This type of ITEM is used to embed another FORM into a parent FORM.

This ITEM is very similar to ITEM TYPE: "FORM". The main differences are:

The ITEMS enclosed in the TRAINER ITEM should always be displayed in a popup dialog in the client application.
It is possible to define a number of repetitions. The purpose of this property is to repeat the The ITEMS enclosed in the TRAINER ITEM as many times as desired.

This ITEM can be used to avoid creating FORMS with a large number of questions, and instead of that, the questions my be grouped in separate sub-FORMS. Then it would be possible create a simpler FORM that uses this ITEM TYPE to embed the sub-FORMS by defining a reference the them.

As a result, the parent FORM would appear to be composed by the union of all the ITEMS in the sub-FORMS

Editability of the embedded ITEMS

The questions of the embedded FORMS will only be editable when

The parent FORM is in OPEN state
The embedded FORM is 'HIDDEN'
The embedded FORM belongs to the same TASK than the parent FORM

Otherwise the questions of the sub-FORM will be embedded but not editable (can be used to display summaries of other FORMS

Referencing sub-FORMS

The reference to a sub FORM is calculated using the FORMULA property if this ITEM type. The calculation of the FORMULA may return:

A direct FORM reference that refers to a specific FORM
A FORM_CODE: in this case, the system will look for the most recent FORM with the indicated FORM_CODE that belongs to any ADMISSION of the PATIENT

Execution of ACTION formulas

When the FORM embedded with a FORM ITEM includes ACTION FORMULAS, the ACTION will be executed when the last open ACTIVITY including the embedded FORM is closed.
