Question

我有习惯,定义如下:

<wicket:panel>
    <div>
        <form wicket:id="form" class="wizard">
            <span class="wizardoverview" wicket:id="overview"/>

            <div class="wizardheader" wicket:id="header"/>
            <div wicket:id="view" class="wizardpage"/>
            <span wicket:id="feedback"/>

            <div class="buttons">
                <span wicket:id="buttons"/>
            </div>
        </form>
    </div>
</wicket:panel>

The wizardpage is in this case a Panel with its own form. This form contains a new Panel, which in turn contains a GridView. The GridView contains a set of Panels, which each contain a FormComponentFeedbackBorder, which in turn contains input TextFields.

!!

因此,我们这样做:

Wizard->

When TextField fails validation, no feedback is rendered at all. If I add a FeedbackPanel to the GridContainingPanel the error messages are rendered, but FormComponentFeedbackBorder renders nothing.

谁会错?

I had a similar problem with a ListView instead of GridView, but that problem was resolved when I set listView.setReuseItems(true);

GridView是否有类似的情况? 这一问题是否有不同的解决办法?

Answer 1

这是:

gridView.setItemReuseStrategy(new ReuseIfModelsEqualStrategy());

这个问题已经解决。

谢。
