I'm having trouble rendering a button in a table based on Generating shapes based on table rows.

It has worked before but this time the button won't render. The parameter can be set trough the element (table context-menu).

Button:

Protocol parameter:

<Param id="367" snmpSetAndGet="true">
<Name>Orbit</Name>
<Description>Satellite Orbit Position</Description>
<Type>write</Type>
<Interprete>
<RawType>other</RawType>
<Type>string</Type>
<LengthType>next param</LengthType>
</Interprete>
<SNMP>
<Enabled>true</Enabled>
<OID type="complete">1.3.6.1.4.1.27359.12.10.2.1.3.17</OID>
<Type>octetstring</Type>
</SNMP>
<Display>
