    <p>Are you using Filter parameters? I've also created custom transport filters, but never encountered this error. Here's an example do-nothing log filter...</p> <pre><code>unit LogFilter; interface uses SysUtils, DBXPlatform, DBXTransport; type TLogFilter = class(TTransportFilter) public constructor Create; override; destructor Destroy; override; function ProcessInput(const Data: TBytes): TBytes; override; function ProcessOutput(const Data: TBytes): TBytes; override; function Id: UnicodeString; override; end; const LogFilterName = 'Log'; implementation uses CodeSiteLogging; constructor TLogFilter.Create; begin inherited Create; CodeSite.Send(csmBlue,'TLogFilter.Create'); end; destructor TLogFilter.Destroy; begin CodeSite.Send(csmBlue,'TLogFilter.Destroy'); inherited Destroy; end; function TLogFilter.ProcessInput(const Data: TBytes): TBytes; begin Result := Data; CodeSite.Send(csmYellow, 'ProcessInput ' + IntToStr(Length(Data)), TEncoding.ASCII.GetString(Data)); end; function TLogFilter.ProcessOutput(const Data: TBytes): TBytes; begin Result := Data; CodeSite.Send(csmOrange, 'ProcessOutput ' + IntToStr(Length(Data)), TEncoding.ASCII.GetString(Data)); end; function TLogFilter.Id: UnicodeString; begin Result := LogFilterName; end; initialization TTransportFilterFactory.RegisterFilter(LogFilterName, TLogFilter); finalization TTransportFilterFactory.UnregisterFilter(LogFilterName); end. </code></pre> <p>This one works just fine for me (one of the example from my upcoming Delphi XE DataSnap Development Essentials courseware manual).</p> <p>Groetjes, Bob Swart</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
