所以我最初有一个
<h:selectBooleanCheckbox value="#salesExpenseController.addSalesExpense.fixed}" >
<h:ajax event="change" listener="#{salesExpenseController.checkFixed()}" render = "addBidPrice addBidTotal" />
</h:selectBooleanCheckbox>
听众功能：
public String checkFixed() {
if (this.getAddSalesExpense().getFixed()) {
if (this.subOperation.equals(_add)) {
getAddSalesExpense().setBidPrice(BigDecimal.ZERO);
}
if (this.subOperation.equals(_edit)) {
getEditSalesExpense().setBidPrice(BigDecimal.ZERO);
}
} else {
if (this.subOperation.equals(_add)) {
getAddSalesExpense().setBidTotal(BigDecimal.ZERO);
}
if (this.subOperation.equals(_edit)) {
getEditSalesExpense().setBidTotal(BigDecimal.ZERO);
}
}
return _viewTimberSale;
}
每当我点击我的复选框时，该表单中的所有其他命令链接都不起作用。我在checkFixed（）中放置了一个System.out.println（），并且ajax请求没有到达该函数或发出任何错误，表现得一无所获。
我通过将复选框更改为：
来解决此问题<h:selectBooleanCheckbox value="#{salesExpenseController.addSalesExpense.fixed}" >
<p:ajax event="change" listener="#{salesExpenseController.checkFixed()}" update = "addBidPrice addBidTotal" />
</h:selectBooleanCheckbox>
一切都运转正常，应该如何。
什么是可能的解释？
这是表单的错误部分，我无法发布整个表单超过30,000个字符：

答案 0 :(得分：0)
我不知道primeFaces以及它如何执行ajax命令，但标准的ajax监听器方法不应该返回任何对象。但是这样的事情：
public final void checkFixed(AjaxBehaviorEvent event){
.....
}
你可以这样使用它：
listener="#{salesExpenseController.checkFixed}"
因此，如果您的视图因任何Java异常（如未找到methode等）而抛出任何JS错误，则此JS错误将分解所有commandLinks /按钮等。也许primeFaces接受像你这样的监听器的方法，所以当你使用primefaces ajax命令时你不会得到任何错误。
