Getting exception below building rules that build in 3.0.4.
Looking at FunctionBuilder we have at line 106. The code in red looks
suspicious? Seems it should be mapping "mapping" against the name.
But that is not what is the cause of the exception apparently put is not
supported?
String name = pkg.getName() + "." + ucFirst(
functionDescr.getName() );
LineMappings mapping = new LineMappings( name );
mapping.setStartLine( functionDescr.getLine() );
mapping.setOffset( functionDescr.getOffset() );
lineMappings.put( name, lineMappings );

yep - looks like a bug to me on a quick look - do you want to attach a
simple test to a JIRA?

New subject: 'if' in guided editor
I noticed that 'if' is used in the guided editor instead of 'when',
whats the reason for this? As currently I explain the use of 'when'
because it indicates its not procedular, where as 'if' is considered
part of a procedural logic flow. Will this confuse that explanation?

New subject: 'if' in guided editor
no, it was just to be different. It can be anything. It can be
"wassup" or something ;)
Not sure if that explanation has any real meaning, I mean it makes a point,
but "when" actually implies to me that it is slightly temporal (ie
"when"
means it will happen, at some point in time, where as "if" means it may or
may not happen - neither of which are procedural/imperative).
I think its ok to say IF, as people still say "if/then" for production
rules, its not really confusing - perhaps we need another way to explain
imperative versus declarative.

New subject: 'if' in guided editor
Is using 'if' and 'when' confusing? should be not standardise over it?
I think "when" is used as you say "when this then that" not "when
this
maybe this or maybe that else that", where as if/else is a common usage
- so helps emphasis that rules are more atomic.
With Edson's work is this not all localisable now anyway? If so, need to
make sure that the guided editors obey his keyword localisation work.

Mark,
Yes, from a DSL Compiler perspective, keywords are customizable. But
from tools perspective, they need to add support to that. Also, I think
Michael is generating DRL directly from the editor, aren't you Mic? So
this is only a tool thing...

yes its only a tool thing, exactly. purely for the UI, so it can say
whatever we want.
"When" is OK with me - but I am not sure if the argument of if == imperative
vs. when == declarative is the best - it may make sense to new users, but it
does sound a little contrived to me (I always cringed at the explanation).
I guess pragmatically speaking: Java, C, C#, C++, perl, python, ruby all
have "if" but not "when" - given they are the most common imperative
languages, using "when" probably makes good sense as a differentiation point
now I think of it.
The Rule Modeller localisation mainly comes down to i18n style .properties
files anyway - whereas DSL is user customisable - but we could make it use a
DSL file eventually.
basically, platofrm i18n will eventually be done by engineering services
here, but it will really be based on user demand, whereas DSL allows users
to do what they want when they want.

It's not so much imperative/declarative but that if indictes its part of
a sequence of logic, when is more atomic - but it is contrived :)

well, its good to take a position on something, so lets have an opinion, and
make it "when" cause "if" is for sequential logic in imperative
languages !
So "When" it is !
