I have implemented an <xxx:ifErrorExists> and <xxx:ifErrorMissing> tag. Here's the doc
of these tags:
ifErrorExists - tests if a specific error exists, for a specific property
Executes its body if a specific error is found. If name is not specified, the tag
checks if one or more
errors exist for the specified property. If name is specified, then the tag checks
that the specific
error exists for the specified property. If not specified, the property defaults to
the "global"
property, i.e., the tag searches for global errors, not associated with any property.
Attribute Description
Should be omitted in most cases. Name of the request scope bean under
which a String[]
errorsName object has possibly been stored. [The value of the
org.apache.struts.Action.ERROR_KEY
constant string].
name Name of the specific error to test.
property Name of the property the error is associated with.
ifErrorMissing - tests if a specific error exists
Executes its body if a specific error is not found.If name is not specified, the tag
checks if one or
more errors exist for the specified property. If name is specified, then the tag
checks that the specific
error exists for the specified property. If not specified, the property defaults to
the "global"
property, i.e., the tag searches for global errors, not associated with any property.
Attribute Description
Should be omitted in most cases. Name of the request scope bean under
which a String[]
errorsName object has possibly been stored. [The value of the
org.apache.struts.Action.ERROR_KEY
constant string].
name Name of the specific error to test.
property Name of the property the error is associated with.
This allows you to put an image or a text behind a form field if there is one or more
errors associated
with this field.
I would of course be honored if these tags were put in the struts distribution.
The code of these tags is trivial, but I can mail it to you if you want.
