Android Question Compiler error that make me crazy

[RenewMe]

Hi, i have this code that takes data from an API call and should publish them in xChartLite object, but compiler is telling me : "Unknown member: initialize".
I don't find any initialize command inside . Which is the real reason ?
Thank you in advance

Tip: you don't need a JobDone sub. Correct way to use OkHttpUtils2: https://www.b4x.com/android/forum/threads/b4x-okhttputils2-with-wait-for.79345/#content

The error probably comes from one of the b4xlibs. Just a guess, but if you have a module with a name that conflicts a variable inside the b4xlib then it can cause such issues.

Delete the xChart Custom View from the layout file. Save the file and close the Designer. Reopen the layout and add it again. Sometimes this helps.

That sounds like a bug that you should report.
