OpenEMM Technical Support Forum

Hi all,

I installed OpenEMM 2013 on a Gentoo 64 bits Linux machine. I compiled everything from scratch, following the installation pdf. Everything is working fine except scriptaction.

It looks like it is ignoring the #set ($scriptResult="1"). I setup a form with "$scriptResult true" for true and ""$scriptResult false" for false. Made an action just with #set ($scriptResult="1") and added it as a start action for the form. Setting $scriptResult to any value throw the form in the error state, even for 1.
After reading again the docs, searching in forum, etc, I deleted everything and started again from scratch, with the same result.
Next, keeping the database, I installed the old version OpenEMM 2011 which worked as expected out of the box!

Anyone any idea if it is a glitch of my 64 bit operating system or a bug? Running tomcat-6.0.36:6 and java sun jdk 1.6.0_31-b04.


Thanks in advance,
Vladi

Hm, script actions are based on Velocity (JAR file "velocity-1.5.jar"), but we are not aware of 64 bit problems, in fact we use the software on 64 bit servers ourselves. Are you absolutely sure you have no typo in your code and did you check the logs for any Velocity related output?

Hi,
below the logs for velocity:
OpenEMM 2011 with scriptaction working:

In red is what I found as a significative difference.

Hi again,

I looked in 2011 and 2013 versions of ExecuteScript.class and I took out the extra check of parameter error, recompiled and it works now.
However I think the check was there with a purpose ...

So the line 112
if(params.get("scriptResult").equals("1") && params.get("errors") == null) {
becomes:
if(params.get("scriptResult").equals("1")){

Now I did not know what kind of variable is "error", but I suppose is an array of strings, and I think that it is not null but empty.
Comparing it with "{}", works ( I do not know enough Java to find a more elegant test).
if(params.get("scriptResult").equals("1") && params.get("errors") == "{}") {

I also think that in the end the velocity logs contains only harmless warnings unrelated to this issue.

Should I leave the if clause like original or not?

Part 1 of my answer:

OpenEMM 2011 used velocity-1.4.jar, OpenEMM 2011 uses velocity-1.5.jar - maybe the JAR update is the reason for the changed behaviour?

That Velocity does not find default library "VM_global_library.vm" is just for information, but not a problem. We get this message, too, and the file is not needed. See here for more info:

http://stackoverflow.com/questions/5313 ... library-vm

Part 2 of my answer:

We looked into this issue: The code line has changed from OpenEMM 2011 to 2013 when we introduced Velocity logging and your change changed this line back to the 2011 version. But it looks like the logging was not implemented correctly leading to parameter "errors" beeing false all the time. So, your change is correct for now, but we may have to provide a bugfix to fix the logging. Thanks for diving into the source code and for pointing out this problem!

OK, this would be the bugfix: Could you please try if this line works for you?

I updated ExecuteScript.class with the one in your bugfixes (file modified 2013-03-07) but the problem still exists:
An action with simply: produce Error Form

I tried the bugfix myself. Before the fix I could reproduce your problem, after applying the fix I could not. Did you restart OpenEMM after replacing the class file?

Sorry, it was my fault, your bugfix was sufficient to solve the problem.
Thanks (even if I'm a little late )

Fine, thanks for your feedback!
