Hi Embedded wizard team.


I recently migrated from v9.30 to v11.0.

After the migration, there was a partial problem.

I am attaching two files for my question.

Please download using the below link.



The ew slot method.chora file is the chora code.

The Page.c is the generated code based on the above chora code.

The chora code matches the PageOperationWithoutJob_CloseBackupDataManager function at line 34660 in the page.c file.

Let's compare the files generated in v9.30 with those generated in v11.0.

In v11.0 the curly braces are omitted.

In my execution environment, omitting the curly braces is causing the problem.

Below is the gdb log of the code generated in v11.0.

In line.34667, the condition of the if statement is false.

So I was expecting to go to the else statement. (Page.c 34740)

However, unexpectedly, it moves to line.34842 and the function ends.

Breakpoint 1, PageOperationWithoutJob_CloseBackupDataManager (_this=0x3e8f300 <EwMemory+61860456>,
    sender=0x3e7b6d0 <EwMemory+61779512>) at ../GeneratedCode/Page.c:34662
warning: Source file is more recent than executable.
34662   {

34667     ApplicationDeviceClass_SoundTap( EwGetAutoObject( &ApplicationDevice, ApplicationDeviceClass ));
(gdb) n
34662   {
(gdb) n
34667     ApplicationDeviceClass_SoundTap( EwGetAutoObject( &ApplicationDevice, ApplicationDeviceClass ));
(gdb) n
34669     no_tools = ApplicationDeviceClass_GetRegtoolsLen( EwGetAutoObject( &ApplicationDevice,
(gdb) n
34673     if ( sender == ((XObject)&_this->BackupDataManager->OK ))
(gdb) n
34669     no_tools = ApplicationDeviceClass_GetRegtoolsLen( EwGetAutoObject( &ApplicationDevice,
(gdb) n
34673     if ( sender == ((XObject)&_this->BackupDataManager->OK ))
(gdb) n
34675       CoreGroup_OnSetEnabled((CoreGroup)&_this->BackupDataManager->OK, 0 );
(gdb) n
34677       if ( _this->BackupDataManager->Timer500ms.Enabled == 1 )
(gdb) n
34842   }

I can't understand why this is happening.

Can you give me some advice or tips?

I seem to have found the cause of the problem.

Please see the post in the link below.


In EW v11.0, as the curly braces were omitted, the if, else pair was corrupted against my intention.

In chora code, if/else pair is ...

     if (BackupDataManager.Timer500ms.Enabled == true)


But In generated code, if/else pair is ...

     if ( ApplicationDeviceClass_GetTdxToolConn( EwGetAutoObject( &ApplicationDevice, ApplicationDeviceClass ), tdx ) == 1 )


This affects the overall part of my code. so I can't trust the generated code.

Is there any way to solve it?

Checked the EW 11.01 update.

Hello Hantas,

is the issue solved with 11.00.01?

Best regards
