We have implemented the live Agent functionality in Production. We have also our portal users for whome this chat functionality provided. Through portal home page , clients can initiate chat (chat button provided on portal). Also we have implemented the Prechat form in order to receive the data like Name, email, Account..

This is working fine but clients needs to fill out these details in Prechat form, which is not feasible since they are Portla users. So I am prepopulating these details like name, email in Pre chat form. Used prety simple code at VF (mentioned below) , this is working fine in Salesforce preview. However, when used on Portal , prechat form is not reflecting the correct Name , email in Pre chat form. In the name field this is reflecting Sitename and in email email this is using the by default site user email id.

We want when, every client logged in Portal and initiating the chat , in prechat form , Client name and email should be in user context....

Please let me know any workaround / solution how to resolve this.

I will really appreciate this ....
