"OutOfBoundsException" When hitting Enter

Hi Tomas, I changed my code to match the method you gave me before. See code below and the generated error. This is the full stack trace of the error:

The steps are:

Click in text area, apply a font size,.. things work fine..
Then hit Enter.. the error comes up.

I isolated the code that triggers the error, which is this:

public void doTheCaretStyleChange(TextEditorViewPort port, StyleInfo style) {
port.viewPortRichText.plainTextChanges().subscribe(change -> {
int from = change.getPosition();
int length = change.getInserted().length();
port.viewPortRichText.setStyle(from, from + length, style.completeInLineCSS.get());
});
}

I added this and it seems to prevent the errors... (here caret is at the end of the text.)
if (from > from + length) {
port.viewPortRichText.setStyle(from, from + length, style.completeInLineCSS.get());
}

but it stops applying styles all together. so I guess it is when the Enter key is hit, things go wrong somewhere...

Yep Confirmed. It is the Enter key. The code below works fine.

if (!change.getInserted().equalsIgnoreCase("\n")) {
port.viewPortRichText.setStyle(from, from + length, style.completeInLineCSS.get());
System.out.println("Applying Style: <<" + style.completeInLineCSS.get() + ">> at Caret");
} else {
System.out.println("Hitting Enter. Ignoring style application at caret");
}

Good debugging work!

Thanks did u manage to fix it?

I noticed one thing though.

If I want to apply a style using this method, it takes a very precise work
flow.

For example, click in the size button. Select a size. Click in the text
area. Click apply. Then start typing for the new style to take place.

If you click again in the same position you will need to redo all steps.

Also for some reason, it does not work right away for me. I have to try a
couple of times. My guess is that waits on applying the style until the
user starts typing.

I went with another one method, i apply a style to caret position + one
step to the right (I add a white space after it if caret position is at the
end) . it is less accurate but works right away.

Can you reproduce the issue?
