syntaxHighlighter on decompiled file Follow

Hi. I have implemented a BinaryFileDecompiler attached to a FileType with method isBinary overridden.

I've also created a PsiFileBase for my compiled fileType and attached to the method createFile() in a ParserDefinition class

Decompiler works, but syntax highlighting does not work.

object MyParserDefinition : ParserDefinition {
...
override fun createFile(viewProvider: FileViewProvider): PsiFile = when (viewProvider.fileType) {
    MySourceFileType -> MySourceFile(viewProvider)
    MyIncludeFileType -> MyIncludeFile(viewProvider)
    MyCompiledFileType -> MyCompiledFile(viewProvider)
    else -> throw RuntimeException("Illegal viewProvider") // is this ok?
}
}

object MyCompiledFileType : FileType {
    override fun getName(): String = "MY_COMPILED"
    override fun isReadOnly(): Boolean = true
    override fun isBinary(): Boolean = true
    ...
}

class MyCompiledFile(viewProvider: FileViewProvider) : PsiFileBase(viewProvider, MyLanguage) {
    override fun getFileType(): FileType = MyCompiledFileType
    override fun toString(): String = "compiled file viewProvider"
}

Then, if I try to add a syntaxHighlighter, even with implementationClass value empty, I can open my compiled file, but it shows a infinite "Loading…" text.

Is it normal? Am I missing something to implement?

This is a similiar issue: https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000006644-Parsing-decompiled-source-using-target-language-s-extensions , but his solution (including the syntaxHighlighter) does not work
