Q: 11

HOTSPOT You’re developing a case management application. Currently, users can view a list of all cases designed using a a!forEach() loop from a record query. Users can navigate to the case summary page which shows the case details in a two (2) column layout. Users are also able to update the case details. During the last round of UAT testing, users reported that the tool was not intuitive to use. Match each feedback comment to the suggested UI/UX improvements. Note: Each UI/UX improvement will be used once, or not at all. To change your responses, you may deselect your response by clicking the blank space at the top of the selection list.

Q: 15

You run a report on different employee transactions by using a View. You encounter the following error: "a!queryEntity: An error occurred while retrieving the data." What is the most likely root cause of this error?

Options

Correct Answer:

Explanation

The a!queryEntity function requires a data store entity to have a designated primary key to uniquely identify and retrieve each row of data. While database tables usually have a primary key defined, database views do not. Therefore, when mapping a view to a Custom Data Type (CDT) to be used as a data store entity, you must manually designate one of the CDT fields as the primary key using the @Id JPA annotation. Failure to do so prevents Appian from processing the view's data, resulting in the "An error occurred while retrieving the data" error.

Why Incorrect

B. The view contains a large number of rows, requiring more time to fetch the data.

This would typically cause a performance-related timeout error, not a generic data retrieval failure. The error message does not indicate a timeout.

C. The rule contains a missing syntax.

A syntax error in an expression rule is usually caught by the design-time editor and would prevent the rule from being saved or, if executed, would produce a specific syntax-related error message, not a data retrieval error.

Data Store

"Create a Data Store Entity from a Database Table or View": "For database views

you must select a column to use as the primary key. Appian does not support views that do not have a primary key. If your view does not have a column that is always unique

we recommend adding a column that can act as a primary key

such as by using the ROWNUM pseudo column in Oracle." This source confirms the mandatory requirement of a primary key for a view-based entity.

2. Appian Documentation

Custom Data Type (CDT) Design

"JPA Annotations": The @Id annotation is listed for specifying the primary key field for an entity. This is the specific mechanism used within the CDT's XSD file to map a field to a primary key

which is essential for view-based entities.
