[seam-issues] [JBoss JIRA] Closed: (JBSEAM-3251) ValidateAllRendererBase not robust enough for dynamic components

ValidateAllRendererBase not robust enough for dynamic components ---------------------------------------------------------------- Key: JBSEAM-3251 URL: https://issues.jboss.org/browse/JBSEAM-3251 Project: Seam Issue Type: Bug Components: JSF Controls Affects Versions: 2.0.2.SP1, 2.0.3.CR1, 2.1.0.A1 Environment: Any Reporter: Richard Kennard Assignee: Marek Novotny Priority: Minor Fix For: 2.2.1.CR3 Attachments: ValidateAllRendererBase.java Original Estimate: 30 minutes Remaining Estimate: 30 minutes org.jboss.seam.ui.renderkit.ValidateAllRendererBase has two minor problems (with easy fixes) that stop it working with highly dynamic components: 1. doEncodeChildren attaches its ModelValidators before calling renderChildren. This misses any subcomponents the children may themselves dynamically create during their encodeBegin phase. Moving renderChildren down fixes this 2. A ModelValidator is only attached if the component has no existing Validators. This seems a bit of a blunt instrument. Presumably the idea is to stop attaching multiple ModelValidators. If the component happens to have, say, a LengthValidator that shouldn't stop ModelValidator entirely. I have attached an updated ValidateAllRendererBase. It does not break any existing unit tests. Disclaimer: my vested interest in this is because of Metawidget (http://www.metawidget.org).
