Visualizing Validation Errors next to Components that cause them

Hi there,

is there anyway to visualize errors next the components that caused them?
One solution I can think of is actually validating every single one of these components, however it doesn't feel nice.

I am currently using a bespoke sublcass of MAToOneRelationDescription to structure my form into different sections. It is cascading the validation to all these embedded objects.

Any ideas?

Cheers,
Felix

Sure. The default renderer MATableRenderer adds the class '.error' to
the element, so that you can highlight the validation errors using CSS
styles.

I assume that you also want to display the error message somewhere
close-by? In this case you have to implement your own renderer and
assign it to the container description (see the reference to
MATableRenderer).

Cheers,
Lukas

Hi Lukas,

unfortunately the whole case is a bit more difficult because I am using nested components. The situation is visulised in this screenshot:

The trouble is, that the embedded components don't have access to the errors, as the outer component starts calling into the descriptors and inside the validation logic there is no reference to the embedded components, so the errors can't be added to those.

I am a bit lost. Should I perhaps abandon the idea of flattening multiple objects into a single form?

Cheers,
Felix

Personally I've never really used the internal editors.

What I usually do in such situations is to build individual components
(without buttons and validation) for the the different objects and
then present these components from a normal Seaside component.

Another possibility is to build a single flat description consisting
the descriptions of multiple objects. Search the mailing list on how
to build such a composite description. This sometimes works well.
