Multiple calls of remote datas when using a template

[Laurent]

Hi,

I am using a list view with remote data binding and a template:

<ejs-listview id="userList"

                          headerTitle="User List"

                          showHeader="false"

                          template="#listTemplate"

                          actionComplete="onUserDataBound">

                <e-data-manager url="/ListView/initialData" adaptor="UrlAdaptor" offline="true"></e-data-manager>

                          <e-listview-fieldsettings text="UserName" id="UserId" />

            </ejs-listview>

<script id="listTemplate" type="text/x-jsrender">

    <div class="e-list-wrapper">

        <span class='e-list-content'>${UserName}</span>

    </div>

</script>

When debugging with a break point in the controller method, the method is called :

• Once if not using the template property of the listview
• twice if using the template property
• three times if setting offline property of the data manager to true.

So I have performance issue due to this behaviour. How can I manage to have only one controller call when using the template method?

Regards,

Laurent
