JSON Parsing Error when using german letters ä, ö, ü in process definition

b_schnarr — Sun, 12 Jan 2014 12:40:43 GMT

When I try to model a process using activity kickstart (table-driven editor), I get a JSON Parsing error every time I use the german letters ä, ö, ü. The error occurs when I try to deploy the process or when I try to edit the process. Even though there is a german translation for the activity explor

What exact error do you get?

Steps for reproducing:
1.) Model a simple process with the table driven editor (Kickstart)
2.) Use the letters ö, ä, ü in name or description fields
3.) Save the process
4.) Under Model action, try to delete or deploy the new process

When you klick on deploy, an error message will occur in the activity explorer: Warnung! Error while parsing JSON (look at the picture below)

This is the exception stack I'm getting:

Seems like an issue with the encoding of the created JSON by the table-editor. I'll take a look at this…

Is it foreseeable that this issue will also be fixed with 5.15?

What version are you using ?
I just tested the turkish characters with the latest version and it seems is working ok.
<code>
<process id="process1" name="2ff" isExecutable="true">
<startEvent id="processğüş" name="processğüş"/>
<endEvent id="sid-69D0AE78-DC50-4256-9053-5D4DA10A240C"/>
<sequenceFlow id="sid-1187749E-C481-4F7A-8516-7C694E6F120B" sourceRef="processğüş" targetRef="sid-69D0AE78-DC50-4256-9053-5D4DA10A240C"/>
</process>

Hi,

I am using 5.17.0 version. When i use eclipse plugin or web modeler to create process definition with special turkish characters, there is no problem to deploy process, however, when i use table editor, it causes

com.fasterxml.jackson.core.JsonParseException: Invalid UTF-8 middle byte 0xfc.

Actually, Table editor saves the model, however, at the deployment step, it throws above exception.

In my opinion, there is a problem while converting the WorkFlowDefinition object to byte array with utf-8 encoding, because firstly the program converts to byte array and stores this byte array to database and then when it gets this byte array from database and converts the WorkFlowDefinition object with utf-8, it throws above exception because this byte array is not utf-8 encoded.

Do you test turkish characters with table editor?

I hope, I will express myself correctly.

Thank you for your help

Hi mertagtas,
It's true I tested it with explorer (web editor) but didn't test in the table editor.
Since you already investigated this issue and you are so close to a solution, don't be shy just go ahead and create a PR for it

I'm sure there are community members will appreciate a fix for it.

Hi,

I downloaded the latest version (5.18.1-SNAPSHOT) source code from github repo and run the unit test of JsonConverterTest with turkish characters and there was no such exceptions. Then, I deployed war file to my local development tomcat server and table editor didn't throw exceptions. Actually, it seems the problem is already solved.

Thank you.
