[SalesForce] Get record ID using ApexPages.StandardController in lightning enabled org

I have old apex controller which has constructor implemented as follows:

public class RetrieveRecordId{
   Id recordId;
   public RetrieveRecordId(ApexPages.StandardController controller) {
     recordId = controller.getId();
   }
}

Now this was working fine in salesforce classic, but when org was switched to lightning ApexPages.StandardController does not get the recordId when a url na15.salesforce.com/apex/RetrieveRecordIdPage?id=a0o58000000a8qJAaQ .

I know lightning URL don't know what parameters are being passed. Is there any workaround to get params with existing apex code without changing to aura enabled controllers.

It is not an issue about Visualforce not able to passing the record Id. It is about you can't open a Visualforce page by just putting the url in the location bar in lightning experience.

In short, lightning experience is a single page app, so every visualforce page is treated as an iframed component, instead of a separate page. So you can't simply put the url in the location bar to open the page.

Instead, you need to type the below javascript in your console to navigate to your visualforce page:

$A.get("e.force:navigateToURL").setParams(
    {"url": "/apex/pageName"}).fire();

[SalesForce] serverurl and visualforce

Here is a link to what Conga Support recommends. Recomended approach 2 is what your asking about regarding the Partner_Server_URL and in my view better than approach 1 they describe.

So what you tried in your question should actually work, {!$Action.Partner_Server_URL_210} returns a Visualforce domain in a VF page contect, which does look odd, however you can actually use these domains for API calls. I've come across this when using URL.getSalesforceBaseUrl to call the Metadata API.

From Apex another approach is to use the (relatively new) method on the URL.

URL.getSalesforceBaseUrl().toExternalForm();

URL.getSalesforceBaseUrl().getHost();

etc..

If the variant of the Salesforce base URL returned by the above in Visualforce contexts does not work for you. You can try this formula. However be warned it assumes that Salesforce will continue to utilise the c.instance.visual.force.com format. But for now it works!

{!SUBSTITUTE(SUBSTITUTE(LEFT($Api.Partner_Server_URL_210, FIND( '/services', $Api.Partner_Server_URL_260)), 'visual.force', 'salesforce'), 'c.', '')}

I would still be inclined to ask Conga Support why there advice is not working for you though. ;-)

[SalesForce] Conditional parameter to change visualforce page and controller SQL

Not sure if this is what you're after but you can get the current page 'cat' parameter and build a dynamic SOQL query:

public list<News__c> getNewsItems(){
    lstItem = new list<News__c>();

    String category = Apexpages.currentPage().getParameters().get('cat');
    String query = 'SELECT Id, Name, Title__C, Content__c, Publish_Date__c, ';
    query += '(Select Id, Name, LastModifiedDate From Attachments Order By LastModifiedDate DESC) ';
    query += 'FROM News__c ';

    if (category != null)
    {
        query += 'WHERE Category__c = :category ';
    }

    query += 'ORDER BY Publish_Date__c DESC, Name DESC LIMIT :QueryLimit OFFSET :OffsetSize';

    lstItem = Database.query(query);
    return lstItem;
}
