Hi, Edgar,
The NSDictionary that you receive from request().formValues()
contains NSArray values for each key. WO must presume that the
values returned are arrays of values, because some form elements
can return an array of values and WO has no way of determining
whether a given form value should be an array or not, so it opts
for the more general case, presuming that they should all be
arrays, and returns single valued arrays for the cases that only a
single value is returned for a given key.
This is a good thing to know, thank you!
Given that information, you could use request().formValueKeys() to
get the list of keys present and iterate through all the keys using
request().formValueForKey(key) to unwrap the array around each
given value to build out your own NSMutableDictionary to pass to
the EOUtilities.objectsMatchingValues method. Such as:
...
NSArray myResults = EOUtilities.objectsMatchingValues
(unwrappedFormValues());
...
private NSDictionary unwrappedFormValues()
{
NSArray keys = request().formValueKeys();
NSMutableDictionary results = new NSMutableDictionary(keys.count());
Enumeration e = keys.objectEnumerator();
while (e.hasMoreElements()) {
NSArray theValueArray = request().formValueForKey(key);
results.setObjectForKey(theValueArray.lastObject(), key);
}
return results.immutableClone();
}
The code I just wrote is:
public NSDictionary convertFormValues() {
NSMutableDictionary resultDictionary = new NSMutableDictionary();
NSArray keys = request().formValueKeys();
for (int i = 0 ; i < keys.count() ; i++) {
String key = (String) keys.objectAtIndex(i);
String value = (String) request().formValueForKey(key);
resultDictionary.takeValueForKey(value, key);
}
return resultDictionary.immutableClone();
}
I feel like having a deja vu ;)
Thanx and regards,
Edgar

Hi guys,
I'm having a problem w/ the Dictionary returned by the
DirectAction's form values. More precisely, I have a DirectAction
w/ some form values like:
...DirectAction.woa/wa/default?key1=value1&key2=value2
The method request().formValues() returns an NSDictionary looking
like that:
{key1 = ("value1"); key2 = ("value2"); }
Unfortunately, the values are wrapped into (" ") and therefore I
cannot pass this dictionary to ask the
EOUtilities.objectsMatchingValues method for database entries.
Am I doing s.th. wrong or is there an easy way to convert the
wrapped values to unwrapped versions?
Thanx,
Edgar
