Prepopulating values in DCT

System

Hi,

We are implementing a solution where we have a web application through which business users logs in and creates content, our requirement is when user clicks on create new content link in the web application, we invoke iw.ccpro.create_form with the vpath information so that he/she uses Teamsite DCTs to create the content.

If we need to pass on some information (i.e Content Name) from the parent screen (Web application) to the child screen (DCT), how do we achieve this?

Can we pass on this additional information along with vpath so that when DCT opens up it gets prepopulated with that information (i.e Content Name)

Iam thinking about approaches like:
1. Storing the information in a cookie, and when the DCT form opens use form api to read it from the cookie and prepopulate in the DCT.
2. Use callouts in the DCT to read that information from the web application.

Any other better ways to implement?

Thanks,
Arun.
