual that made me think about what
ui:tempGraph is doing. It seemed to me that I could just create a node in
the current graph and set/get values from it using ui:update and spl:object
without using tempGraph (not that I had gotten it to work anyway). So I
Hi Jack,
what you are looking for is some kind of global variable mechanism. The
SWP variable scoping mechanism doesn't have this built-in, and I have
not run into a use case for them yet, but I can see that this should be
easier. So I have added a couple of helper modules in the attached
Is these (both the INSERT and the SELECT something that would be embedded
inside my SWP forEach? Even if it is its going to be messy and ugly. Can I
take the ui:update block and the other code and put them into SPIN
functions or magic properties to unclutter the SWP? So far it isn't
working...
I tried several things, including embedding the INSERT into an SWP function
(setLocalVariable) and the SELECT into a normal SPIN function
(getLocalVariable). But they didn't work. I also tried it with the
spl:objectInGraph followed with a call to my SWP function but that didn't
work.
Then I
I'll try it, but my original question did state that I was trying to
remember a value between iterations through a foreach...
That said, I reread the SPINx documentation and it is unfortunate that the
name of the file in the example was the same as the namespace prefix when
it didn't have to
Does the root name of the javascript file have to be the same as the prefix
for the namespace of the SPIN file? That doesn't seem to work either.

I don't think SPINX would be helping you, even with a stand-alone file -
each invocation of such a SPIN function would get its own JavaScript
engine, and all intermediate values will be lost.
Your computation below looks like easily done in SPARQL. All you need to
do is remember the
and performs some calculation? I am trying to calculate a display position
for part of a graphic inside a ui:foreach. The position is based on the
position of the previous item in the iteration. It is easy enough to write
a js function that will maintain the variables and their values, and
ui:functionCall is only producing JavaScript source code that would be
executed client-side. If you want server-side execution of JavaScript
logic, you could use SPINx
