Open document handling (DocuView) for other datasource/table than caller

Sometimes there's requirement to open document handling from one form to shows the documents for other datasource/table.


Eg. From Purchase order form, open the document handling of the vendor (VendTable) instead of for the purchase order (PurchTable).


It can be achieved with the following 4 steps:
  1. Add the related table as datasource in the form
  2. Add a boolean global variable to 'ClassDeclaration'
  3. Overwrite the method 'docCursor'
  4. Add a button and overwrite the 'clicked' method

1. Add the related table as datasource in the form




2. Add a boolean global variable to 'ClassDeclaration'
class FormRun extends ObjectRun
{
    boolean      vendDoc;
}


3. Overwrite the method 'docCursor'
public Common docCursor()
{
    Common docCursor;
    ;


    docCursor = super();


    if(vendDoc)
        docCursor = vendTable;
    
    return docCursor;
}


4. Add a button and overwrite the 'clicked' method
void clicked()
{
    super();


    vendDoc = true;


    if (!infolog.docu().isDocuViewSet())
        infolog.docu().note(element);
    else
        infolog.docu().setActive();


    vendDoc = false;
}
