Hello,

I found out a bug when we fetch results using a joined query and boost.tuple. Although results from the backend are correct but the Dbo::collection shows weird results. When I iterated though 13 items, the results were not unique and the results were duplicates.

Example:¶

Expected Result Keys:¶

DosPuzzle

LogDebugLevel

LogErrorLevel

LogInfoLevel

LogSecureLevel

LogWarnLevel

Actual Result Keys:¶

LogDebugLevel

DosPuzzle

DosPuzzle

LogDebugLevel

LogDebugLevel

LogDebugLevel

LogDebugLevel

Source Code¶

The source code is in my forked repository of Wt in github.

https://github.com/SaiFi0102/wt/tree/Saif, the branch is "Saif"

Starting from file https://github.com/SaiFi0102/wt/blob/Saif/src/MM/Main.cpp, line 68

Config = new Configurations;

try
{
       //Config->Uninstall();
       Config->Install();
       Config->FetchAll();
}

Config->Install(): Inserts test data to the database(sqlite3(":memory:"))

Config->FetchAll(): Queries and fetches data using the joined queries and prints the key "Name" of each to std::cerr

Please check this.

Thank you.
