It comes from B4XRadioButton (XUI Views). Have you created a class named B4XRadioButton?

StarinschiAndrei · Jun 8, 2021

Hi Erel , i created and here is the error :
B4J Version: 9.00
Parsing code. Error
Error parsing program.
Error description: B4XRadioButton is declared twice. You should either remove the library reference or the code module.
even if i removed the code module

Make sure that you really removed it and clean the project.

It's a hard compilation error so somewhere you have a declared object called 'rb' that is of a type that does not have a 'checked' property.

There is "rb." only in xChart class. This class wasn't modified.

Have you looked in your Designer scripts?

We don't know without seeing the code. Post an example.

Error occured in line 105
rb.Checked = False

There is a rb.Checked = False in Line 105 in the B4XRadioButton CustomView from the XUI Views b4xlib.

Do you use XUI Views?
Which version do you use? The latest is version 2.50.
Do you use B4XRadioButtons ?

I just tested a small program using an xChart Bar chart where rb is used and two B4XRadioButton with no problems.

Dear Klaus,
I use XUI Views ver. 2.50, but didn't use B4Xradiobutton. As you can see in my previous post i tried to find "rd." but there isn't anywhere
Thank you

Can you post your project as a zip file?

Attached you can find my zip project

I don't have the jSD_XUIView library. I guess that this library also has a B4XRadioButton type.

I had a look at your project.
It needed some time to find quite a lot of libraries I did not have.
I got a message about this missing library mariadb-java-client-2.2.0.jar, but I did not find it.
So I commented this line: '#AdditionalJar:mariadb-java-client-2.2.0.jar
And the program compiles without any error.

And this is the libraries list.

I noticed, when I got messages about missing libraries, that the compiler is looking in the platform libraries folder not in the AdditionalLibraries folder.
It seems that you are saving additional libraries into the platform libraries folder.
Maybe the problem is there.

I added XLUtils libraray but same error. I didn't change anything in my b4j environment , only installed the new version.
I commented this line: #AdditionalJar:mariadb-java-client-2.2.0.jar as you did but i got the same error.

I had added XLUtils because I had to look for quite some libraries and didn't know if this one was needed or not.
XLUtils is not needed. I removed it.
Then I removed following libraries and the program still works:
- XUI Views, the rb.Checked = False line is in this one
- xCustomListView

Do you really need these libraries ?
I see that you have a lot of warnings.
Is the project you posted a stripped down one?
If no, you must look at the warnings and correct them, if no, one day you will get trouble.

As you have not commented my remark about the location of additional libraries.
I suggest you to uninstall B4J and reinstall it in an empty folder. This will clean the platform Libraries folder.
Then run your project and add any missing library into the AdditionalLibraries folder.

My guess is that it is related to a conflict between XUI Views and jSD_XUIView. Try to reproduce it in a new project with these libraries.
