Hello developers,

I found the following example code on https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_maps_example.htm

After some minor changes to fit my needs, I got his running to show me the "nearest" customers to the account I am currently on - displayed in a visualforce page with customized markers and a Info window. 

The info window however is causing me headaches since I don't know how to store and access the values of every marker (account).

When I understand the code correctly the SOQL Query is called "querystring" and gives back accounts based on the criteria. These accounts are then stored in a List called "warehouses"

What I need now is to store the values of a couple of account fields from those accounts that got added to the list. For example Name and Owner. 

I want to reuse these as variables in thr visualforce page. Being part of the original code, this already works for: 

locations = new List<Map<String,Double>>()

<apex:repeat value="{!locations}" var="pos">

which allows me to show the geolocations of every marker I click

<apex:outputPanel layout="block">
<apex:outputText >{!pos}</apex:outputText>
</apex:outputPanel>

As being said I would need that not only for 'locations' but as well for a couple of other fields from the account. The goal is to see the corresponding accountname, owner and so on for the clicked marker.

Here is the complete APEX Code:
 

/* https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_maps_example.htm */

   
     public class FindNearbyController {
     
     public List<Map<String,Double>> locations { get; private set; }
     
     public Account currentAccount {get;set;}
     
     public Geolocation__mdt GeoConfig { get; set; }
  
     public FindNearbyController(ApexPages.StandardController stdController) {
        currentAccount  = [SELECT ID,Name, Geolocation__c,Accountinhaber_Text__c,Auftragseingangstyp_picklist__c,ShippingStreet,URL_zum_CC__c FROM Account WHERE ID =: stdController.getID()];

    }


 
      public String currentPosition { 
        get {
            if (String.isBlank(currentPosition)) {
                currentPosition = currentAccount.Geolocation__c; 

            }
            return currentPosition;
        }
        set; 
    }

    
    public Boolean resultsAvailable {
        get {
            if(locations == Null) {
                return false;
            }
            return true;
        }
    }    

    
    public PageReference findNearby() {
        String lat, lon;

        // FRAGILE: You'll want a better lat/long parsing routine
        // Format: "<latitude>,<longitude>" (must have comma, but only one comma)
        List<String> latlon = currentPosition.split(',');
        lat = latlon[0].trim();
        lon = latlon[1].trim();

        // SOQL query to get the nearest warehouses
        String queryString =
           'SELECT Id, Name,ShippingStreet,LocateCity__longitude__s, LocateCity__latitude__s  ' +
           'FROM Account ' +
           'WHERE DISTANCE(LocateCity__c, GEOLOCATION('+lat+','+lon+'), \'km\') <  3 and Kundenstatus_Direktvertrieb__c = \'Bestandskunde\' ' +
           'ORDER BY DISTANCE(LocateCity__c, GEOLOCATION('+lat+','+lon+'), \'km\') '; //+ 
        // 'LIMIT 50'; (semikolon muss dann in der zeile oben weg)

        // Run the query
        List <Account> warehouses = database.Query(queryString);
        
        if(0 < warehouses.size()) {
            // Convert to locations that can be mapped
            locations = new List<Map<String,Double>>();
            for (Account wh : warehouses) {
                locations.add(
                    new Map<String,Double>{
                        'latitude' => wh.LocateCity__latitude__s, 
                        'longitude' => wh.LocateCity__longitude__s
                        
                        
                    }
                );
            }
        }
        else {
            System.debug('No results. Query: ' + queryString);
        }
                
        return null;
    }
}
