In Joget, a form field and a workflow variable, even if named similarly (e.g., both called "status"), are distinct entities. A form field is specific to a form and is used to capture user input, while a workflow variable is a broader process-level variable that can influence and guide the workflow's progression and routes taken. So in this case, the 'status' variable are also stored in different database tables.
Key Concepts
Hash Variables
Hash Variable is a special hash-escaped keyword that can be used in (but NOT limited to)...–Form Builder–List Builder–UI Builder–Supported plugin configuration properties–Activity name in Process Builder–External Form URL when mapping an activity to an external form...to return the value of useful runtime variables from the (App) Variables.
In Joget, a Hash Variable is a specialized, hash-escaped keyword that has a wide range of applications across different components of the platform. It can be used in the Form Builder, List Builder, and UI Builder to dynamically retrieve and display the values of runtime variables. Beyond these builders, Hash Variables are also utilized in configuring properties for supported plugins, naming activities within the Process Builder, and specifying external form URLs when mapping activities to external forms. This versatile functionality allows Hash Variables to effectively pull and display relevant runtime information from the application's variables, enhancing the dynamic interaction and responsiveness of the application to real-time data changes.
Update Mechanisms
Form Data Update Tool: This plugin is used to update values directly in the database. The changes made using this tool affect the data stored in form fields. It is an efficient way to ensure that the data entered or modified in form fields is accurately reflected in the database.
Workflow Variable Update Tool: Available at the marketplace,
...
the Workflow Variable Update Tool updates the value of workflow variables. It's used when there's a need to modify the values of variables that control or influence the workflow process.
Besides this tool, BeanShell scripting can also be used to update workflow variables. BeanShell is a lightweight scripting language that offers a flexible way to write scripts for various purposes, including updating workflow variables. While BeanShell scripting provides a powerful and flexible way to manage workflow variables, the Workflow Variable Update Tool is often preferred for its user-friendliness and ease of use, especially for users who might not be comfortable with scripting.
