YAG - Theme Simpleviewer

Hello!

I've got big troubles with managing Albums/Galleries (especially our customers are very annoyed of some bugs)

1. Often after clicking on an edit Button of a gallery another gallery is chosen
2. Often when i edit the images of a gallery they disappear - we don't know if they are deleted!
3. I also get Deprecated Logs en masse: Tx_Fluid_ViewHelpers_RenderFlashMessagesViewHelper->initialize() - - Tx_Extbase_Core_Bootstrap->callModule#57 // Tx_Extbase_Core_Bootstrap->run#310 // Tx_Extbase_MVC_Web_BackendRequestHandler->handleRequest#247 // Tx_Extbase_MVC_Dispatcher->dispatch#48 // Tx_Yag_Controller_AbstractController->processRequest#82 // Tx_Extbase_MVC_Controller_ActionController->processRequest#137 // Tx_Extbase_MVC_Controller_ActionController->callActionMethod#155 // Tx_Fluid_View_AbstractTemplateView->render#255 // Tx_Fluid_Core_Parser_ParsingState->render#175 // Tx_Fluid_Core_Parser_SyntaxTree_RootNode->evaluate#91 // Tx_Fluid_Core_Parser_SyntaxTree_AbstractNode->evaluateChildNodes#38 // Tx_Fluid_Core_Parser_SyntaxTree_ViewHelperNode->evaluate#54 // Tx_Fluid_Core_ViewHelper_AbstractViewHelper->initializeArgumentsAndRender#181 // Tx_Fluid_Core_ViewHelper_AbstractViewHelper->callRenderMethod#231 // call_user_func_array#243 // Tx_Fluid_ViewHelpers_Be_ContainerViewHelper->render# // Tx_Fluid_Core_ViewHelper_AbstractViewHelper->renderChildren#105 // Tx_Fluid_Core_Parser_SyntaxTree_AbstractNode->evaluateChildNodes#272 // Tx_Fluid_Core_Parser_SyntaxTree_ViewHelperNode->evaluate#54 // Tx_Fluid_Core_ViewHelper_AbstractViewHelper->initializeArgumentsAndRender#181 // Tx_Fluid_ViewHelpers_RenderFlashMessagesViewHelper->initialize#230 // t3lib_div::logDeprecatedFunction#35 (fluid/Classes/ViewHelpers/RenderFlashMessagesViewHelper.php#34)|
