OpenXava 7.1 released

This new version of OpenXava comes loaded with exciting updates, with things you have been requesting for a long time, and we have finally had the time to include them, such as a calendar for list mode, an @Mask annotation, editable combo with value, a button to clear references, and much, much more.

In addition, we have made a Herculean effort to enhance the web security of the applications. So, if your applications are accessible on the internet to the general public and various hackers, they will now be much more secure.

To update edit the pom.xml file in your project and change the value of the openxava.version property, in this way:


Then rebuild your project:

  • With OpenXava Studio:
    • Right mouse button in your project > Run As > Maven clean
    • Right mouse button in your project > Run As > Maven install
  • Or with command line: mvn clean package

Look at the migration instructions.

Calendar in list mode

This first version of the calendar is magical and automatic, without you as programmers having to do anything. Simply having a date in the entity of the module will display a new icon in list mode, allowing you to choose the calendar format:

The appearance of the calendar is as follows:

You can create a new record by clicking on a day with the mouse, and you can edit existing records by clicking on them.

Web security enhancements.

We have made several changes to the web interface generated by OpenXava to make it much more secure and harder to hack. Here is a list of what we have fixed:

  • Fix: Denial of service vulnerability.
  • Fix: Inline JavaScript for events in HTML elements.
  • Fix: XSLT injection vulnerabilities.
  • Fix: X-Content-Type-Options header missing.
  • Fix: Cookie without SameSite attribute.
  • Fix: Application error disclosure.
  • Fix: Session ID in URL rewrite.
  • Fix: Cross-Site Scripting (XSS) vulnerabilities.
  • Fix: Data filtering in .htaccess for some URLs.
  • Fix: Content Security Policy (CSP) header not set.
If your application is public or runs in an environment where security is important, we recommend updating to version 7.1.

@Mask annotation

Now you can annotate any property with @Mask to indicate a data input mask. A mask is a string of characters that defines the valid format for input values. You can use some of the following validators:

  • 'L': The user must enter an alphabetical letter from A to z.
  • '0': The user must enter a digit.
  • 'A': The user must enter an alphanumeric character.
  • '#': The user must enter a digit, whitespace, '+', or '-'.

You can also add special characters, static whitespace, and even combine validators. For example:

private String passport;

@Mask("0000 0000 0000 0000")
private String creditCard;

@Mask("LL 000 AA")
private String carPlate;

private String customMask;

Button to clear references

Finally, there is now a button in the user interface to clear the value of a reference:

Also for the @DescriptionsList:

Combos with editable value

We have a new editor called EditableValidValues that you can assign to a String property. This way:

@Column(length = 15)
private String color;
If later we add values programmatically to make it a dynamic combo, like this:
getView().addValidValue("color", "wht", "White");
getView().addValidValue("color", "blk", "Black");
Since it uses EditableValidValues in addition to a combo with predefined values, the field remains editable. In this example, by selecting "White", you can edit it to "White beige" or enter a new value like "Yellow." These new values will not be added to the original list of options for use in other records:

New rich text editor

The JavaScript library we were using until now, CKEditor 4, does not support the use of Content Security Policy, which means it cannot be used in a secure environment. Due to licensing issues, we cannot update to CKEditor 5, so we had to opt for TinyCME. The result is not only a more secure library but also a much more modern rich text editor:
