Was able to build a minimal app that reproduces the problem. Running the below app immediately throws the above exception: import java.util.Collection;
import java.util.Collections;
import org.fxmisc.richtext.StyleClassedTextArea;
import org.fxmisc.richtext.model.StyleSpansBuilder;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class StyleSpansIssue extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
StyleClassedTextArea textArea = new StyleClassedTextArea();
textArea.replaceText("* a\n\n");
StyleSpansBuilder<Collection<String>> spansBuilder = new StyleSpansBuilder<>();
spansBuilder.add(Collections.singleton("cls1"), 1);
spansBuilder.add(Collections.singleton("cls2"), 3);
spansBuilder.add(Collections.emptyList(), 1);
textArea.setStyleSpans(0, spansBuilder.create());
Scene scene = new Scene(new StackPane(textArea), 600, 400);
primaryStage.setScene(scene);
primaryStage.setTitle("StyleSpansIssue");
primaryStage.show();
}

I'm getting the below exception with current
masterbranch of RichTextFX in Markdown Writer FX, but it works fine with RichTextFX 0.8.2.Was able to find the commit that causes the exception: PR #685
Before this PR was merged, it worked. After merging, it fails.
The exception assumes a problem on my side, but I have no idea how to fix this.
I'm having a
StyleClassedTextAreaand using aStyleSpansBuilder<Collection<String>>to build style spans for the whole text.Any ideas?
The text was updated successfully, but these errors were encountered:
