trouble with "null"-properties

Hello Jasper's!

Since I got the new Version of iReport , I have always troubles when I open an existing and saved Report, wich worked without any problems. After opening, some of the properties have "null"-values, which makes, that the Report is not executable. The Problem is only visible in the XML-view, here an example:

   <staticText>
     <reportElement key="BSP-Ueb" mode="Transparent" x="48" y="40" width="256" height="46" forecolor="#003F87" backcolor="#FFFFFF"/>
     <box>
      <topPen lineWidth="0.0" lineColor="#000000"/>
      <leftPen lineWidth="0.0" lineColor="#000000"/>
      <bottomPen lineWidth="0.0" lineColor="#000000"/>
      <rightPen lineWidth="0.0" lineColor="#000000"/>
     </box>
     <textElement textAlignment="null" rotation="None" lineSpacing="Single">
      <font fontName="GI16-Medium" size="30" isBold="false" isItalic="true" isUnderline="false" isStrikeThrough="false" pdfFontName="GI16MedIta.ttf" pdfEncoding="Cp1252" isPdfEmbedded="true"/>
     </textElement>
     <text><![CDATA[Bausparvertrag]]></text>
    </staticText>
    <image hAlign="null" isUsingCache="false">
     <reportElement key="logo" mode="Opaque" x="349" y="17" width="199" height="83" forecolor="#000000" backcolor="#FFFFFF"/>
     <box>
      <topPen lineWidth="0.0" lineColor="#000000"/>
      <leftPen lineWidth="0.0" lineColor="#000000"/>
      <bottomPen lineWidth="0.0" lineColor="#000000"/>
      <rightPen lineWidth="0.0" lineColor="#000000"/>
     </box>
     <graphicElement fill="Solid"/>
     <imageExpression class="java.io.InputStream"><![CDATA[$F{LOGO}]]></imageExpression>
    </image>

 When I switch back in the Designer-View i get the following error

Error loading the report template
