JBossAS7.1.1でJSF2.1.7とMyfacesCODI1.0.5を使用しています。私<h:commandButton>は働いていません。私は要件を読み、多くのブログの例を通してすべて役に立たなかった。私のfaceletsコードは次のとおりです
<ui:define name="pagecontent">
<h1 class="title ui-widget-header ui-corner-all">Upload Bulk Contact File</h1>
<div class="entry">

関連するCommandButtonがポストバックを開始しない最後の「removeContact」を除いて、すべてのメソッドは正常に機能します。
これはどのように発生し、どうすれば解決できますか？
