Hi Guys,

Yet another question from my side. I'll quickly explain what I'm trying to do: I've created a visual flow in which employees go through a contract wizard. It creates a contract record with the information they filled in and then submits it for approval. I made it so the user has to do as few interactions as possible because we all know users can be stupid and need to have as few room as possible to forget things.

For all the contracts the process is finished when the wizard is done except for one contract type. For that type they need to upload a file. Since visual flow doesn't have that function I needed another way to achieve the upload.

What I did was to let the flow construct an url that when clicked showed them to the upload screen and also passed a return url so that they would be returned to a flow in which their submission would be submitted for approval. The url that is created in the flow looks like this:

/p/attach/NoteAttach?pid={!var_RecordID}&parentname={!ret_ContractNumber}&retURL=/flow/Simple_Approval_Tool?var_RecordID={!var_RecordID}

 And when clicked this url works perfectly. The problem is that people don't click the link, they forget and just click finish. So I had to set this url as finish location and thus came the following code. 

In principle it works so save your time scrutenizing the whole thing ;) The only part that doesn't work is the actual redirect to the "pp" page. I must confess though, that I do not get why the redirect works since in the VF page the reference is to {!OID} and in the controller we only have "getOID()". But it works for the "other" contracts and redirects them to the newly created (and submitted) record.

For the VisualForce page I have:

<apex:page Controller="ContractRequestFlowController" TabStyle="Account">
    <br/>
     <flow:interview name="Contract_Request_Wizard" interview="{!myflow}" finishlocation="{!OID}" />
</apex:page>

 And for the controller I have:

public class ContractRequestFlowController{
public Flow.Interview.Contract_Request_Wizard myFlow { get; set; }

public String getmyID() {
if (myFlow==null) return '';
else return myFlow.var_RecordID; //Retrieves var_RecordID from the flow. Important is that the var isnt private!
}

public String getRecordTypeID() {
if (myFlow==null) return '';
else return myFlow.var_ContractRecordTypeID;
}

public String getContractNumber() {
if (myFlow==null) return '';
else return myFlow.ret_ContractNumber;
}      

public String createUploadUrl() { //creates a string which is the upload url
return '/p/attach/NoteAttach?pid=' + getmyID() + '&retURL=/flow/Simple_Approval_Tool?var_RecordID=' + getmyID(); //works until I refer it to the Simple Approval Tool
}// As soon as '=/flow/Simple_Approval_Tool?var_RecordID' is added behind retURL= the system breaks.
    
public PageReference getOID(){
    PageReference p = new PageReference('/' + getmyID()); //This works like a charm!
    PageReference pp = new PageReference(createUploadUrl());//
    p.setRedirect(true);
    pp.setRedirect(true);
    if(getRecordTypeID() == '012400000005ZPM'){ //RecordTypeID of a specific type of agreement for which people need to upload a file.
   	return pp;}
    
    else{
        return p;}
}

}

 Again this works perfectly. It redirects when it needs to, it matches the record type ID perfectly. The problem lies in the fact that I cannot let it refer the retURL location to: 

/p/attach/NoteAttach?pid=' + getmyID() + '&retURL=/flow/Simple_Approval_Tool?var_RecordID=' + getmyID()

It does work If I refer it to:

/p/attach/NoteAttach?pid=' + getmyID() + '&retURL=' + getmyID()

 It fires:

Invalid Page Redirection
The page you attempted to access has been blocked due to a redirection to an outside website or an improperly coded link or button. Please contact your salesforce.com Administrator for assistance.

Any clue on how to fix this? Again, if I enter the link manually in the address bar it does work.

I was thinking I might redirect to a different VF page that would include an upload screen and then submit the record for approval, but I'm afraid I might run into the same issue there.

Any ideas would be much appreciated!

---edit---

Someone just pointed out that it might be possible to combine the fact that there is a newly created record (of the certain type) and the fact that a file was uploaded in a trigger which would then automatically submit the record for approval - thus eliminated the neccecity to set the redirect to a flow or apex that submits for approval. Any thoughts on this would also be appreciated.
