Great, thanks!
I tried it and it mostly works, but there are some problems.
Looks like only one field should be of type titletext, so alias field type should be changed to just text:
Code:
<?xml version="1.0" ?>
<joomfish type="contentelement">
<name>Edocman Document</name>
<author>Tuan Pham Ngoc</author>
<copyright>www.joomdonation.com</copyright>
<version>1.0</version>
<description>Definition for Edocman Autos Documents</description>
<reference>
<table name="edocman_documents">
<field type="referenceid" name="id" translate="0">ID</field>
<field type="titletext" name="title" translate="1">Category Name</field>
<field type="text" name="alias" translate="1">Alias</field>
<field type="htmltext" name="description" translate="1">Description</field>
<field type="htmltext" name="metakey" translate="1">Meta Key</field>
<field type="htmltext" name="metadesc" translate="1">Meta Desc</field>
</table>
</reference>
</joomfish>
<?xml version="1.0" ?>
<joomfish type="contentelement">
