The RPE Core Debug Mode has been completely redesigned in RPE 1.3 to make it useful. In the previous RPE versions the code debug mode produced a large number of trace statements in the log but those statements were not really of much help for debugging.
The new debug mode enables among other things the “Input Errors” context info as well as the extended context information for Java Script errors. Both aspects will be covered in a future article.
If an error occurs with Core Debug Mode enabled, RPE lists all the temporary files used, including downloaded data and will not delete the files until RPE is closed. Having access to these files helps to determine if the data that is received by RPE contains errors (invalid XML, unexpected data format etc). The files are automatically deleted when the RPE instance is closed.
With Core Debug Mode enabled RPE/RRDG will print at the start of any document generation details on the RPE installation. This information is commonly requested by the RPE Development and Support teams as having the exact JRE version, RRDG build number and OS information provide a good starting point for debugging.
