6 Reasons You Got the Generic Error Page

Sometimes in Visualforce, you'll have debug logging enabled for a community or portal user, but loading a page fails with no trace of what went wrong. When you look in the debug log for an explanation, all you see is that Salesforce successfully loaded the Generic Error Page configured for the site.

Before logging a case or asking a fellow developer for help, check for the following 6 common culprits.

• Are you missing any static resources, {!$Resource.__}?
• Are you missing any custom labels, {!$Label.__}?
• Are you missing any custom permissions, {!$Permission.__}?
• Are you missing any page references, {!$Page.__}?
• Are you missing any custom controller/extension properties bound on the page? This can be a problem when deploying packages among sandbox orgs.
• Are you missing any custom controller/extension actions bound on the page?

What I've also discovered, interestingly enough, is that for some reason using MavensMate v6.0.0 with Sublime Text 3, saving a Visualforce page or component skips the validation for global variables used in Visualforce.

Where's My Flow/Process in the Change Set?

If you've tried deploying flows or processes in a change set, especially in a large change set, you may have experienced some disorientation trying to find that in the Change Set detail page. For quick reference, the table below shows you what you should be looking for when examining an open change set vs. a closed change set.

Component Type	Ordered By (in Open Change Set)	Ordered By (in Closed Change Set)
Flows	Unique Name	Flow Name
Processes	API Name	Process Name

Salesforce Change Set Accelerators

Okay, so this post isn't really about web accelerators in the purest sense of the definition. But if you're frustrated with the experience of navigating and managing change sets in the UI, here are a few quick bookmarklets you can add to your browser to ease the pain.

To "install" a bookmarklet, simply drag the bookmarklet on to your browser's bookmarks bar. Or, in Internet Explorer, right-click the bookmarklet and click Add to favorites...

Change Set: Next

CS > Next

Ever notice that sometimes when you click Next to scroll through the pages of 25 components in a change set, the size of the table shifts and displaces the Next link? This simple bookmarklet clicks the Next link for you, without you having to move your mouse cursor.

Change Set: Previous

CS > Previous

Same as the Change Set: Next bookmarklet, but for the Previous link.

Add to Change Set: more (10,000 records per list page)

AtCS > more (10,000)

When adding components to a change set, especially for something like Custom Fields, you may have noticed two frustrating problems. First, clicking through multiple pages to find the record you want is a pain. Second, multiplying the pain is the fact that what you select on one page is lost when you switch to a different page. This bookmarklet sort of solves the problem by upping the size of the list to 10,000 records, which usually is enough to allow you to select and add all components of the same type at once.

Other tips

If you're planning to create a large change set as you build out your solution over multiple days or weeks, bookmarking the change set's detail page in your sandbox org should be a quick win.
