How to redirect to default namespace vf page from managed package vf page?

Question

Question

If I'm on a managed package page, how can I link to a visualforce page in the default namespace without hardcoding the instance?

Background

I'm building a skuid page that has a custom action that sends users to a visualforce page. If I specify the relative URL for the visualforce page, e.g. /apex/MyPage, the redirect stays in the skuid namespace, i.e. https://skuid.<pod>.visual.force.com/apex/MyPage, which gives a URL not found error.

I'm able to get things working if I specify the absolute url, i.e. https://<pod>.salesforce.com/apex/MyPage, but I'm hoping to avoid hardcoding the absolute URL.

I've searched through all the Skuidify manuals and haven't been able to find any solutions there. Hoping the community has some tips here.

Answer 1

I realize this is a little late in coming, but for posterity's sake, if you append the namespace to the front of your visualforce page name, salesforce will make sure it gets the proper namespace in the full url.

So if you want your action to go to /apex/MyPage, you would do this: /apex/c__MyPage

If you're linking to something in a managed package you need to use that namespace instead: /apex/mpnamespace__MyPage

Hope that helps!

PS: We should definitely add this to our docs. It shall be done.

Use the URLFOR function in conjunction with the $Page global variable. e.g. action="{!URLFOR($Page.Your_VF_Page_Name,[params])}"

Another way of doing this is returning a PageReference to Page.Your_VF_PageName in a controller.

Yes, you can pass in parameters using this technique. Yes, it will resolve your namespace correctly.

In my opinion, using the Page global variable is a much better practice than hardcoding the namespace in the URL or using the getURL method for constructing the URL.

For more info on using the $Page global variable, see this blog post: http://www.fishofprey.com/2011/12/safe-urls-for-use-with-salesforce.html

Answer 3

Try //login.salesforce.com/apex/MyPage

In general, you can substitute login.salesforce.com for the specific instance and it will redirect you to the correct url.

Edit:

If you want to use this in a sandbox as well, you can use:

//test.salesforce.com/apex/MyPage

However, you'll need to add logic to determine if you're in production or a sandbox. If you're not an ISV and are just building this for a deterministic production org, you can use the code snippet below to determine if the code is executing on the production org:

public Boolean isSandbox() {
    return URL.getSalesforceBaseUrl().getHost().left(2).equalsignorecase('cs');
}
