[Wonder-disc] ERXWORepetition and indices
|
From: Mark J. <mcj...@ma...> - 2007-04-24 15:19:31

Hello all,
In one of our components, we use a WORepetition (ERXWORepetition
under the covers, of course).
I bind 'list' to an NSMutableArray, 'index' to an int, and 'item' to
'get/set' methods, which is supposed to reference the individual
items in the NSMutableArray using the index.
What happens, however, is that I get one too many calls to the 'set'
method, with the index being out of bounds (5, instead of 4), which
causes an IllegalArgumentException.
The only other thing I can add is that the repetition is guarded by
an ERXNonNullConditional, the result of which is true after the user
has uploaded a file, and there is data for the repetition to iterate
over.
Does anyone with more of a clue know what's going on here? Switching
logging on for ERXWORepetition is not much help.
Regards,
Mark Jackson
From the .wod
MappingRepetition: WORepetition {
list = importPropertyKeys;
item = currentImportKey;
index = propertyIndex;
}
From the .java
public int propertyIndex;
private NSMutableArray _importPropertyKeys = null;
public NSMutableArray importPropertyKeys() {
if (_importPropertyKeys==null) {
// Set up the array with appropriate number of entries
}
return _importPropertyKeys;
}
public void setCurrentImportKey(String value) {
NSMutableArray keys = importPropertyKeys();
keys.replaceObjectAtIndex(value==null ? "" : value, propertyIndex);
}
Stack trace follows.....
