UI: SBO changing item number?

Hi all,

when adding a new button to an existing form via xml I am receiving a strange result. While the same xml used to add an item with item uid "XXX_TST", now I get an item with uid "1000001". Does anyone know what causes SAP to replace the uid I am passing via xml with an internal uid? As I said, it has been working before and now it is not.

TIA Lutz Morrien

I am using the following xml:

<?xml version="1.0" encoding="utf-8" ?>

<Application>

<forms>

<action type="update">

<form uid="">

<datasources>

<dbdatasources>

</dbdatasources>

</datasources>

<items>

<action type="add">

<Item type="4" left="490" width="60" top="80" height="19" visible="1" enabled="1" form_pane="0"

to_pane="0" disp_desc="1" right_just="0" description="" uid="XXX_TST">

<Specific caption="TEST" />

</Item>

</action>

</items>

</form>

</action>

</forms>

</Application>
