[jira] [Updated] (TAP5-1918) RenderInformals mixin doesn't always
work as expected
[ https://issues.apache.org/jira/browse/TAP5-1918?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jochen Kemnade updated TAP5-1918:
---------------------------------
Affects Version/s: 5.4
> RenderInformals mixin doesn't always work as expected
> -----------------------------------------------------
>
> Key: TAP5-1918
> URL: https://issues.apache.org/jira/browse/TAP5-1918
> Project: Tapestry 5
> Issue Type: Bug
> Affects Versions: 5.3.1, 5.3.2, 5.3.3, 5.4
> Reporter: Lance
> Assignee: Kalle Korhonen
> Priority: Minor
>
> The following code:
> <div>
> <t:beaneditform t:id="entity" ... t:mixins="RenderInformals" class="form-horizontal" />
> </div>
> Results in the following HTML:
> <div class="form-horizontal">
> <form ...>
> </form
> </div>
> As you can see, the informal parameter was added to the div instead of the form.
> The current implementation of RenderInformals assumes that a component has populated the MarkupWriter with an element in beginRender() which is not always the case. I think it should be changed to use an afterRender() method and add informals to the current element's last child.
> eg:
> @MixinAfter
> @SupportsInformalParameters
> public class RenderInformals
> {
> @Inject
> private ComponentResources resources;
>
> void afterRender(MarkupWriter writer)
> {
> List<Node> children = writer.getElement().getChildren();
> if (!children.isEmpty()) {
> Element lastChild = (Element) children.get(children.size() - 1);
> for (String name : resources.getInformalParameterNames()) {
> lastChild.attribute(name, resources.getInformalParameter(name, String.class));
> }
> }
> }
> }
