[SalesForce] How to make the entityid of point to the current user logged in

check this out : http://www.ca-peterson.com/2011/11/magic-isdtp-param.html

The isdtp param strips the header off but there is a word of caution using this. I combined this with Iframe and was able to strip the header and sidebar off

As per the blog : vw - used by the service cloud console. This is the only option that supports the new aloha theme. It strips the salesforce header and sidebar from the page. There's some small functionality degradation (enhanced lists are not longer enhanced, some ugly styles here and there) but this is your only option if you want to include chatter support through isdtp.

I had to therefore try with Iframe instead of enhanced list

https://na14.salesforce.com/500?fcf=00Bd0000003jFUo&isdtp=lt is nothing but I clicked on the case and went to the view and took the URL related to the view.

<apex:page sidebar="false" showheader="false" controller="case_ext"> 
<apex:iframe src="https://na14.salesforce.com/500fcf=00Bd0000003jFUo&isdtp=vw"/>
</apex:page>

thanks to you I learnt something new :D I felt that the most fantastic part is that you do not have to worry about mentioning saveURL and retURL explicitly since the view will return back to the same apex page after save and cancel :)

You should not be worry about case implementation on communities. Most important thing to take care about visualforce implementation of cases are profile and permissions sets for the user. Which are wide from record level to object level. In communities startup, issue comes is few standard object tabs which were selected during setup are not visible to community user.

Keep aware of what profiles are eligible for communities login and is that profile has access to case object. Profile eligible for community are given during first community setup or can be set up by going customise | communities | settings.

In my experience I came with issues with profile permissions otherwise all things are good.

In addition try to understand the logic written in apex classes which are created when you enable communities in organisation e.g. CommunitiesLandingController, CommunitiesLoginController etc. These classes are helpful in understanding the logic behind the scene how a user login and possibilities of customisations. Try to implement, if you face issue and unable to find workaround ask on salesforce stackexchange.
