             Summary: Error component renders unstyled with Bootstrap 4
                 Key: TAP5-2712
                 URL: https://issues.apache.org/jira/browse/TAP5-2712
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.8.0, 5.7.3, 5.6.4, 5.7.2, 5.7.1, 5.6.3, 5.7.0, 5.6.2, 5.6.1, 5.6.0, 5.5.0
            Reporter: Thiago Henrique De Paula Figueiredo


As noticed by [~vlamp] in the Tapestry dev mailing list:
{quote}Using Tapestry's BeanEditor component with Bootstrap 4, I'm trying to get
validation error messages appear with a red font color like they used to
with Bootstrap 3.

Trying to understand from the Tapestry source code why Tapestry outputs
Bootstrap v3-style "help-block" instead of v4-style "form-text" [1], I
became aware of the SymbolConstants.ERROR_CSS_CLASS configuration symbol.
Setting its value to "form-text text-danger" did the trick for me.

Two recommendations for improvement:

First, the Configuration page of the Tapestry website [2] doesn't mention
the ERROR_CSS_CLASS configuration symbol. It should be added to make it
easier for other Tapestry users trying to solve the same problem or similar
problems.

Second, importing  the Bootstrap4Module should provide validation messages
with a red font color as the default.{quote}
