Failed to parse URL when bulding nextjs client in api platform

20 April 2024 @ 11:57 am

I've been trying to play around with api platform these last few days. However I must be missing somethign. When I follow the steps in "getting started with...", to generate the nextjs client, everything seems to work: I can go to localhost/greetings and I can add, edit and delete greetings. However, after that I tried to follow This fails in the build step of the pwa with the error TypeError: Failed to parse URL from undefined/greetings. This is the same error I get when following the steps to build a nextjs client here: Here it says to go to localhost:3000/greetings after starting the server with pnmp dev. Going to that page gives me the same error as I wrote above. After this, the page that originally worked (localhost/greeti

Data not loading on Page refresh in blazor webassembly standalone app

20 April 2024 @ 11:56 am

I have created a sample web app in blazor as webassembly standalone app, then I simply published this web app in a local folder and hosted it in the iis as a website. I browse the site it worked properly but I refreshed the page then got the error page. I looked for the issue on internet then I found one setting to be done in the web.config file of the application. I did the same and error page did not come but the data was also not loaded which I am fetching from the sql server. Currently the sql server is in the same machine but I want the solution for both sql server in local machine sql server on a hosted server. Also the menus given in the left hand side got hidden and I was unable to expand them using the menu button just like app got hannged. On browsers back button I went back then app started working but the page refresh issue still persists.

My HashSet stored a duplicate object after a modification

20 April 2024 @ 11:53 am

I am a programming tutor. Yesterday, I was trying to explain HashSet to my students in some test cases. Of course, HashSet allows modifying contained objects, but it can lead to inconsistency problems, and I was showing them some ways to do this correctly. Then, I encountered a situation where my HashSet added an object that was already in it after a modification. Could anyone explain to me why it happens? Here is my code: boolean cambiar = false; Persona personaCambiada = null; Iterator<Persona> iteratorHS = hs.iterator(); while (iteratorHS.hasNext()) { Persona persona =; if (cambiar == false) { personaCambiada = persona; iteratorHS.remove(); personaCambiada.setDNI(p2.getDNI()); personaCambiada.setNombre(p2.getNombre()); cambiar = true; } } System.out.println(p2.equals(personaCambiada)); // prints true System.out.println(personaCambiada.equa

How to prevent component reload when toggling Modal visibility?

20 April 2024 @ 11:35 am

I am using a Modal in my RN app to show a map to the user. This component is slow and expensive to load, which is why I want to make sure it is not getting loaded from scratch every time. However, currently this is not working. By toggling visible, the map component gets loaded from scratch each and every time the modal opens up again. Is there a way to prevent this behavior and make sure that the map is not getting unmounted and reloaded every time? import { Modal } from 'react-native'; <Modal animationType="slide" transparent={true} visible={showModal} onRequestClose={() => setShowModal(false)}> <MapView onTogglePressed={() => setShowModal(false)} /> </Modal>
