⇱ 🧩 Invoke BeanShell Hash Variables Dynamically in Joget - DEV Community

1. Why This Is Useful

When you need to call another BeanShell helper dynamically, hash invocation keeps your main script small and reusable.

This pattern builds a hash string at runtime, executes it with AppUtil.processHashVariable, and captures the output for reuse.

2. Where to Use in Joget

  • Workflow Tool scripts that need reusable helper logic.
  • Form/Post-processing scripts that call another BeanShell utility.
  • Notification-related scripts where output from another function is needed first.

3. Core Idea

  • Build the hash string with required parameters.
  • Execute it through AppUtil.processHashVariable(...).
  • Use returned value in logs, payloads, or downstream logic.

Example hash format used:

#beanshell.captureResponseNotification[process_id=YOUR_PROCESS_ID]#

public String getBranchName(String locale){
 String callHashToInsertResponse = 
 "#beanshell.getComplaintDetailsForEmail[c_code=" + "#variable.branch_code#" + "&locale="+ locale + "]#";

 // Evaluate hash
 String result = AppUtil.processHashVariable(callHashToInsertResponse, null, null, null);

 return result;
}
*/

String ProcessID = "testing the process id";

// build valid hash format
String callHashToInsertResponse = 
 "#beanshell.captureResponseNotification[process_id=" + ProcessID + "]#";

// Evaluate hash
String result = AppUtil.processHashVariable(callHashToInsertResponse, null, null, null);

LogUtil.info("Email Integration - API", "Evaluated Hash = " + result);

5. Quick Validation Checklist

  • Verify the target BeanShell function name is correct.
  • Confirm all required parameters are included in the hash.
  • Log output once to validate returned value.
  • Test with safe sample process IDs before production use.

6. Security and Publishing Note

  • Replace real process IDs, variable names, and function names with placeholders in public content.
  • Avoid exposing internal workflow naming conventions.

7. Final Note

This is a strong pattern for reusable Joget scripting: one script orchestrates, another script handles details, and hash invocation connects both.
