Re: WOBatchNavigationBar and qualifyDisplayGroup()

I have tried this before as well but haven't had any success.

The way I got round it was to use an NSArray as a class variable and  
reference it.  I also had to abandon the WOBatchNavigationBar and  
create my own.  It's easy though.

All you do is create the table the way you want it (I use 3 columns in  
a table that is 80% of the window width) and add your strings and  
buttons etc.  Then use the methods from the WODisplayGroup to hook it  
up.  You will use the displayPreviousBatch, displayNextBatch,  
currentBatchIndex and batchCount.  For the total objects found you will  
need to hook up the foundObjects.count.

So:

public NSArray foundObjects = null;

Then in my search method:

foundObjects =  
EOQualifier.filteredArrayWithQualifier(productDetailDisplayGroup.allObje 
cts(), new EOOrQualifier(qualifier));

Then in the WO, hook up the foundObjects.count to your  
totalFoundObjects string.

I also put a conditional around mine so it only displays the bar if  
there are objects in the array.  If there are no objects it displays a  
"No Matching Product Records Found" message instead.

As far as I can tell there is no way in which to use the  
detailDisplayGroup with the WOBatchNavigationBar.  This is exactly how  
I got round the issue and I use it in a number of applications for  
clients.  If you do find a way to use the WOBatchNavigationBar in this  
way, be sure to post it :)

If you need any more help, let me know.

Good Luck.

Larry.

  I've I use qualifyDataSource() I do not get the results I'm looking  
for.

  My search currently reads as:

  productDetailDisplayGroup.queryMatch().setObjectForKey("N",  
"product.obs");

  productDetailDisplayGroup.queryMatch().setObjectForKey("RES",  
"pricelevel");

  NSArray args = new NSArray(new Object[] { "IPOD", "SW", "MON", "ACC"  
});

  String qualifierString = "(product.brand = %@)";

  EOQualifier qualifier =
  EOQualifier.qualifierWithQualifierFormat(qualifierString, args);

  EOFetchSpecification fs = new EOFetchSpecification("productDetail",
  qualifier, null);

  EOEditingContext ec = session().defaultEditingContext();

  NSArray tempResultsArray = ec.objectsWithFetchSpecification(fs);

  productDetailDisplayGroup.setObjectArray(tempResultsArray);

  productDetailDisplayGroup.qualifyDisplayGroup();
