lopezc Problems creating an Attachment record
Hi,
i am getting the following exception when creating an attachment:
System.Exception: DML currently not allowed
Class.AttachmentSearchController.getInsertAttachment: line 18, column 44External entry point
It is failing on this line of my code: Database.SaveResult insertResult = Database.insert(attachment);
and my attachment looks like this:
Attachment Attachment:{Name=Test Attachments.txt, ParentId=003S0000005w8WiIAI, Body=Blob[0]}
Any ideas why it is failing?
I have to say that I am calling a method from my VF page within a JavaScript function:
<script>
function post_value(){
var attId = "{!insertAttachment}";
alert(attId);
if(attId != "" && attId != null){
parent.window.opener.document.getElementById('j_id0:requestForm:j_id54:j_id55:j_id57:j_id58:j_id62:att').value = attId;
parent.window.close();
}
}
</script>
And the insertAttachment method looks like this:
public String getInsertAttachment(){
String attId;
if(attachment!=null){
attachment.ParentId = '003S0000005w8WiIAI'; //Ramdom contact id
if(attachment.Name != null && attachment.Body != null && attachment.ParentId != null){
try{
System.debug('Attachment ' + attachment);
Database.SaveResult insertResult = Database.insert(attachment);
if(insertResult.getErrors().size() > 0){
} else if(insertResult.isSuccess()){
attId = insertResult.getId();
}
} catch (Exception ex){
System.debug('System exception; ' + ex.getMessage());
}
}
}
return attID;
}
Do you think this might be related?
Are you using this from a VF page or a component? If its a component, you need to set the allowDML attribute to true in the component declaration.
no, it is made within an apex:page
I changed the code. If I call the same method from an action in a commandButton it works. However it requires a second button in my page what is very annoying:
<apex:commandButton action="{!insertAttachment}" value="Send Attachment"/>
<apex:commandButton onclick="post_value()" value="Close Window"/>
</apex:panelGrid>
<script>
function post_value(){
var attId = "{!attId}";
if(attId != "" && attId != null){
parent.window.opener.document.getElementById('j_id0:requestForm:j_id54:j_id55:j_id57:j_id58:j_id62:att').value = attId;
parent.window.close();
}
}
</script>
It may be that your method starts with get - I know VF is funny about DML in constructors, and it will consider that method a property getter in some circumstances. Try removing the get and calling it insertAttachment.
