Antonio Gallardo commented on COCOON-1931:
------------------------------------------

Would you test the 2.1.10 branch on subversion. I think it was fixed just f=
ew days ago. I tried to reproduce the issue using the calculator flow sampl=
e:

http://cocoon.zones.apache.org/demos/21branch/samples/flow/

Here is what I did:

1. When I removed the file, I got:=20

java.io.FileNotFoundException: /home/agallardo/svn/cocoon-2.1/build/webapp/=
samples/flow/jxcalc/calc.js (No such file or directory)

2. When I remove a closing ")" for a funtion call I got:

Missing ")"

etc.

Would you try the newest version and try to provide an NPE? If you are not =
able, please let us know to close this issue. Many thanks in advance.

>             Project: Cocoon
>          Issue Type: Improvement
>          Components: - Flowscript
>    Affects Versions: 2.1.8, 2.1.9, 2.2-dev (Current SVN), 2.1.10-dev (cur=
rent SVN)
>            Reporter: Georg H=C3=BCttenegger

>         Attachments: FOM_JavaScriptInterpreter.java.MoreErrorInfoPatch

> When a flowscript defined in the sitemap cannot be loaded a NullPointerEx=
ception is thrown without telling the developer the real cause of the issue=
.
> The same is true for certain Javascript coding errors (at least missing c=
losing bracket of a for loop).
> The provided patch throws a CascadingRuntimeException with the name of th=
e flowscript instead of just a simple NullPointerException. In that way the=
 developer is lead directly to the cause of the problem instead of wonderin=
g what the real issue might be.
