ConcatenateEForms: PerformFieldFlattening does not work.

SA-8285

Summary



When Code-Pega-eForm | ConcatenateEForms is run with the parameter “PerformFieldFlattening” set to “true”, the fields fail to flatten (change to read-only).

Test Activity uses Code-Pega-eForm | GenerateEform to generate the input PDF document for ConcatenateEForms Activity.



GenerateEForm Activity generates the correct document in pyEForm property, and when you download that file you see that the properties have been merged with the placeholders in eForm PDF. However, when “ConcatenateEForms” is called to flatten the document, an empty Template is produced.

This issue is observed in Pega 7.1.5 and Pega 7.1.7.

n a ‘wrapper’ activity.
2. Copy property from eFormPage.pyEForm to compositePage.pyEForms(1).
3. Call ConcatenateEForms on compositePage (with the Parameter “PerformFieldFlattening” set to “true”).

Root Cause



The root cause of this problem is a defect in Pegasystems’ code/rules.

Resolution



The issue was resolved by a Local-change.

Replace the call to ‘ConcatenateEForms’ with a Java Step as follows:

byte[] input=(byte[]) pega.findPageWithException("eFormPage", "Code-Pega-eForm").getObject(".pyEForm");
byte[] output=tools.getEFormUtils().markAllEFormFieldsReadOnly(input);
 
ClipboardPage targetPage = tools.findPage("eFormPage");
ClipboardProperty targetProp = targetPage.getProperty("pyEForm");
targetProp.setValue(output);
