Mysql select statement where = works and LIKE fails

Question

I am using Flash Builder 4. On the server side I use php and mysql. I created a php dataservice using FB4. My plan had been to allow users to enter a search term and query the database using a "LIKE" statement. FB4 created the php code that I simply modified changing the parameter name. The input parameter is a string.
public function getT_caseByID($searchTerm) {
$stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE (title = ?)");
$this->throwExceptionOnError();
mysqli_stmt_bind_param($stmt, 'i', $searchTerm);
$this->throwExceptionOnError();
mysqli_stmt_execute($stmt);
$this->throwExceptionOnError();
mysqli_stmt_bind_result($stmt, $row->idt_case, $row->title, $row->id_author, $row->comments);
if(mysqli_stmt_fetch($stmt)) {
      return $row;
} else {
      return null;
A look at FB4 shows this code returns data.
This code works fine but if I make the below change it fails, even when I use the wildcard %. the only change is "=" to "LIKE".
public function getT_caseByID($searchTerm) {
$stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE (title LIKE ?)");
$this->throwExceptionOnError();
mysqli_stmt_bind_param($stmt, 'i', $searchTerm);
$this->throwExceptionOnError();
mysqli_stmt_execute($stmt);
$this->throwExceptionOnError();
mysqli_stmt_bind_result($stmt, $row->idt_case, $row->title, $row->id_author, $row->comments);
if(mysqli_stmt_fetch($stmt)) {
     return $row;
} else {
     return null;
A look into FB4 shows "void".
Any help would be appreciated. I am using localhost on Apache Server on a development computer with Windows XP.
