Introduction
- You can follow the background on this from 2Pack/Reference.
- This method exist in different forms in the pipoHandlers module. In this case below it is taken from MenuElementHandler.
- Its purpose is to detect sub references and defer the creation of the table in AD until that sub reference has been created first.
List<String> notFounds = filler.autoFill(excludes);
if (notFounds.size() > 0) {
element.defer = true;
return;
}
Defer Process
- Each ElementHandler will flag the defer value when it detects a missing reference ID in its downline.
- During debugging, this did happened.
- Thus at the final PackInHandler end-tag, the processDeferElements() routine is called:
public void endElement (String uri, String localName, String qName) throws SAXException {
// Check namespace.
String elementValue = null;
if ("".equals (uri))
elementValue = qName;
else
elementValue = uri + localName;
if (elementValue.equals("adempiereAD")){
processDeferElements();
- The processDeferElements() then went through without getting defer.isEmpty()
private void processDeferElements() throws SAXException {
if (defer.isEmpty()) return;
do {
int startSize = defer.size();
List<DeferEntry> tmp = new ArrayList<DeferEntry>(defer);
defer.clear();
for (DeferEntry d : tmp) {
if (d.startElement) {
d.element.defer = false;
d.element.unresolved = "";
d.element.pass++;
} else {
if (d.element.deferEnd) {
d.element.deferEnd = false;
d.element.unresolved = "";
}
}
- But yet the same issue persists.
- We will have to dig from here to see why it did not call the elementHandler and create those deferred Elements.
