When docx or odt report is generated, there is 3 steps that is done :
- orginal : this step load docx/odt in a Java structure XDocArchive which store each entry of the docx/odt.
- preprocesed : this step modify some XML entries (content.xml for odt, word/document.xml for docx) to replace mergefield/input field code with static content, add #foreach automaticly before row...A new XDocArchive is created with the XML entries modified.
- generated : this step consist to use preprocessed XDocArchive and merge some XML entry (content.xml for odt, word/document.xml for docx) with Java model with template engine (Velocity/Freemarker) to generate report.
