Issue

When working with the script component in LC ES you may receive the following exception:

Target exception: ALC-DSC-000-000: com.adobe.idp.dsc.DSCRuntimeException: Internal error.
at bsh.BSHMethodInvocation.eval(BSHMethodInvocation.java:74)
at bsh.BSHPrimaryExpression.eval(BSHPrimaryExpression.java:69)

This exception can occur when using script similar to the following:

String clean_xml = patExecContext.getProcessDataStringValue("/process_data/myxmlbranch");

clean_xml = clean_xml.replaceAll("(<)","<");

clean_xml = clean_xml.replaceAll("(>)",">");

patExecContext.setProcessDataValue("/process_data/myxmlbranch",clean_xml);

to process XML data.  This script is working fine in LiveCycle 7, but after upgrading to ES, the script is giving this error.

Reason

There are some unexpected characters in the XML data stream.  

Solution

In this case the customer had quotation marks at the start and end of the XML stream.  They must have been stripped away automatically in LC7, but in ES, you must remove the unexpected characters and then it will process the XML without problems.

Additional Information

If a LiveCycle 7.x process that is upgraded to LiveCycle ES includes the Script QPAC, the Script QPAC may reference a script that was developed using the LiveCycle 7.x API. To ensure compatibility with LiveCycle ES, the script that the Script QPAC references must be rewritten using the LiveCycle ES API. 

In this case the getProcessDataStringValue() and setProcessDataValue() methods of the patExecContext embedded object are available in ES just as they were in LC7 so there were no changes necessary in the script.
