I'm try to using entity mapping for fields in CRM solution. I create custom opportunity form with e-mail and requiered potential customer fields. In Potential customer field you can choose an account from system, or create new. In account form I have e-mail field too, and I want map this field on e-mail field in opportunity.
I did everything in this article: http://www.magnetismsolutions.com/blog/vincent/12-03-02/Use_Entity_Mapping_to_implement_the_Clone_function_in_Dynamics_CRM_2011.aspx
And if I create a new account or choose existing in opportunity form, e-mail field not filling.
I read this answers: CRM 2011 - Using contact data on Case form In Dynamic CRM fill in the field automatically and know, that I can use js or workflow. But I out of the box feature in CRM not working for me now. I googling all day, and found peoples with the same problem, but not found solution.
It's look like bug in CRM. I use CRM 2011 in local virtual machine without rollup (because they didn't install and asked to reinstall crm server). Maybe anyone know about this strange behavior of entity mapping.
