I've configured Live Agent to Work with the Custom Portal without using Sites, but the pre-chat form functionality is not working.
The actual behavior is, when the customer clicks on the link to chat with a live agent and the live agent accepts, the customer is immediately able to chat with the live agent.
The expected behavior is, when a customer clicks on a link to chat with a live agent and the live agent accepts the chat, the customer should complete a pre-chat form before proceeding to chat with the live agent.
The pre chat form is created using examples provided by salesforce (I used the code in the example verbatim and I also tried using code from Pre-Chat form with some CSS.pdf). The visualforce page renders standalone, but it does not appear when the user clicks on a button. The visualforce pages are associated with the customer portal user's profile. I've used the example attached as well as the example in the official live chat developer's guide. http://www.salesforce.com/us/developer/docs/live_agent_dev/index.htm. The documentation does not provide enough information to implement the pre-chat form successfully.
Thank you in advance for your help. I have a video demonstrating the problem, if that will help http://www.screencast.com/t/Xgv8EQDb4.
