Always add <apex:pagemessages/> at the beginning of your VF page to see if there are errors in loading/submitting VF page. If something underneath the Visuarlfoce is wrong, you don’t see anything (no clear log at least)! I was using the automatic SOQL generation of the “Object__c” standard controller, and to do this I usually use […]

[Visualforce / Tip] Always add a
[Apex / JavaScript] What is @RemoteAction? Baby don’t hurt me, don’t hurt me, no more!
2 hours to find out why @RemoteAction was hurting me. This is related to Cloudspoke’s challenge POC – Bootstrap Visualforce Pages (which I haven’t submitted neither).

[Salesforce / Canvas] Set up a minimum Canvas App (Java style)
This new post is about setting up a Force.com Canvas App and doing beautiful things with it. It comes from an old challenge I won (see Cloudspokes.com blog post), evenif in that case I used Javascript to get the session infos. What is a Canvas App? In simple words it is a way to integrate […]

[Salesforce / Visualforce] jQueryUI + Dialog + Postback
I wanna show you what happens if you do a postback inside a modal jQuery UI dialog. This is a problem I had some times ago making this challenge on Cloudspokes. We have a simple controller: public class MyController { public String value{get;set;} public void anAction() { if(value != null && value.length()>0) ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR ,’Variable […]
[Salesforce / Apex] POST Mutipart/form-data with HttpRequest
17/10/2014: the solution has been improved. Datails at the end of the post. Grandma says you cannot post a Mutipart/form-data using an HttpRequest in APEX? Well, if she says this now you can tell her this is no more true! All comes from a CloudSpokes challenge (here is the link)…at the time of starting the challenge […]
