- 26. Communicate from Forms to APEX Use web.show_document( URL, target )
- 27. Attach a common library to your Form
- 28. Create procedure runJavascriptRequirement :When I move through a list of Products (Oracle Form), I want to see who bought it and where the customer is located.PROCEDURE runJavascript( pScript varchar2) ISBEGINweb.show_document('javascript:'||pScript, '_self'); END;web.show_document( โjavascript:showOnMap()โ, โ_selfโ);
- 29. Communicate from Forms to APEX Call procedure from WHEN-NEW-RECORD-INSTANCE
- 30. Create procedure TriggerApexPROCEDURE TriggerApex( pTrigger varchar2 ) ISBEGIN if name_in('system.current_form') = 'PRODUCTS' then if pTrigger = 'WHEN-NEW-RECORD-INSTANCE' then -- Requery APEX Reports region with parameter on Page 9 -- & Show the data on the Map runJavascript('refreshReport('||name_in('PRODUCTS.PRODUCT_ID')|| ', ''P9_PRODUCT_ID'');showOnMap();'); end if; end if;END;TriggerApex('WHEN-NEW-RECORD-INSTANCE');

- 35. raiseEvent procedure โ extend the Forms runtime
- 36. CommunicatorBean โ receive external events
- 37. Add PJC to your FormCommunicate from APEX to Forms Define column link as : javascript:queryCustomer(#ID#);
- 38. raiseEvent triggers (Beanโs) WHEN-CUSTOM-ITEM-EVENT
- 40. execEvent handles the request
- 41. Add code to TriggerApex procedure in library to refresh reportfunction queryCustomer( pCustId ){ //Setting Customer Id in Form and RequeryexecFormAction( 'execute_query', pCustId)}function execFormAction(pAction, pParam){ //Raising an event in Forms //Execute the Action (like 'execute query') $x('formsapplet').raiseEvent(pAction, pParam );}PROCEDURE execEvent ISBeanEventDetailsParamList;ParamType number := text_parameter; Event varchar2(1000); Payload varchar2(1000);beginBeanEventDetails :=get_parameter_list(name_in('system.custom_item_event_parameters'));get_parameter_attr(BeanEventDetails, 'Event', ParamType, Event);get_parameter_attr(BeanEventDetails, 'Payload', ParamType, Payload); if name_in('system.current_form') = 'CUSTOMERS' then if upper(event)='EXECUTE_QUERY' thenset_block_property('DEMO_CUSTOMERS' , DEFAULT_WHERE, 'WHERE CUSTOMER_ID = '||payload );execute_query; end if; end if;end;if pTrigger = 'POST-DATABASE-COMMITโthen -- Requery APEX Reports region with pValue, pField parametersrunJavascript('refreshReport('''', '''')');end if;

- 44. HTML mustbe 100% identical
- 45. Start up the sameFormevery time (landing)
- 46. Pass the โrealโ Form name to the landing form
- 47. Use WHEN-APPLET-ACTIVATED event to callthatForm
- 48. Details are in Wilfredโsdoc!! if upper(event) = 'WHEN-APPLET-ACTIVATEDโthen while true loop -- get the form nameset_custom_property('BLK_PJC.PJC', 1,'EvalExpression','$v("CALL_FORM_NAME")');formName := get_custom_property('BLK_PJC.PJC', 1, 'EvalResult');call_form(formName);appletActive := get_custom_property('BLK_PJC.PJC', 1, 'AppletActive'); if appletActive = 'FALSEโ then exit; end if; end loop;end if;
