I've created an unmanaged package that consists of:

  • several fields for a Lead object,
  • and one Visualforce page (Pages_Visited)

During the installation of this package I get the following error: enter image description here

The mentioned field is certainly present in the package: enter image description here

And the Pages_Visited Visualforce page works perfectly fine on my Developer org. It references the field like this:

<span id="gaconnector_pages_visited_list">{!lead.zuevsoftware__Pages_visited__c}</span>

I've tried installing this package on two orgs, one of them completely clean (no custom fields, no Apex triggers, nothing custom). And both times I received the same error.

What could be causing this problem?

  • Might be due to namespace if its a managed package.

  • @RCS it's a managed package

    Just remove the namespace before custom field and try

It seems to be namespace issue: Try replacing to below syntax:

<span id="gaconnector_pages_visited_list"><apex:outputField value="{!lead.Pages_visited__c}" /> </span>
