Design-time limitations in express mode
Valid from Pega Version 7.1.9
Some limitations apply when you develop an enterprise application in express mode. At design time, some features are disabled or have limited options when you configure them in Designer Studio and switch to express mode. The use of these features does not restrict the run-time behavior of your application; however, you cannot change the configuration of these features unless you switch from express mode to Designer Studio.
For more information about each limitation and the recommended action to take, see the following information:
- Pega 7.2.2 Design-time limitations in express mode
- Pega 7.2.1 Design-time limitations in express mode

Primary key constraint error when using JBoss
Valid from Pega Version 7.1.9
A primary key constraint violation exception might occur in the following situation: you use JBoss EAP 6.4 and SQL Server 2012 with a JDBC 4 driver, and you use two or more file listeners or JMS MDB listeners with concurrent threads that create work objects that use multiple files. If a primary key constraint violation exception occurs in this situation, update the data source configuration file to set the jta parameter to true. For example, set <datasource jta="true" jndi-name-"java:/jdbc/PegaRULES>.
New dynamic setting to manage validation of hidden fields
Valid from Pega Version 8.6.4
Pega Platform™ version 8.6.4 introduces a new DSS setting for Theme Cosmos and other section-based applications. The validateHiddenField setting controls whether the application validates fields that you hide through visibility rules. By default, validateHiddenField is set to true
, which means that the application fields are validated for completeness even if they are not displayed in the form. You can also switch off this functionality by changing the setting value to false
.
