The newest version maybe have a bug.

[GoogleCodeExporter]

- ExtPascal: rev.594
- ExtJS: v.3.0
- Compiler: Delphi 7
- OSes: WindowsXP sp2
- WebServer: Apache2
- Mode: FCGI

Today I update to 594,my old version is 586.
After update,my program have two errors.
1.I use 
DataStore : TExtDataJsonStore;
GridTableViewData: TExtGridEditorGridPanel;
to display the data from mysql-5

  DataStore := TFunctions.GetDataStore(MethodURI
(GridTableViewDataLoadData), 'Root', 'Total', sTableId, true, 
ViewDataFieldDefines);

on the procedure GridTableViewDataLoadData,
    Response := '{Total: ' + IntToStr(nDataCount) + ', Root:[' + Records 
+ ']}';

I check it, the Records have datas.
On version 594,the GridTableViewData did not display the record.was empty.

But if I restore to version 584,
my program is work ok.

my program reference ExtentDialer demo.

2.The next error is:
On the version 594, the unit ExtPascalUtils.pas
function BeautifyJS

          repeat
            i := i+1;
            // find multiple statement block end
            if (res[i] = '{') or (res[i] = '}') or (res[i] = ';') then 
backward := true;  //////Please note,this line raise exception
            if inNew and (res[i] = ']') then backward := true;
          until (res[i] = ',') or backward;

about line 541:

After DataStore.Reload(nil),maybe after 60-120 seconds,the program will 
raise exception at line 541.
the exception message is EAccessViolation

But on version 586,not raise exception.

I don't know this is a bug or not,please check.
If I have free time,I will compare the version 594 and 586.

Today I delete the DebugJS define,my program run fine.
I think the BeautifyJS function maybe have a bug.I meet this bug on version 586 
and 
594.

Possibly BeautifyJS function doesn't work with JSON/XML data transfers.
