Summary

0045775: PrintController.java, increase post() visibility

Description

Use case: I want to extend the printing process to:
1) Run some validations before printing a record
2) Run some business logic just after printing a record

To achieve that I need to develop a custom class that extends from PrintController and override doPost() to implement my logic and then call the super.doPost().

The problem is that the doPost() runs
final VariablesSecureApp vars = new VariablesSecureApp(request);
at the beginning of the method, which makes the vars.command to be reset to "DEFAULT".

This crashes the "send by email" feature (which expects a vars.command="EMAIL").

To workaround this I could easily override the post() method, which doesn't recalculate the vars variable, and which is called by the doPost().

The problem is that post() has package visibility, so I can't override it outside its package.

Steps To Reproduce

Create a class that extends PrintController in an external module.
Try to override post(). It's not visible outside the package.

Proposed Solution

Change PrintController.post() visibility to public or protected.

In the future, we should add some hooks to the printing process to allow easy extensibility.

One use-case is to handle vars and modification to vars in this method differently. Those vars are then passed to doPost method. --- M src/org/openbravo/erpCommon/utility/reporting/printing/PrintController.java ---
