I followed the example code line by line from:
How do I integrate Salesforce with Google Maps?
I am not receiving any errors but my Map is blank. The map displays the zoom and position toggle but nothing else.
Any ideas on why?
Here is my Controller Code and Page Code Below
public class mapController2 {
public String address {get;set;}
private List<Account> accounts;
public void find() {
// Normal, ugly query.
/* address = 'USA';
String addr = '%' + address + '%';
accounts = [SELECT Id, Name, BillingStreet, BillingCity, BillingCountry FROM Account
//WHERE Name LIKE :addr OR BillingStreet LIKE :addr OR BillingCity LIKE :addr OR BillingCountry LIKE :addr];
WHERE BillingCountry LIKE :addr];*/
// address = 'Austin';
String addr = '*' + address + '*';
// Or maybe a bit better full-text search query.
List<List<SObject>> searchList = [FIND :addr IN ALL FIELDS RETURNING
Account (Id, Name, BillingStreet, BillingCity, BillingState, BillingCountry)];
accounts = (List<Account>)searchList[0];
}
public List<Account> getAccounts() {
return accounts;
}
}
Page Code
<apex:page controller="mapController2" tabStyle="Account">

Any text data (free text, not picklists, checkboxes etc.) will do.
