<div class="jive-rendered-content"><p>To illustrate the problem, I attached a simple dummy test. After deploying  it (execute the deploy class) and istantiating (using the class CreateInstance) a process with a test variable (testvar) that should be stored in a long text field  is created. the acutal code looks as follows:</p><p style="min-height: 8pt;
