Class TOraNumberField not found. Ignore the error and continue?...

[brad]

I wish to use TOraNumberField field type. Table declaration has Oracle field type "NUMBER" (or "NUMBER(16)" for example). I have set OraSession.Options: EnableIntegers=true, EnableNumbers=true.
All ok, compiled and working...

But! After the C++Builder project just first reloaded into IDE - error occured (during forms loading):
"Class TOraNumberField not found. Ignore the error and continue?"
"Ignoring" will eliminate TOraNumber-field declaration;
in case of "cancelling" - form will not displayed (until this TOraNumberField will be deleted), but project compiled successfully....
All paths to ODAC-libs a specified correctly.

Is there any solution?
I won't use TIntegerField and TFloatField.

ps. using C++Builder 6, Oracle 9.2.0.7

Sorry, we cannot reproduce your problem. We need more detailed description i.e. your ODAC version, complete sample to demonstrate your problem and script to create server objects.
Please, send a message to our ODAC support e-mail address.

I tried to use ODAC 5.55.122, 5.55.124 - both has the same problem.

I think that problem is easy reproducable:
just now i created the new (empty) project, drops OraSession1 (TOraSession) + OraTable1 (TOraTable) + DataSource1 (TDataSource or TOraDataSource). Set OraTable1.TableName="SYSTEM.HELP" ('system' table in Oracle 9.2.0.7).

Default project directories settings (not changed):
Include path = "..\Lib\ODAC555124\Source\CBuilder6\Odac\Include;..\;ODAC_Test;$(BCB)\include;$(BCB)\include\vcl"
Library path = "..\Lib\ODAC555124\Source\CBuilder6\Odac\Include;..\;ODAC_Test;$(BCB)\Projects\Lib;$(BCB)\lib\obj;$(BCB)\lib"

1) First, OraSession1.Options not changed: EnableIntegers=true, EnableNumbers=false (as by default). Fields editor was called for OraTable1, added field "SEQ" (from table "SYSTEM.HELP", type is "NUMBER") - the delphi-type is "TFloatField", as expected. Project compiled, closed & reopened successfully, always.

2) Set OraSession1.Options.EnableNumbers=true. Field "SEQ" deleted and created newly. Now the type is "TOraNumberField", as expected (due to EnableNumbers=true). Project compiled successfully, then closed... But does not open! Error message: "Class TOraNumberField not found. Ignore the error and continue? NOTE: Ugnoring the error may cause components to be deleted or property values to be lost. [Ignore] [Cancel] [Ignore All]". After pressing [Cancel] button the second message box appears: "Error creating form: Class TOraNumberField not found [Ok]". Pressing [Ok], project loaded, but his form (with database-aware components) not shown - i.e. code editor available, but visual editor not. Then, i try to compile the project - this is done successfully, project compiled!!! Full project rebuild works also. And program works as expected.
Problem only that class TOraNumberField load failed at design-time (and form designer does not work).


Setting project path's to:
Include path = "$(BCB)\Include;$(BCB)\Include\Vcl;..\Lib\ODAC555124\Source\CBuilder6\Odac\Include;..\Lib\ODAC555124\Source\CBuilder6\Odac\CRGrid;..\Lib\ODAC555124\Source"
Library path = "$(BCB)\Lib;$(BCB)\Lib\Obj;..\Lib\ODAC555124\Source\CBuilder6\Odac\Lib;..\Lib\ODAC555124\Source\CBuilder6\Odac\Dcu;..\Lib\ODAC555124\Source\CBuilder6\Odac\CRGrid;..\Lib\ODAC555124\Source"
- does not help to solve a problem.

We couldn't reproduce your problem.
Try to unistall and install ODAC again, if the problem persists please send
us sample project to demonstrate your problem.
Send message to ODAC support address.
