Stéfane Fermigier updated NXP-4934:
-----------------------------------
Component/s: Layouts / Widgets
> Add a generic way to declare validators on builtin widget types
> ---------------------------------------------------------------
>
> Key: NXP-4934
> URL: https://jira.nuxeo.org/browse/NXP-4934
> Project: Nuxeo Enterprise Platform
> Issue Type: Sub-task
> Components: Layouts / Widgets
> Reporter: Anahide Tchertchian
>
> Most of standard widget types are using standard JSF components, that accept
> standard validators. There are two ways to declare a validator on a JSF
> component:
> - use the "validator" property to declare a method binding that will perform
> the
> check and throw a ValidatorException error if validation fails. This is
> already
> available.
> - add a tag inside the component to declare another validator. For instance:
> <h:inputText value="#{field_0}">
> <f:validateLongRange minimum="1"/>
> </h:inputText>
> The "f:validateLongRange" is a standard validator. The "f:validator" tag also
> makes
> it possible to declare a validator by id.
> Custom validators can also be added to the framework. For instance, ui-web
> defines
> validators "nxu:validateFileSize" and "nxu:validateFileMimetype" that can be
> used
> inside the "nxu:inputFile" tag.
> As these tags all accept specific attributes, maybe a generic way to declare
> them on
> the resulting component would be needed.
> Another idea would consist in defining validation rules on the layout, so
> that condi-
> tions can be easily expressed in a el-like language, with some variables
> exposed (to
> define.
> Syntax is still to discuss.
