Authoring an adaptive form using an XML schema as its form model requires basic understanding of XML schemas. Also, it is recommended to read through the following content before this article.
AEM Forms supports creation of an adaptive form by using an existing XML schema as the form model. This XML schema represents the structure in which data is produced or consumed by the back-end system in your organization.
The key features of using an XML schema are:
- The structure of the XSD is displayed as a tree in the Content Finder tab in the authoring mode for an adaptive form. You can drag and add element from the XSD hierarchy to the adaptive form.
- You can pre-populate the form using XML that is compliant with the associated schema.
- On submission, the data entered by the user is submitted as XML that aligns with the associated schema.
An XML schema consists of simple and complex element types. The elements have attributes that add rules to the element. When these elements and attributes are dragged onto an adaptive form, they are automatically mapped to the corresponding adaptive form component.
This mapping of XML elements with adaptive form components is as follows:
XML element or attribute | Adaptive form component |
---|---|
xs:string | Text box |
xs:boolean | Check box |
|
Numeric box |
xs:date | Date picker |
xs:enumeration |
Drop down |
Any complex-type element | Panel |
<?xml version="1.0" encoding="utf-8" ?> <xs:schema targetNamespace="http://adobe.com/sample.xsd" xmlns="http://adobe.com/sample.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" > <xs:element name="sample" type="SampleType"/> <xs:complexType name="SampleType"> <xs:sequence> <xs:element name="leaderName" type="xs:string" default="Enter Name"/> <xs:element name="assignmentStartBirth" type="xs:date"/> <xs:element name="gender" type="GenderEnum"/> <xs:element name="noOfProjectsAssigned" type="IntType"/> <xs:element name="assignmentDetails" type="AssignmentDetails" minOccurs="0" maxOccurs="10"/> </xs:sequence> </xs:complexType> <xs:complexType name="AssignmentDetails"> <xs:attribute name="name" type="xs:string" use="required"/> <xs:attribute name="durationOfAssignment" type="xs:unsignedInt" use="required"/> <xs:attribute name="numberOfMentees" type="xs:unsignedInt" use="required"/> <xs:attribute name="descriptionOfAssignment" type="xs:string" use="required"/> <xs:attribute name="financeRelatedProject" type="xs:boolean"/> </xs:complexType> <xs:simpleType name="IntType"> <xs:restriction base="xs:int"> </xs:restriction> </xs:simpleType> <xs:simpleType name="GenderEnum"> <xs:restriction base="xs:string"> <xs:enumeration value="Female"/> <xs:enumeration value="Male"/> </xs:restriction> </xs:simpleType> </xs:schema>
Observação:
Ensure that your XML schema has only one root element. An XML schema with more than one root element is not supported.
You can add the following attributes to XML Schema elements to add special properties to the fields of the associated adaptive form.
Schema property | Use in adaptive form | Supported in |
---|---|---|
use=required | Marks a field mandatory |
Attribute |
default="default value" | Adds a default value | Element and attribute |
minOccurs="3" | Specifies minimum occurrences (For repeatable subforms (complex types)) |
Element (complex type) |
maxOccurs="10" |
Specifies maximum occurrences (For repeatable subforms (complex types)) |
Element (complex type) |
Observação:
When you drag a schema element to an adaptive form, a default caption is generated by:
- Capitalizing the first character of the element name
- Inserting white space at Camel Case boundaries.
For example, if you add the userFirstName schema element, the caption generated in the adaptive form is User First Name.
When you double-click an element in Content Finder, a pop-up displays a field name and a property called bindRef. This property maps the tree element to the element or attribute in the schema.

Observação:
Attributes have an @ symbol in their bindRef value to distinguish them from elements. For example, /config/projectDetails/@duration.
Why I am not able to drag individual elements of a subform (structure generated from any complex type) for repeatable subforms (minOccours or maxOccurs values are greater than 1)?
In a repeatable subform, you must use the complete subform. If you want only selective fields, use the entire structure and delete the unwanted ones.
A bindRef is the connection between an adaptive form component and a schema element or attribute. It dictates the XPath where the value captured from this component or field is available in the output XML. A bindRef is also used when prepopulating a field value from prefilled (prepopulated) XML.
