Re: problem with ShellScript component

Hi Andreas,

I found the problem.

The reason why this component does not work is because it does rename
its log using the attribute sfLog with the following definition:

sfLog LAZY THIS;

This causes sfResolve to spin in an infinite loop because sfResolve
tries also to initialize the log when in trace mode. 

I know now how to fix the problem and I will check in a fixed version in
CVS on Monday. In the mean time the simplest fix for it is to modify the
file:
org/smartfrog/services/shellscript/components.sf, that it is contained
in smarfrog.jar, by commenting the attribute "sfLog LAZY THIS;" in the
components: Process and Shell.

I apologize for the inconvenience that this caused you and thank you for
sending a very accurate report for the bug. 

I will also add this bug to our bug tracking system:

http://jira.smartfrog.org/

Regards,

Julio

PS: the domain name smartfrog.org is being migrated to a different set
of domain name servers and there can be some problems for the next 48
hrs.
