Hi,
I got a javascript typed input parameter which contains a FreeMarker-String.
Is it possible to process the FreeMarker-content inside the javascript? I found this old link, but it looks like thats this approach does not work for 7.10 anymore. ( I just get a TypeError: null has no such function “createBindings” error.
Best Regards
Alex
@Alex.Ph please share your javascript code you are using. Also what is your env? THis is the standard tomcat distro?
Hey, we are using camunda 7.10 with Wildfly 14.
I just create a new user task with an input parameter of type javascript with following test-code:
var ScriptEngine= new JavaImporter(javax.script);
with (ScriptEngine) {
var manager = new ScriptEngineManager();
var engine = manager.getEngineByName(“freemarker”);var bindings = engine.createBindings();
“bla”;
};
Error: Unable to evaluate script:TypeError: null has no such function “createBindings” in
is freemarker installed as a dep?
https://docs.camunda.org/manual/7.10/user-guide/process-engine/templating/
Yes it is.
I can define a variable in user task A (test=ABC) and use it in task B ${test}. Or do these “magic” freemarker replacements have nothing to do with your provided link? 
Alex
your error seems to suggest that the var engine is returning null.
I would recommend you retry by using Groovy, and see if it returns a more robust error message.
Ok, I replaced the javascript code with groovy code:
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;manager = new ScriptEngineManager();
engine = manager.getEngineByName(“FreeMarker”);println "engine: "+engine
The engine is null. I also tried “FreeMarker”. (“javascript” works btw).
I listed all available script engines. It looks like that I am not able to use freemarker at task execution time…:

Run a script task with your script and see if works. Is it that you are running this as a inout mapping ?
I executed the script as script task and got the same results.
Before that I used an scrippted input parameter to execute the code.
Weird thing is, that I can use freeMarker scripts in user tasks, but the scriptEngine inside the script code does not find freemarker.
Do I have to enable “something” to be able to find freemarker in javascript or groovy scripts?
Can you download/pull the Camunda tomcat 7.10 docker image and test against that?
Mhh, Tomcat with camunda 7.10 knows freemarker … I have to check, how I can add freemarker to the scriptengine in wildfly

So you have followed these instructions ? https://docs.camunda.org/manual/7.10/user-guide/process-engine/templating/
No I didnt, because we are using the prepacked docker distribution.
But I checked the instruction and had a look into the folder and modules. Everything seems setup correctly out of the box, but the script doesnt list the freemarker engine.
I think will create a new thread in the process-engine forum, cause this issue has nothing to do with the modeler anymore.
Thnx for the help so far
