walk method called manytimes for the first time

[anisj1m]

Hi,

I extended ExtendedDataModel in order to face to the problem of the lazy pagination, but I am having this problem : I am loding the data inside the method walk, and for the first time when I click on search the walk method is called 3 times, but after that it is called just once:

this is the method walk

@Override
    public void walk(FacesContext fc, DataVisitor dv, Range range, Object o) {
        SequenceRange sr = (SequenceRange) range;
        int firstRow = sr.getFirstRow();
        int numbersRows = sr.getRows();
        Manager manager = new Manager();
       data = manager.loaddata();
        for (Declaration dec : data) {
                  try {
                            wrappedData.put(dec.getId(), dec);
                                        dv.process(fc,dec.getId(), o);
                              } catch (IOException e) {
                                        e.printStackTrace();
                              }
                    }
    }

and this is the method getRowData :

 @Override
    public Declaration getRowData() {

        //return data.get(rowKey);
              return wrappedData.get(rowKey);
    }

Thanks in advance

any idea please?

here how i use the dataTable :

<h:form>
<rich:dataTable id="pData" value="#{bean.model}" var="X" rows="10">
</rich:dataTable>

<a4j:commandButton value="Search 4aj" reRender="pData"></a4j:commandButton>
</h:form>

Finaly i found the problem;

I had to create a new form for the button, so the a4j will be submitted and the dataTable will be rendered.

<h:form>
<rich:dataTable id="pData" value="#{bean.model}" var="X" rows="10">
</rich:dataTable>
</h:form>

<a4j:form>
<a4j:commandButton value="Search 4aj" reRender="pData"></a4j:commandButton>
</a4j:form>
