form submit doesnt work when using an encoder

[hese]

hi

I have a form in which I use a grid with an encoder.  Strangely when I
include the encoder attribute in the grid component onSubmit() or
onSuccessFrom...() dont get called.  When I remove the the encoder attribute
they are called.


Any ideas???

TML

 <form t:type="form" t:id="upload" t:context="id">
<t:errors/>
  <t:upload t:id="file" class="text medium" />
  <t:submit class="button" value="${message:button.make}" t:id="make" />
  <t:submit class="button" value="${message:button.upload}" t:id="save"/>

<table>
  <t:grid t:id="tags1" t:source="tagRows" t:row="tagRow"
t:encoder="tagRowEncoder" t:rowclass="prop:evenodd.next">
</t:grid>
</table>

</form>


JAVA

@Property
        private TagRowEncoder tagRowEncoder;

void onPrepare() {
                tagRowEncoder = new TagRowEncoder();
        }


private class TagRowEncoder implements ValueEncoder<TagRow> {

        @Override
        public String toClient(TagRow value) {
                        Long key = value.getKey();
                        return key.toString();
                }

        @Override
                public TagRow toValue(String keyAsString) {
                        long key = Common.toLong(keyAsString);
                        for (TagRow holder : tagRows) {
                                if (holder.getKey() == key) {
                                        return holder;
                                }
                        }
                        throw new IllegalArgumentException("Received key \"" + 
key
                                        + "\" which has no counterpart in this 
collection: " + tagRows);
                }
}
