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.
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();
}
Regards,
Jerry

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
