Static view

In static view, all form data is read at the time the form is opened, after which the obtained data is converted:

• either to print view - image or excel. Print view is also often referred to as a report
• or to structured view - one of the corresponding data formats (e.g. XML, JSON, CSV, DBF)

As a rule, structured view is used to load data into other information systems, while print view is used to view data by a user and print to a printer.

Empty object group

In static view, any form has a predefined empty object group, which is considered to be the first object group on the form, does not contain any objects and is considered to be the display group for properties/filters without parameters. Accordingly, in this display group there is always a maximum of one empty object collection (exactly one, if there are no filters without parameters).

Object group hierarchy

To display information in static view , the form's object groups must be organized in a hierarchy in which data for object groups will be a kind of "nested" in each other. For example, if we have object groups A and B, and A is the parent of B, then in static view all properties of A will be displayed first for the first object collection from A, then all the properties of B and of the pair (A, B) for all object collections from B, then similar information will be displayed for the second object collection from A and all sets of objects from B and so on.

Building object group hierarchy

The platform builds object group hierarchy based on the form structure as follows:

• First, relations between object groups are built according to the following rules:

  • object group A depends on object group B if A appears in the list of object groups later than B and the form has a property or filter that takes objects from A and B as input arguments (B should not be a group-in-column of this property).
  • any object group A depends on the empty object group
  • group A indirectly depends on group B if, again, A appears later than B and there is an object group C which depends on both A and B

• After the relations are built, the hierarchy is constructed in such a way that the parent of object group A is the group B that is latest in the object group list on which A depends (directly or indirectly).

info

As follows from the algorithm, the empty object group is always the only root group of the constructed hierarchy

An example of constructing object group hierarchy

FORM myForm 'myForm'
    OBJECTS A, B SUBREPORT, C, D, E
    PROPERTIES f(B, C), g(A, C)
    FILTERS c(E) = C, h(B, D)
;

The hierarchy of groups of objects for this form will be constructed as follows:
