Add component on a button click

[Joe Jose]

Hi,

I have been trying to add componenets checkbox and an input text box since last week. I was using selectmany check box ,that didn't work out. Now when I went through the forum, I found that I can use selectBooleanCheckbox for dynamically adding. Now, when I press the button for the first time I got a checkbox and an input text. But when I press the button second time, nothing happens instead of adding one more checkbox and input text.

I am confused now. I am putting my code here, please anyone direct me from here ?

jsp:

    
<h:panelGroup binding="#{CreateQuoteBean.group}">
</h:panelGroup>
<h:commandButton id="addAdhocs" action="#{CreateQuoteBean.addAdhocs}" 
value="Add" styleClass="focusButton" />

bean:

    
public String addAdhocs() {
         
        FacesContext context = FacesContext.getCurrentInstance();
        HtmlSelectBooleanCheckbox cb = new HtmlSelectBooleanCheckbox();
        int id = 0;
        cb.setId("d" + id);  
        String bind = "#{dynamic.entered[" + id + "]}";
        Application app = context.getApplication();
        cb.setValueBinding("value", app.createValueBinding(bind));
        group.getChildren().add(cb);
 
 
        HtmlInputText input = new HtmlInputText();
        group.getChildren().add(input);    
        id++;
        return "addAdhoc";
     }

More clearly, if I press the Add button two time, I need to get 2 checkboxes and input boxes.
Bauke gave me initial idea, but still am confused.
Please help me.

Thanks,
Joe.

I have suggested you to use DTO's instead.

Hi,

I have tried with DTO. But the added values doesn't diplay in datatable.

What I am trying to do is, enter value through input text and display it in a datatable.

Here is my code :

jsp:

<h:panelGrid id="a1" columns="6">
<h:outputLabel for="task" value="#{msg.task}" />
<f:verbatim>          </f:verbatim>
<h:inputText id="task" value="#{CreateQuoteBean.task}"/>
<h:outputLabel for="tskExtQt" value="#{msg.tskExtQt}" />
<f:verbatim>          </f:verbatim>
<h:inputText id="tskExtQuote" value="#{CreateQuoteBean.tskExtQuote}"/>
</h:panelGrid>

<h:commandButton id="addAdhocs" action="#{CreateQuoteBean.addAdhocs}"
value="Add" styleClass="focusButton" />

<h:dataTable value="#{CreateQuoteBean.taskDataList}">
<h:column>
<h:outputText id ="tk" value="#{TaskSelected.taskData}" />
<h:message for="tk"/>
</h:column>
<h:column>
<h:outputText id="td" value="#{TaskSelected.taskQt}" />
</h:column>
</h:dataTable> [/CODE]

bean:

    
public String addAdhocs() {
         
        TaskSelected selected = new TaskSelected();
        selected.setTaskSelected(new ArrayList());
        selected.setSelectTaskList(getSelectTaskList());
        selected.setTaskData(getTask());
        selected.setTaskQt(getTskExtQuote());
        Logger.getLog().debug("TaskData : "+selected.getTaskData());
        Logger.getLog().debug("TaskQt : "+selected.getTaskQt());
        taskDataList.add(selected);
        Logger.getLog().debug("taskDataList size : "+taskDataList.size());
        return "addAdhoc";
     }

I don't understand why the values not setting in output text. Please help me.

Thanks,
Joe.

I got it. I hadn't given var attribute in datatable tag.

Thank you very much Bauke.
