Wrong values updating datatable with draggable rows

[LPV]

When using a datatable where the rows are text after changing rows order the values are updated correctly.

Example:

Code: Select all

<p:dataTable id="dt_list" value="#{bean.selectedAt}" var="at" draggableRows="true" rowIndexVar="row">
    <p:ajax event="rowReorder" listener="#{bean.onRowReorder}" />
      <p:column>
         <h:outputText value="#{at.lk_name_at}"/>
        </p:column>
         <p:column>
            <h:outputText value="#{at.lk_number_at}"/>
        </p:column>
     </p:dataTable>

But when the rows have input fields the values are not updated correctly. The list in the backing bean gets all mixed up.

Example:

Code: Select all

<p:dataTable id="dt_list" value="#{bean.selectedAt}" var="at" draggableRows="true" rowIndexVar="row">
    <p:ajax event="rowReorder" listener="#{bean.onRowReorder}" />
    <p:column>
      <p:inputText id="lk_name_at" value="#{at.lk_name_at}"/>
    </p:column>
     <p:column>
       <p:inputText id="lk_number_at" value="#{at.lk_number_at}"/>
     </p:column>
</p:dataTable>

Thanks

I am facing similar issue. the problem after re-ordering is that the input text still contains old vale even after re-order. for example -

suppose id is outputtextand name field is inputtext -

Sample datatable before reordering:

--------------
|id | name |
--------------
| 1 | Data 1 |
| 2 | Data 2 |
| 3 | Data 3 |
| 4 | Data 4 |
--------------
and after reordering (moving 1-st row to 3-rd):

--------------
|id | name |
--------------
| 2 | Data 1 |
| 3 | Data 2 |
| 1 | Data 3 |
| 4 | Data 4 |
--------------

i.e. instead of having Data 1 in third row it still remains into the first row.

Do let me know if there is any workaround. i am using primefaces 6.0 version.

I have the same issue using Primefaces 6.2. My model object has a boolean value, which can be updated by a checkbox in the datatable. If I reorder the list items, then the checkboxes will have the same values as before the reordering, however it should obviously follow the reorder. The worse thing is that it really switches the boolean values in the backing bean, so it is not just displays wrongly, but it does a wrong update.
