Changing the default lookup type of a regarding field

When opening a lookup that can select from multiple entity types, you may want to use a different default entity in the lookup dialog. The following script changes the default entity of the regardingobjectid field in an activity to contacts:


if (crmForm.all.regardingobjectid != null) {
    crmForm.all.regardingobjectid.setAttribute("defaulttype", "2");


The 2 refers to contact, just change to reflect the object you wish to set as the default.
