Pchp.Library.Spl.TypeError: "A scalar of type 'double' used as an object" #1067

Closed FibonacciFox closed 1 year ago

FibonacciFox commented 1 year ago

Hello, peachpie team! I am working on creating a software development environment using peachpie. Faced with such a problem.

Creating a button click event in php

image

How is this implemented in c# private readonly IDictionary<string, EventHandler<RoutedEventArgs>> _events; image

Error: image

1. This error occurs with any scalar type that I pass to an anonymous php function. 1.1.This error occurs only if an anonymous function is called in a c# event.

The Content property has the object type.

image If you redefine the Content property in: image There will be no mistakes!

If the anonymous function is called as is, there will be no errors outside of events, the code works!
If you pass a parameter to an anonymous function and call it in an event, the error described above will occur!
It is impossible to bring it to the desired type, the error occurs at the stage of accessing the Content property

If you declare : $content = 123.1; inside an anonymous function, it will not cause errors. The Content property will be NULL

We see this behavior only when we call any event.

And redefining properties in the framework from the object type to PhpValue will be a very time-consuming process.

Hi @FibonacciFox !

Do you have a stack trace of the exception? I recommend also disabling "Just My Code" when debugging (depends on your IDE).

@jakubmisek, I hope this helps.

This is the MainWindow.php, line 51. right?

$button->Content = $content1;

In PHP, $content1 (double) can't be assigned to object. But I understand, that in .NET it is a common practice boxing any value to object. Currently, $content1 must be a PHP object to pass the assignment.

@jakubmisek, thank you for your help. I can't understand: image

jakubmisek commented 1 year ago

This behavior seems to be a bit inconsistent ... what should work now, is assigning only PHP object (class instance) to the $button->Content;

It's actually unexpected, that "works!" works.

We have to make it work in both cases.

thank you @FibonacciFox
