I have a persistent object, Category (code below) (it has no links to
other persistent objects) it was working fine and has just stopped
saving all of a sudden.
Basically i have a hardcoded list that i want to commit to the
database on the first time which is what this code does.
There haven't been any changes to the object and the code to make it
persistent. i have deleted the databases and indexes. I have stepped
through the code and all lines execute
I am trying to get ideas on what to try, Really need to get it working
as i have just finished my app and was just about to release.
The mnethd for saving is:-
-------------------------------------------------------------------------------------------------------------------------------
public void createCategories() {
PersistenceManager pm;
pm=PMF.get().getPersistenceManager();
int ctrTop=0;
for (String[] catTop: Category.itunesCategoriesTexts) {
int ctr = 0;
Category parent = null;
for (String cats: catTop) {
Category c = new Category();
c.setText(cats);
c.setTextClean(Category.cleanCatName(cats));
if (ctr>0) {
c.setParent(parent.getId());
} else {
parent=c;
}
pm.makePersistent(c);
ctr++;
}
ctrTop++;
}
pm.close();
}

The code for the Category persistent object is here:
