I am trying to use the Google Map API within a VisualForce page. When I loaded the page, at first I recieved a popup message:
"This page contains both secure and nonsecure items. Do you want to display the nonsecure items?"
I clicked yes and got the second error message:
"The google map api used on this website was registered for a different website. You can generate a new key for this web site at http://code.google.com/apis/maps/"
I clicked okay and then got the last error message:
"Sorry, the Google Map API is not compatible with this browser", which is an alert generated from the page.
Here is the code from my VF page:
<apex:page >

I can generate a new key for the correct url.
Why is the error occuring for browser incompatibility?
However when loading the visualforce page the prompt "This page contains both secure and nonsecure items." appears. When the <apex:flash is commented out, the page loads without the prompt.
I want to create a html attachment and attach it in email. I got an exception when setting email attachment body, the Apex codes like this:
=====================================================================
// Encode the html string as base64 and then create an attachment
Blob html = Crypto.generateDigest('SHA1',Blob.valueOf(htmlBody));
Attachment attachment = new Attachment();
// set attachment body - base64, and name
attachment.Body = Blob.valueOf(EncodingUtil.base64Encode(html));
attachment.Name = String.valueOf('Task.html');
// if WhatId is not null, set the attachment.ParentId to WhatId
// else set the attachment.ParentId to WhoId
if (newTask.WhatId != null) {
attachment.ParentId = newTask.WhatId;
} else {
attachment.ParentId = newTask.WhoId;
}
insert attachment;
// add the attachment to an email message line251 Messaging.EmailFileAttachment[] fileAttachments = new Messaging.EmailFileAttachment[1];
line252 fileAttachments[0].setBody(attachment.body);
line253 fileAttachments[0].setFileName(attachment.Name);
line254 mail.setFileAttachments(fileAttachments);
=====================================================================
Error message like this:
SendAlertMail: execution of AfterInsert
caused by: System.NullPointerException: Attempt to de-reference a null object
Trigger.SendAlertMail: line 252, column 21
But I can get the attachment.Name after the "insert attachment" operation.
And I can found the created attachment in related Opportunity. Can anybody give me some advices?
