List - Growing and GrowingThreshold

Hi,

I am trying to use List's growing and growingThreshold and it doesnt seem to work for me on WEBIDE Fiori application using a master detail template.

I have a link that I use to return service request collection. This collection is too big and in the browser I use -

../ZOPTIMUS_SRV/ServiceRequestCollection/?sap-ds-debug=true&

$inlinecount=allpages&$top=50

Now in my code I try to use Growing and GrowingThreshold to achieve this. But this does not work.. Any idea?

<content>

   <List

id="list"

  select="onSelect"

mode="{device>/listMode}"

noDataText="{i18n>masterListNoDataText}"

growing="true"

growingThreshold="4"

growingScrollToLoad="false"

  items="{/ServiceRequestCollection}">

<customData

id="customData1">

<core:CustomData

id="coreCustomData1"

key="sapDtResourcePath"

value="ServiceRequestCollection">

</core:CustomData>

</customData>

<items

id="masterList">

<ObjectListItem

id="mainListItem"

press="onSelect"

type="{device>/listItemType}"

counter="0"

                                                                                          title="{ServiceRequestId}"

                                                                                          number="{MasterContract}"

                                                                                          numberUnit="{Price}"

                        markFavorite="false"

markFlagged="false"

showMarkers="false">

<customData

id="customData2">

<core:CustomData

                                id="coreCustomData2"

key="sapDtResourcePath"

                                                                                                                        value="ServiceRequestCollection">

</core:CustomData>

</customData>

<core:ExtensionPoint

name="extListItemInfo"/>

</ObjectListItem>

</items>
