Data Service - only returning 256 chars on text field

Question

Using FlashBuilder Data Services - PHP service all working fine.
Except the service is only returning the first 256 chars of a "text" field of my db table.
The field has more than 256 chars and is marked up via the RTE component
<TEXTFORMAT LEADING="2"><P ALIGN="LEFT"><FONT FACE="Arial" SIZE="14" COLOR="#000000" LETTERSPACING="0" etc...
The generated code looks like(memberservice.php)
public function getAllMember_content() {
        $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename" );       
etc....
Have tried a few conversions on the sql statement to no avail
select *, convert(text,data) as data from members
Any ideas on why this is happening - debugged in charles and its cut off in the response from ZEND/PHP so it in not Flex doing it
this one is killing me :-)

ok solved - kind of
phew - it's the generated service code it appears - not sure why it's working for some and not others! head scratching
this works
public function getAllItems() {
    $this->connect();
    $sql = "SELECT * FROM member_content";
    $result = mysql_query($sql) or die('Query failed: ' . mysql_error());
    return $result;
this does not
public function getAllMember_content() {
        $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename" );       
        $this->throwExceptionOnError();
        mysqli_stmt_execute($stmt);
        $this->throwExceptionOnError();
        $rows = array();
        mysqli_stmt_bind_result($stmt, $row->id, $row->title, $row->topic, $row->type, $row->data, $row->shortdesc, $row->date_created, $row->date_lastmod, $row->rank, $row->createdby, $row->content_source);
        while (mysqli_stmt_fetch($stmt)) {
          $rows[] = $row;
          $row = new stdClass();
          mysqli_stmt_bind_result($stmt, $row->id, $row->title, $row->topic, $row->type, $row->data, $row->shortdesc, $row->date_created, $row->date_lastmod, $row->rank, $row->createdby, $row->content_source);
        mysqli_stmt_free_result($stmt);
        mysqli_close($this->connection);
        return $rows;
thanks all for your help
many thanks
