[1.0] CustomTarget/This EventMask(DirectEvents) in textField/NumberField not work

[sipo]

Only this works(but FireFox looks ugly)(IE looks well)

<ext:BoxItem Flex="1">
                                                            <ext:NumberField ID="txtGoodsId" DataIndex="GoodsId" FieldLabel="xxx" runat="server">
                                                                <DirectEvents>
                                                                    <Change OnEvent="TxtGoodsIdChanged">
                                                                        <EventMask ShowMask="true" Target="Parent" />
                                                                    </Change>
                                                                </DirectEvents>
                                                            </ext:NumberField>
                                                        </ext:BoxItem>

<EventMask ShowMask="true" Target="This" />
<EventMask ShowMask="true" Target="CustomTarget" CustomTarget="txtGoodsId" />
<EventMask ShowMask="true"  Target="CustomTarget" CustomTarget="#{txtGoodsId}" />
<EventMask ShowMask="true"  Target="CustomTarget" CustomTarget="={#{txtGoodsId}}" />
<EventMask ShowMask="true"  Target="CustomTarget" CustomTarget="={#{txtGoodsId}.el}" />
