[英]Primefaces datatable sorting after filtering
I have ap:dataTable which stores the results of a processed form, and I perform the following actions: 我有ap:dataTable,它存储已处理表单的结果,并且执行以下操作:
I have an arraylist for the filtered values, but I am not doing anything to it in the bean. 我有一个用于过滤值的arraylist,但是我在bean中没有对它做任何事情。 On submit, I am calling an actionListener which casts the dataTable to primefaces.components.datatable.DataTable and then calling a resetValue() on it (see code snippet below), before I process the form. 在提交时,我正在调用actionListener,它将数据表转换为primefaces.components.datatable.DataTable,然后在处理表单之前对其调用resetValue()(请参见下面的代码段)。
I've tried multiple ways of resetting, clearing and updating the dataTable, but I'm not able to get around the above issue. 我尝试了多种方法来重置,清除和更新dataTable,但无法解决上述问题。 Just for reference, this is my p:dataTable tag: 仅供参考,这是我的p:dataTable标记:
<p:dataTable
id="resultsDataTable"
rendered="#{entityReportBean.isResultsPopulated}"
var="change"
value="#{entityReportBean.entityChangeDto}"
styleClass="resultsPanel"
rows="100"
paginator="true"
paginatorPosition="top"
paginatorTemplate="#{PreviousPageLink} Previous {CurrentPageReport} Next {NextPageLink}"
filterEvent="enter"
filteredValue="#{entityReportBean.filteredResults}" >
and this is the actionListener: 这是actionListener:
public void onSubmit() {
FacesContext context = FacesContext.getCurrentInstance();
DataTable resultsTable = (DataTable) context.getViewRoot().findComponent("results:resultsDataTable");
resultsTable.resetValue();
...
I am fairly new to JSF/Primefaces so there might be some basic operation I'm unaware of. 我对JSF / Primefaces相当陌生,因此可能有一些我不知道的基本操作。 Any suggestions? 有什么建议么?
So I realized that there was no point trying to do anything in my actionListener as that is not being invoked on sort. 因此,我意识到尝试在我的actionListener中做任何事情都是没有意义的,因为没有按类别进行调用。 So I added an ajax 'sort' event on the dataTable and added a resultsTable.updateValue(entityChangeDto);
因此,我在dataTable上添加了一个resultsTable.updateValue(entityChangeDto);
'事件,并添加了一个resultsTable.updateValue(entityChangeDto);
to the listener. 给听众。 Now all is well. 现在一切都很好。
