Hi,
The question of Roman helped a little bit to solve my problem.
Un/marshalling workes fine now. However when I unmarshall my HashMap the value
and the key are both of type org.exolab.castor.mapping.MapItem. The problem is
that I can't cast the value back to the original type. Can somebody give me a
hint what I need to do.
<class name="GUI.SaveData">
<map-to xml="SavaData"/>
<field name="proj" />
<field name="graphicData" collection="map" container="false">
<bind-xml name="graphData" node="element" >
<class name="org.exolab.castor.mapping.MapItem">
<field name="key" type="java.lang.Object">
<bind-xml name="id" node="attribute" location="param"/>
</field>
<field name="value" type="GUI.ImageAndPositionData">
<bind-xml name="value" node="attribute" location="param"/>
</field>
</class>
</bind-xml>
</field>
</class>
graphicData is my HashMap.
