Method Detail

writePrefix

public void writePrefix(org.apache.tapestry.IMarkupWriter writer,
                        org.apache.tapestry.IRequestCycle cycle,
                        org.apache.tapestry.form.IFormComponent component,
                        org.apache.tapestry.valid.IValidator validator)

This method is overwritten so that the error message generated during server-side validation actually appears next to the field in question. Don't be confused by the method names, there is a complimenting writeSuffix for fields, as well as a pair of writeLabelSuffix/writeLabelPrefix methods to do the same to labels.

Specified by:

writePrefix in interface org.apache.tapestry.valid.IValidationDelegate

Overrides:

writePrefix in class org.apache.tapestry.valid.ValidationDelegate
