Hi Greg,
Here is a modified InstallScript that contains methods which should enable you to auto-create skuid__Theme__c records when installing your package into a customer’s org. In this example I’m assuming that you’re only including one Theme with your package, whose Name is “StockCheck” and which is stored in a Static Resource that is included in your package(very important!) called “StockCheckTheme”. This is just an example, you’ll need to to adjust to be whatever your Theme’s Name and Static Resource Name are.
Also, this post-install script does NOT automatically set the Org-Default Theme preference or change any Profile/User theme settings to be your Theme. If you want to do this this is possible but would take some more code.
public without sharing class StockCheckInstallScript implements InstallHandler {
public static final String NAMESPACE_PREFIX = ‘gbc’;
public static boolean IsRunning {
public get {
if (IsRunning==null) IsRunning = false;
return IsRunning;
}
public set;
}
public void onInstall(InstallContext ctx) {
IsRunning=true;
RefreshPagesInModule(NAMESPACE_PREFIX);
CreateDefaultThemes();
IsRunning=false;
}
public static List RefreshPagesInModule(String module) {
// See if a StaticResource containing new pages for this module yet exists
StaticResource sr = [

from StaticResource
where Name = :(module + ‘Pages’)
and ((NamespacePrefix = NULL) OR (NamespacePrefix = :module))
limit 1
];
// The new Pages for our module that we will be inserting
List newPages
= (List) JSON.deserialize(sr.Body.toString(),List.class);
List layoutFields = new List{
skuid__Page__c.skuid__Layout__c,

// Get rid of the Ids so that upsert will proceed
p.Id = null;
// Ensure that unused Layout fields are set to null

if (p.get(f)==null) p.put(f,null);

List cr = Database.upsert(newPages,f,false);

return new Map>{

// create them!
