Joget DX 8 Stable Released
The stable release for Joget DX 8 is now available, with a focus on UX and Governance.
Figure 1: ID Generator Tool Properties
Form field id. Only alpha-numeric and underscore characters allowed. Mandatory field.
If you use "id", the form will save with the "id" primary key in running sequence. Joget will not create the "id" in UUID format.
|Key in the label of this field.Mandatory field.
|Environment Variable Name
Name of the environment variable to be used to store the running number. Joget will automatically create the environment variable in Properties & Export if the name does not exist. Only letters (a-z and A-Z), numbers (0-9) and underscore (_) are allowed in the Environment Variable Name field.
Do ensure your Environment Variable Names are unique for each form in your app (meaning for each form that is mapped to a different database table name).
If you are using the ID Generator Field as "id", meaning it is a primary key value, be careful not to override the environment variable value when inporting apps: do not click the "Show Advanced Options > Override environment variables" checkbox in Import App screen.
Determines the pattern of the generated value (e.g., "REF-?????" will yield "REF-00001").
|Click the checkbox to hide this field in the form.
The value generated can be saved into the corresponding workflow variable named here.
Using a non-existent Workflow Variable name
You will get the following warning with the name printed out (e.g. status) in the server Joget log if you attempt to map to a non-existent Workflow Variable:
context attribute status does not exist in process context - adding new attributes to the process context is not allowed
The isolation defines the way in which the MySQL server (InnoDB) separates each transaction from other concurrent running transaction in the server and also ensures that the transactions are processed in a reliable way. If transactions are not isolated then one transaction could modify the data that another transaction is reading hence creating data inconsistency. Isolation levels determine how isolated the transactions are from each other.
You will only need to do this if you are using MySQL, as other databases already default to "READ-COMMITTED".
Run following queries in MySQL.
SET GLOBAL tx_isolation='READ-COMMITTED'; SET SESSION tx_isolation='READ-COMMITTED';
You will also need to set the following in your my.cnf/my.ini file.
transaction-isolation = READ-COMMITTED
