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();
}
Umm, request().formValueForKey("thekey"); should return a single
value. Calling valueForKey on the dictionary or formValuesForKey on
the request will return an array.

Yup, you're right.
I wrote the routine quickly this morning knowing that fact, but I had
so focused on why WO returns arrays for each of the values, that I
automatically and erroneously extracted the value from the
nonexistent array. Since I wrote the routine with Mail.app as my
editor, it didn't catch that. :-)
More coffee!

Re: DirectAction: NSDictionary of the form values
from your description, it look like 'formValues()' wrap all values in
an array (from the doc).
formValues()
Returns an NSDictionary containing all of the form data
with names for keys and NSArrays containing the value(s)
associated with those keys for values.
so to get "value1", you would do :
String value1 = (String) request().formValues().valueForKey
("key1").objectAtIndex(0);
Or simply use 'formValueForKey':
String value1 = (String) request().formValueForKey("key1");

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

This is a good thing to know, thank you!

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 ;)
