"Validation error" message after migration

Support
#1

After migration to Studio 6.7, I can’t open the layout of several screens. When selecting the “Layout” tab at the screen editor, a pop up appears with the message “Validation error” and no other message in the console. This prevents the layout screen from opening.

This error appears in some “complex” screens. I can edit other “simple” screen. It seems there is a validation layout error, but instead of showing what the error is in the layout editor, it stops there.

Thanks,

Alejandro

Still with this problem, any ideas how to solve it ?

Thanks,

Hi,

Could you please provide a sample of XML markup which cannot be opened.

Regards,
Gleb

#4

I have the same problem. This is my XML:

servico-atividade-mes-browse.xml (1.9 KB)

#5

I removed the “Excel” button and the validation error was fixed.

#6

When I set the property ‘action’ of any button, I receive:

Unable to set property 'action’
java.lang.NullPointerException

This seems to be the root cause of Validation Errors of existing screens.

#7

substance-edit.xml (19.7 KB)
here is one of the screens with validation problems.

#8

Unfortunately, I cannot reproduce case with Excel action. What CUBA Studio version do you use?

#10

The only error I have is:

Datasource ghsAttributesDs: Property field is empty

Because I don’t have the correct data model, so it’s expected. As for the rest XML descriptor, I don’t see any critical issues and I can open the Layout tab. What particular CUBA Studio version do you use? Try to open the screen in the IDEA IDE with CUBA Idea plug-in installed and check if there are any errors.

#11

In my case, I opened the XML and controller in IDEA and it found no errors at all.

When tried to edit the screen (after seeing the XML source file), I got the following stack trace error:

Still stucked at this problem.

#12

BTW, I’m using Studio 6.7.1. It was working without problems in 6.6.x

#13

I have migrated from 6.6.x to 6.7.2. After that, I am receiving Validation Error for all screen with buttons. If I remove the button action, the Validation Error is gone.

If I create a brand new project, the problem does not happen.

#14

Thank you for reporting the problem, we’ve created a YouTrack issue.

#15

Unfortunatly we still can’t reproduce the ‘Validation error’ issue.

Could you please attach some sample project with this error reproducing?

Nevertheless, additional logging was provided for screen opening process. So as soon Studio 6.7.2 released, please provide us log file containing described error.

#16

Hi,
I also have this problem.
I am using Studio 6.7.1 and platform 6.7.2.
Project was migrated from an earlier version don’t remember exact version.
I atached a test project
test.zip (627.0 KB)

When i try to save the screen i get the following error:

Hi!

Thanks a lot for your test project!
Problem identified and will be fixed in next bugfix release.
See YouTrack issue

#18

Hi @gaslov,

Is there a way to get this fix in advance? Is there a workaround?

Thanks,

Alexandre

#19

Hi,

I’m afraid you can’t get the fix in advance. But the good news is that Studio 6.7.2 is expected to be released tomorrow.

As a temporary workaround, you can try to remove com.haulmont.cuba packages with localization files from your project.
For sure this will break your application localization, but the screens should be available for editing.

Best regards,
Alexander
