Lets Let's say we want to change workflow variables directly inside a system tool activity without creating having to create a complex beanshell script. This The Process Tool Plugin assigns a simple expression into to a workflow variable. The expression is evaluated using a beanshell interpreter, and the resulting value is converted into a string. The workflow variable is then assigned to this that string value.
All workflow variables are directly accessible inside the expression, but note that all joget workflow Joget Workflow variables are of String the string type.
Usage
...
Scenario:
- set Set a workflow variable to a constant value: use . Use AssignVariablePlugin as a tool, . Use the parameters are : workflow variable name : A, expression expression : 0.
- to To increment a workflow variable value : , use AssignVariablePlugin as a tool, . Use the parameters are : workflow variable name : A, expression : Integer.parseInt(A) + 1.to
- To decrement a workflow variable value : use AssignVariablePlugin as a tool, . Use the parameters are : workflow variable name : A, expression : Integer.parseInt(A) - 1.
Steps
...
in Creating a Plugin:
Create an empty project folder. Inside this folder, create subdirectory src\main\java\myplugin.
