Form Entry Use Cases

Complete Form Entry Use Case

• Complete Login use case.

• Select Form Entry use case.

• Enter patient name in search box.

  • System will retrieve all patients matching the entered search term.

• Select appropriate form.

  • A request for /openmrs/formDownloadServlet is sent to server. FormDownloadServlet handles request and generates an XML response that contains the form schema (xsd) along with information that will tell the browser to open InfoPath to display the form. Unless previously instructed, the browser will prompt you to Open or Save the document. The XML below helps the browser figure out what it needs to do with the response.

<?xml version="1.0"?>
<?mso-infoPathSolution name="Demo Form" href="http://localhost:8080/openmrs/formentry/forms/DemoForm.xsn" solutionVersion="" productVersion="11.0.6357" PIVersion="1.0.0.0" ?>
<?mso-application progid="InfoPath.Document"?>

• Select the "Open with InfoPath" option.

  • InfoPath will look for the XSN form at http://localhost:8080/openmrs/formentry/forms/DemoForm.xsn and attempt to open it. If successful, the form will be displayed. Otherwise, InfoPath will display an error message. See InfoPath_Notes#Troubleshooting for more information on specific errors.

• Enter data into the form. This may require stepping through several pages of a form.

• Select Submit button on last page of form.

• InfoPath POSTs a request containing your form data to the FormUploadServlet.

• FormUploadServlet creates a FormEntryQueue record, sets its XML data field with XML form data from the post, and stores the FormEntryQueue in the database.

Process Form Entry Queue Use Case

• Scheduler spawns a ProcessFormEntryQueueTask every X seconds.

• ProcessFormEntryQueueTask delegates to FormEntryQueueProcessor.

• FormEntryQueueProcessor iterates through the FormEntryQueue.

• FormEntryQueueProcessor transforms XML data in FormEntryQueue using an XSLT associated with the given form.

• FormEntryQueueProcessor creates and stores the HL7InQueue record.

Process HL7 Queue Use Case

• Scheduler spawns a ProcessHL7InQueueTask every X seconds.

• ProcessHL7InQueueTask calls HL7InQueueProcessor.

• HL7InQueueProcessor iterates through the HL7InQueue

• HL7InQueueProcessor processes all HL7InQueue records.

• HL7InQueueProcessor creates an Encounter and Observations based on the HL7 messages in the queue.

Troubleshooting

If InfoPath is not behaving as expected (changes aren't being reflected, etc), the problem can often be solved by clearing the cache. You can run the following on the Windows command line or create a batch file.

"C:\Program Files\Microsoft Office\OFFICE11\infopath.exe" /cache ClearAll
