JSF中未调用action方法

问题描述

这是我的相位监听器

public class AdminPhaseListener implements PhaseListener {

private static final long serialVersionUID = -1161541721597667238L;

    public void afterPhase(PhaseEvent e) {
        System.out.println("after Phase " + e.getPhaseId());
    }

    public void beforePhase(PhaseEvent e) {
        System.out.println("before Phase " + e.getPhaseId());
        if(e.getPhaseId()== PhaseId.RESTORE_VIEW)
        {

        }

    }

    public PhaseId getPhaseId() {
        return PhaseId.ANY_PHASE;
    }
}

在我的页面中单击命令按钮时，我调用一个动作方法并进行一些处理，但是根本没有调用该动作方法，但是在服务器日志中，我可以看到PhaseListener为所有对象打印的消息.阶段.

如果我的视图未更改，它将在RESTORE_VIEW阶段结束后停止吗?

有什么想法吗?

添加有关如何显示命令按钮的代码:

<table width="100%">
    <h:column rendered="#{adminBean.displayResultsSize > 0}">

        <tr>
            <td colspan="14" height="5" nowrap="nowrap" class="WhiteRow"></td>
        </tr>
        <tr>
            <td colspan="14" height="1" nowrap="nowrap" align="center"
                bgcolor="#999999"></td>

        </tr>
        <h:inputHidden  id="removeUserId" value="#{adminBean.removeUserId}"/>
        <h:inputHidden  id="removeIBD" value="#{adminBean.removeIBD}"/>
        <h:inputHidden  id="removeAPA" value="#{adminBean.removeAPA}"/>
        <tr>
            <td colspan="14" height="30" nowrap="nowrap"
                class="FilterColumnGrayHeader" align="center">&nbsp;&nbsp;&nbsp;
            <input type="button" disabled="disabled" id="button_edit"
                value="Edit Details" class="disabledfield"
                onclick="populateEditRow();">
            </input> <h:commandButton type="submit" class="disabledfield" immediate="true"
                id="button_remove" value="Remove" onclick="populateRemoveRow();" action="#{adminBean.remove}">
            </h:commandButton> &#160;

            </td>
        </tr>
        <tr bgcolor="#000000">
            <td colspan="14" height="1" nowrap="nowrap" align="center"
                bgcolor="#999999"></td>
        </tr>
        <tr>
            <td height="10"></td>
        </tr>
    </h:column>
</table>

解决方案

我引用的是:

另一个原因可能是您没有运行您认为正在运行的代码.

This is my Phase Listener

public class AdminPhaseListener implements PhaseListener {

private static final long serialVersionUID = -1161541721597667238L;

    public void afterPhase(PhaseEvent e) {
        System.out.println("after Phase " + e.getPhaseId());
    }

    public void beforePhase(PhaseEvent e) {
        System.out.println("before Phase " + e.getPhaseId());
        if(e.getPhaseId()== PhaseId.RESTORE_VIEW)
        {

        }

    }

    public PhaseId getPhaseId() {
        return PhaseId.ANY_PHASE;
    }
}

On click of a Command Button in my page, i call an action method and do some processing but the action method is not called at all, but in the server log , i could see the messages printed by my PhaseListener for all the Phases.

If my view was not changed, It would have stopped after the RESTORE_VIEW Phase right?

any thoughts?

Adding the code for How I display the Command Button :

<table width="100%">
    <h:column rendered="#{adminBean.displayResultsSize > 0}">

        <tr>
            <td colspan="14" height="5" nowrap="nowrap" class="WhiteRow"></td>
        </tr>
        <tr>
            <td colspan="14" height="1" nowrap="nowrap" align="center"
                bgcolor="#999999"></td>

        </tr>
        <h:inputHidden  id="removeUserId" value="#{adminBean.removeUserId}"/>
        <h:inputHidden  id="removeIBD" value="#{adminBean.removeIBD}"/>
        <h:inputHidden  id="removeAPA" value="#{adminBean.removeAPA}"/>
        <tr>
            <td colspan="14" height="30" nowrap="nowrap"
                class="FilterColumnGrayHeader" align="center">&nbsp;&nbsp;&nbsp;
            <input type="button" disabled="disabled" id="button_edit"
                value="Edit Details" class="disabledfield"
                onclick="populateEditRow();">
            </input> <h:commandButton type="submit" class="disabledfield" immediate="true"
                id="button_remove" value="Remove" onclick="populateRemoveRow();" action="#{adminBean.remove}">
            </h:commandButton> &#160;

            </td>
        </tr>
        <tr bgcolor="#000000">
            <td colspan="14" height="1" nowrap="nowrap" align="center"
                bgcolor="#999999"></td>
        </tr>
        <tr>
            <td height="10"></td>
        </tr>
    </h:column>
</table>

I'm citing from this answer:

Another cause can be that you're not running the code you think you're running.
