I am having a really weird issue with apex:InputFile.  I hide it until the user clicks on a button.  When I show it the first time and do a save, nothing goes back to the controller.  The value of my Blobs are null.

If I show it again and pick a file it works fine.

I added a text field to my dialog for testing purposes.  The text box always works.  The inputFile never works on the first call, but works fine after that.  Any suggestions on what I need to change

Here is the markup for my dialog with the Apex:InputFiles 

         <apex:outputPanel id="UploadPicture">
            <apex:outputPanel rendered="{!ShowUploadPicture}" layout="block" styleClass="SaveModal">
                     <div class="dmodal"  id="pictureModal" tabindex="-1" role="dialog" >

Is there anything I need to do with my Blob Variables before my first call to make this work on the first time.
 

Trying to develop a visual force page that will display user information.  Some of the information (About Me and profile pic) do not show up on the page when I test the website.  Shows up when I run in test mode (/apex/pagename),  This is usually a field level security issue.  
The problem that I face is field level security is not available for standard fields on the user object.   Is there a workaround?  How can I see those fields on the page?

Thanks,

Joe

I want to use the Chatter Rest API from a visualforce page since the ConnectAPi won't work for guest users

I created a connected app in a dev environment.  

I am able to get an access token as long as I use the dev login that I used to create the connected app.  I can't use a login from the sandbox instance that I am using.  Is there a way to do so

Then I try running the following function

 

    public ChatterUser getChatterUser(string userId){
        String endpoint;
        version = '/services/data/v36.0';
        
           instanceUrl = System.Url.getSalesforceBaseUrl().toExternalForm();
        
        endpoint= instanceUrl + version + '/chatter/users/'  + userId;
           HttpRequest req = new HttpRequest();
           req.setEndpoint(endpoint);
           req.setMethod('GET');
           req.setHeader('Content-type', 'application/json');
           req.setHeader('Authorization', 'Bearer ' + accessToken);
           HTTP http = new HTTP();
           HTTPResponse resp = http.send(req);
           System.Debug('Response:'  + resp);
           System.Debug('Response Body:' + resp.getBody());
}

and I get the following error

         [Status=Unauthorized, StatusCode=401]
{"message":"Session expired or invalid","errorCode":"INVALID_SESSION_ID"}

Can anyone see what I am doing wrong?  It is kind of weird that I use a dev user and try to access data data from a sandbox instance.  Does the authenticated user need Chatter access?  Is there a way that I can use a production user to authenticate?  

We have Salesforce Ultimate, Summer 2015 release. My login has adminstrator privileges and API is enabled.

I am developing a Windows forms application in C# that will use the REST Analytics API to capture report information. I am using the OAuth 2.0 User Agent flow to obtain an authentication token. I have registered my app as a Connected App, with a callback URI of sfrr:oauth2. I monitor the URLs during authentication and intercept any calls to that uri. In the Connected App setup, I selected "full" and "refresh_token, offline_access" as OAuth Scopes.

 After some initial difficulty, I am now regularly receiving my access token. However, when I tried to use that token to retreive a report, I got the 401 status (Not Authorized). At that point, I went back to the sample queries from the REST API Developer's Guide and started excuting them. The first query in the form <instance_url>/services/data/ returns a list of API versions, as expected. The next call is to <instance_url>/services/data/v34.0/. I should get a list of available resources, but I get the Not Authorized response instead. I am passing my access token in the request header using "Authorization:Bearer <access token>" and <instance_url> is the URL returned iin my OAuth User Agent results.

I saw -- once and could not find it again -- a forum response that gave the name and email address for a contact in Salesforce if your organization cannot access even though access should otherwise be available. Is that still a problem? Is there somethig else I'm missing here? Suggestions and enlightenment gratefully accepted.

 

Can we call web services through trigger?
