[SalesForce] GETRECORDIDS on Activity List view

I created an activity list button to select multiple records from a list view and process in a visualforce page/apex controller. I used GETRECORDIDS($ObjectType.Event) to get Ids of selected Event records. BUT it returned ids of tasks too. Then I replaced $ObjectType.Event by $ObjectType.Task the returned result was same. I then replaced it by $ObjectType.Contact still the returned result was same.

My question is if selected ids are returned irrespective of the $ObjectType.object then why it is there?
Am i missing something?

Here is the code on the Button:

var ids = {!GETRECORDIDS($ObjectType.Event)}; 
if (ids.length) { 
window.location = '/apex/mypage?ids=' + ids.join(','); 

} else { 
alert('Select one or more Records'); 
}

The list button you have created on Activity(combination of tast and event in salesforce) object, so it will always return the ids of activity(Event+Task) regardless of what type you are using with $ObjectType.

So the conclusion is you can use only type for which your list button is created.

example if you create a list button on contact then in the javascript, you can use GETRECORDIDS($ObjectType.Contact) or even pass any other object name or any value like GETRECORDIDS('XXX') still it will return the contact ids only. function GETRECORDIDS requires one parameter so you need to pass the value for the first parameter.

[SalesForce] Creating a custom list-view button that handles multi-record selection

Assuming your not adverse to a bit of Apex I would recommend you use the StandardSetController for most of this. It is specifically designed to be used with VF pages that extend the ListView and selection functionality. Here is an example I created for you, called Bump Case Priority.

enter image description here

It presents a page to confirm the changes and then a Confirm button. I built this using a Visualforce page and an Apex class shown below. The key method on the StandardSetController class for both the page table binding and in the updateCases method is getSelected.

<apex:page standardController="Case" extensions="CasesController" recordSetVar="cases" action="{!bumpCases}">
   <apex:form >
       <apex:pageBlock title="Bump Selected Cases">
            <apex:pageBlockButtons >
                <apex:commandButton action="{!updateCases}" value="Confirm"/>
            </apex:pageBlockButtons>
            <apex:pageBlockTable value="{!selected}" var="case">
                <apex:column value="{!case.casenumber}"/>
                <apex:column value="{!case.subject}"/>
                <apex:column value="{!case.priority}"/> 
            </apex:pageBlockTable> 
        </apex:pageBlock>
    </apex:form>    
</apex:page>

NOTE: The 'recordSetVar' attribute on apex:page tells the platform this is a ListView page. This is very important for binding this page to your Custom Button. Though less important in the context of this demo as the variable it creates gives all records and not the selected ones.

public with sharing class CasesController 
{
    private ApexPages.StandardSetController standardController;

    public CasesController(ApexPages.StandardSetController standardController)
    {
        this.standardController = standardController;
    }

    public PageReference bumpCases()
    {       
        // Get the selected records (optional, you can use getSelected to obtain ID's and do your own SOQL)
        List<Case> selectedCases = (List<Case>) standardController.getSelected();

        // Update records       
        for(Case selectedCase : selectedCases)
        {
            if(selectedCase.Priority == null) 
                selectedCase.Priority = 'Low';
            else if(selectedCase.Priority == 'Low')
                selectedCase.Priority = 'Medium';
            else if(selectedCase.Priority == 'Medium')
                selectedCase.Priority = 'High';
        }       

        return null;        
    }

    public PageReference updateCases()
    {       
        // Call StandardSetController 'save' method to update (optional, you can use your own DML)
        return standardController.save();   
    }
}

NOTE: You can perform the update of the records in the 'bumpCases' method in one and effectively not provide the confirmation. However, be warned that this will likely raise a concern if your putting your code through Salesforce Security Review. As, rightly so, they see code updating the database as part of a page navigation a security risk.

Finally, you need to create your Custom Button under Customise > Cases > Buttons and Links and then use Customise > Cases > Search Layouts to add your button to the List View layout. This is what my button definition looks like.

[SalesForce] Get list of contacts from search layout

You can add a "List Button" set to "Execute JavaScript" with this JavaScript:

var ids = {!GETRECORDIDS($ObjectType.Contact)};
if (ids.length) {
    if (ids.length <= 100) {
        window.location = '/apex/MyPage?ids=' + ids.join(',');
    } else {
        alert('Select 100 or less');
    }
} else {
    alert('Select one or more Contacts');
}

Your Apex page (MyPage here) then just has to split the "ids" parameter to get the set of selected ids.

The limit of 100 selected items is imposed because 2k characters is generally considered the longest URL that works safely everywhere.

To address the comment that more than 100 selected objects may need to be supported, here is how to use a POST instead of a GET:

var ids = {!GETRECORDIDS($ObjectType.Contact)};
if (ids.length) {
    var form = document.createElement("form");
    form.setAttribute("method", "POST");
    // This must be the full URL
    form.setAttribute("action", "https://c.na15.visual.force.com/apex/Target");
    var hiddenField = document.createElement("input");
    hiddenField.setAttribute("type", "hidden");
    hiddenField.setAttribute("name", "ids");
    hiddenField.setAttribute("value", ids.join(','));
    form.appendChild(hiddenField);
    document.body.appendChild(form);
    form.submit();
} else {
    alert('Select one or more Contacts');
}
