Hi there,

I'm making an API call which returns this:

B4X: 
(MyMap) {success=1}

Then, I've this code to validate a success return code:

B4X: 
If res.GetDefault("success", "") = "1" Then

To my surprice, this "If" isn't True... If I change it to:

B4X: 
If res.GetDefault("success", "") = 1 Then

It works but the IDE complains:



What's the correct way to deal with this?

Thanks.

Did you try to put the object on the right side of the comparison?

Like so:
B4X: 
If 1 = res.GetDefault("success", "") Then

B4X: 
If 1 = res.GetDefault("success", FailValue)  Then

Where FailValue is whatever the fail value should be, presumably an int.

Edit: I was too slow

I ended up doing the

B4X: 
Dim wasSuccess As String = res.GetDefault("success", "")
If wasSuccess = "1" Then
End If

To avoid IDE complains...

I'm just wondering how will I avoid future bugs based on the... I was hoping that:

B4X: 
If res.GetDefault("success", "") = "1" Then

would be evalutated in "String" context...

The IDE is giving you the actual solution, I don't know why you're not taking the advice.

Anyway, here's a post that might explain things:

B4J v8.30 BETA is available for download

Improvements: Support for Java 14. As with Java 11, B4J expects a specific structure. You should download this package (OpenJDK 14 + OpenJFX 14): https://b4xfiles-4c17.kxcdn.com/jdk-14.0.1.zip Build standalone package - B4JPackager11 is now integrated in the IDE. This makes it simpler to build...
