This last night I have been doing some tests and this is what I have discovered.
In Label: File name the Original es empty.
This is the reason why the title in joomfish hikashop files listing is empty (I think).
Then I did some tests with the contentelement hikashop_file.xml.
This is the original code
<?xml version="1.0" ?>
<joomfish type="contentelement">
<name>Hikashop Files</name>
<author>Hikari Software</author>
<version>1.0.0</version>
<description>Definition of files/images for the hikashop component</description>
<copyright>Copyright (C) 2010 Hikari Software SARL - All rights reserved.</copyright>
<reference type="content">
<table name="hikashop_file">
<field type="referenceid" name="file_id" translate="0">ID</field>
<field type="titletext" name="file_name" length="255" maxlength="255" translate="1">File name</field>
<field type="text" name="file_path" length="255" maxlength="255" translate="1">File path</field>
<field type="textarea" name="file_description" rows="10" columns="80" translate="1">File description</field>
</table>
</reference>
<translationfilters>
</translationfilters>
</joomfish>
And this is the code I did.
<?xml version="1.0" ?>
<joomfish type="contentelement">
<name>Hikashop Files</name>
<author>Hikari Software</author>
<version>1.0.0</version>
<description>Definition of files/images for the hikashop component</description>
<copyright>Copyright (C) 2010 Hikari Software SARL - All rights reserved.</copyright>
<reference type="content">
<table name="hikashop_file">
<field type="referenceid" name="file_id" translate="0">ID</field>
<field type="text" name="file_name" length="255" maxlength="255" translate="1">File name</field>
<field type="titletext" name="file_path" length="255" maxlength="255" translate="1">File path</field>
<field type="textarea" name="file_description" rows="10" columns="80" translate="1">File description</field>
</table>
</reference>
<translationfilters>
</translationfilters>
</joomfish>
The result.
Mabe is not the best solution but is enough for me for now.
