Hi @hassang,
Here are all related files:
config.txt (1.6 KB)
loadSimpleMDE.txt (103 Bytes)
sample-form.txt (379 Bytes)
I didn’t upload the simplemde.min.js, because its an official js file.
The locations of the files in the deployed webapp are:
config.js: /camunda/app/tasklist/scripts
loadSimpleMDE.js: /camunda/app/tasklist/scripts
simplemde.min.js: /camunda/app/tasklist/scripts
sample-form.html: located in the external process application and referenced as a startform for a bpmn process
So please have a look on the files, if something is wrong or missing 
Best regards
Marvin
PS: I had to convert them to txt, because it’s not allowed to upload html or js files.
Did you clean the history of the browser?
Yes, I cleared my whole history and the cache, but without any effects.
What is the exact error message now?
What is the browser you are using?
I am using Google Chrome
The only thing I can think about is your simplemde.min.js file…
Can you please make sure that your content is identical to the original one?
Recopy the content of it… please…
Hi @hassang,
It works 
In the end you post: How to use external libraries in embedded forms (Tasklist) suddently works, I’m not sure why it was not working before, maybe because I didn’t cleared the cache at this point of the conversation.
So thanks a lot for all your assistance 
Best regards
Marvin
