Special characters in i18n message key produces UnsupportedOperationException at runtime

Bernat · June 26, 2018, 7:56am

Hi,

If you use special characters for an i18n message key, you will receive the following error at runtime:

UnsupportedOperationException: Unsupported resource string format: ‘msg://Genérico.campo_obligatorio’, messagesPack=null

Studio should have a validation rule for i18n keys as there is for entity class names.

Thanks.

Hi,

Could you please provide the full stack trace or log file?

After changing Genérico to Generico error disappeared.

Unfortunately, we cannot reproduce the problem. We will be able to help you if you send us a small sample project along with reproduction scenario that demonstrates the issue.

I’ve reproduced the same FieldGroup with requiredMessage set to msg://Genérico.campo_obligatorio. It works as expected: untitled.zip (80.1 KB)

We are using UTF-8 for all the resources, thus it should work for all the Unicode characters.

Bernat · June 26, 2018, 1:47pm

Hi Yuriy and thanks for taking the time to reproduce the issue.

I have created a new project and followed these steps to get the error happening:

Create new Entity at the Data Model tab
Create new Attribute with default type
In the Validation panel for the attribute, click on not set next to NotNull validation
Enable and click on the world icon
Click Add to create a new message key
Enter “Genérico.not_null” and keep pressing OK until all changes are saved
Select new entity and click on New -> Generic UI Screen
Click on Run -> Start application server
Open the browser and navigate to the app
Log in, click on Application and select the previously created entity
A pop up with the following should appear:

Here is the zipped project: TestI18n.zip (79.7 KB)

The project was created using version 6.9.1 with no changes made to default configuration.

artamonov · June 26, 2018, 2:19pm

Thank you for the reproduction scenario, now I see the problem. It is related only with messages defined in entities.

As a workaround, you can specify full message path with package:

@NotNull(message = "{msg://com.company.testi18n.entity/Genérico.not_null}")
@Column(name = "TEST_ATTRIBUTE")
protected String testAttribute;

I’ve filed the issue: BeanValidationMessageTransformer supports only ASCII symbols in message keys · Issue #46 · cuba-platform/cuba-gradle-plugin · GitHub
