            JS Gantt chart is not loading from database
            Asked 2021-May-28 at 08:32

            I am trying to create a simple example with DHTMLX Gantt. I have managed to get it working until storing data in the database. Data get stored, but I am not able to load the chart on opening the page. Any ideas what might be the problem? I have gone through the documentation available, but I can't find the root cause of this behavior.

            This is how SQL Server looks like after triggering Save button on Gantt chart:

            Lambda capture-by-value while transfering ownership
            Asked 2021-May-23 at 17:15

            I have a RAII style class which manages the ownership certain resources. Therefore, copy constructor and assignment operator are explicitly deleted, only move variants exist and they move the resource and invalidate the source (reference). So far it has worked fine, but now I would like to move an object of that kind into a std::function which is processed somewhere else, so that this object becomes the ownership carrier, and eventually release the object. Luckily C++14 allows one to use move assignment while capturing by value so it looked like the way to go. Something like:



            Answered 2021-May-23 at 17:15

            A lambda is not a std::function.

            You are right that c++14 allows moving something into a lambda, and even move said lambda afterwards.

            A std::function on the other hand requires the callable to be Copy Constructable and Copy Assignable.

            From cppreference

            Class template std::function is a general-purpose polymorphic function wrapper. Instances of std::function can store, copy, and invoke any CopyConstructible Callable target -- functions, lambda expressions, bind expressions, or other function objects, as well as pointers to member functions and pointers to data members.

            The stored callable object is called the target of std::function. If a std::function contains no target, it is called empty. Invoking the target of an empty std::function results in std::bad_function_call exception being thrown.

            std::function satisfies the requirements of CopyConstructible and CopyAssignable.

            Some ideas for a possible solution could be:

            • Create your own function wrapper (or use a library) that supports move-only callables.

            • Wrap you std::unique_pre in a std::shared_ptr and capture that.

            The first option seems much more robust, but just to show the idea for a quick dirty work-around.



            Include JavaScript component into Blazor component
            Asked 2021-May-16 at 19:51

            I am just starting with Blazor, trying to set up some simple project to see how to interact with different parts and components. I have been trying to include dhtmlxGantt into Blazor index page. It seems to be working by replacing index.html content with example from dhtmlxGantt. However as a result I get only gantt chart without any other Blazor components. How to do it in a proper way so that as a result I would see gantt chart on first page index.razor?




            Answered 2021-May-16 at 19:51

            Consider injecting the javascript so that it runs immediately after Blazor starts on the page.

            One way we may be able to accomplish this is by changing the way Blazor begins when the page is first loaded.

            In wwwroot/index.html (Blazor WebAssembly) or Pages/_Host.cshtml (Blazor Server) we can modify the Blazor initializing to invoke a script after Blazor starts.

            For Example (Blazor WebAssembly):

            Java using @value to construct a member field size
            Asked 2021-Feb-04 at 05:29

            I am using guava cache where I want to keep maximum size configurable. I tried using @value for this but the problem is private member cache gets created before @value injection. How can I read this size from config properties? The code I am currently using is given below



            Answered 2021-Feb-03 at 07:20

            You can put the cache creation in a method that is annotated with @PostConstruct



            How can I display the version of my sitepackage in the frontend?
            Asked 2020-Nov-30 at 09:32

            I want to display the version of my sitepackage (from my declaration file ext_emconf.php ) in the frontend.

            How do I query this information? I was thinking of using a DataProcessor in my FLUIDTEMPLATE, but I’m not sure whether I need to write my own or if there’s already one I can use for that.

            Thank you!



            Answered 2020-Nov-30 at 09:28

            Depending on your exact needs you could make use of ExtensionManagementUtility::getExtensionVersion() to inject a global TypoScript constant via ExtensionManagementUtility::addTypoScriptConstants():



            aws cloudformation package transforms some local paths to S3 uris but not all
            Asked 2020-Sep-18 at 12:15


            I use local paths to reference code for lambda functions and a state machine in the template.yml file describing my cloudformation setup. Transforming these to S3 uris with aws cloudformation package works for the lambda functions, but not the state machine that I'm trying to add to the setup.


            I have a SAM/Cloudformation template, template.yml, that relies on paths that apply to my local repo to access both lambda functions and state machine setup files.




            Answered 2020-Sep-17 at 22:42

            Sadly, DefinitionUri for AWS::Serverless::StateMachine is not supported for such substitutions. In contrast CodeUri is supported, thus its correctly changed.

            How to resolve this dilemma when using generics in a simple factory
            Asked 2020-Aug-12 at 12:03

            I have a Data class with several sub-class such as JSONData, XMLData, IntegerData. The task is to process different types of incoming data. So based on program to an interface, not an implementation, I created the following interface with generic type for compile-time type checking:



            Answered 2020-Aug-11 at 08:06

            This is the classic problem with Java as it doesn't support double dispatching. People have circumvented the problem using visitor pattern. In your case, you can possibly expose a visit function inside the Data class that accepts the DataProcessor and run the process method of it. Essentially, reverse the things.

            Something like this

In the past the had @ManytoMany mapping and the owner was Two, i had to change it to the following for it to work. now one.voiceFeatures.add(Two); and commit is working fine.



            Installing Eclipse PDE Plugin in Windows
            Asked 2020-Jul-30 at 20:33

            I am having difficulty getting my Eclipse PDE plugin to work in a Windows environment. I have created an Eclipse PDE plugin that uses external jars. I was able to install the plugin to my Eclipse IDE on my MacBook (macOS Catalina 10.15), by right clicking on the project then Export>Deployable plugins and Fragments>Install into host repository>Finish. The pathway for the host repository is /Users/username/eclipse-workspace/.metadata/.plugins/org.eclipse.pde.core/install/. The attributes chosen in the Options category are shown in the photo below:

            The plugin installs successfully and is able to run in my IDE upon button click.

            When I repeat these steps in Windows 10, the plugin installs. I am able to click on a button to open my developed window, but when I click the "go" button which triggers my functions that rely on the external jars, nothing occurs. The button acts as though it is not connected to any function, despite the code being identical to what was used in Mac. Does anyone know why Eclipse is unable to access the necessary jars in Windows?

            I have attached a screenshot of my build properties below. Note that the jars are held in a directory called "lib" which is at the same level as the /src directory in a eclipse plugin project.



            Answered 2020-Jul-30 at 20:33

            Update: the issue appeared to be with the windows computer I was using. The plugin installed as intended with this code on another windows machine.
