KMeansPlayback page index out of bounds

[tchadwick53]

Hi there, Trying to test this system however after deploying and running the Run controller. However when i go onto the Cluster Run to see the results the playback ememed page returns list out of bounds.
Looking around i can see that during the run nothing seems to be stored within the Centroid_Matrix__c field.
{"rows":2,"elements":[[],[]],"columns":0}

Is the entery i get.
I will keep pluggin away at this, However only one test fails. Not sure if related at this point.

Any help would be greatly received.

Thank you

HI @tchadwick53

So which test is failing (that may help us narrow this down). As you can see the code hasn't been touched in a couple of years so shouldn't have anything broken.

Also if you head to the playback page whilst there is no data in the centroid matrix to replay you may be getting this error. Can you give any description of the type of data you have loaded into the system?

Thanks.

Also, are you using the visualforce page to initialize the execution? My guess is that you are missing something in initialization.
Happy to help if you can provide more details.

System.DmlException: Insert failed. First exception on row 0; first error: FIELD_INTEGRITY_EXCEPTION, Longitude value is missing : [ShippingLongitude]

is the failing test.
Yes i am using the VF page to start the processes.

is the data been used, standard account nd using the account Revenue feild

KMeansIteration.calcCentroids

for(Integer col=0;col<dimension;col++) {
	clusterTotals.setElement(num, col, clusterTotals.getElement(num, col)/size);
}

dimension is assaigned from Clustering_Run__r.Dimensions__c.
This is set within Kmeans createClustering to be what was passed from the Controller. The controller assaigns it to be 0;

Also within Kmeans.initiateClustering

for(Integer x = 0, y = dimensions; x < y; x++) {
				centroid.add(Math.random()*maxValue);
			}

again dimensions is set to be 0 and nothing looks to override. This is why tests are passing and working.
Should this not be the value returned from getCount() within the controller?

Edit..
Using GetCount() as the Dimensions gets you up and running. There are afew other things also needed doing to get this up and running.
