Use image instead of submitbutton

Question

Hello,
I try to use an image instead of the <submitButton> Tag supported by UIX. I have a form with BC4J Table and tableSelection in it. Now I want to submit this form instead of the update or delete Buttons generated by JDeveloper with an image.
The selected key does not come with.
<form name="viewForm" method="POST" >
<contents>
<tableLayout>
<contents> <bc4j:viewObjectScope name="UserView1" >
<contents>
<bc4j:table name="viewTable" width="800" alternateText="No rows found">
<tableSelection>
<singleSelection selectedIndex="0">
<contents>
<text text="    "/>
<ui:image source="images/adddocumenttolist_enabled.gif" ctrl:event="create" shortDesc="add" /> <ui:image source="images/edit_big.gif" destination="#" onClick="submitForm('viewForm',1,{'event':'update'});return false" shortDesc="Bearbeiten" />
<ui:image source="images/delete_L.gif?key=" ctrl:event="delete" shortDesc="Loeschen"/>
</contents>
</singleSelection>
</tableSelection>
<bc4j:keyStamp>
<bc4j:rowKey name="key" />
</bc4j:keyStamp>
<contents>
Replace one of the Image-Tags with <submitButton ctrl:event="..." text="..."/> works???

Hello,
I tried adding
<formValue name="event"/> and that worked for me. This adds this html:
<input type="hidden" name="event">
The submit button does this for you automatically.
