I’m having a problem testing my input field in a robolectric test. I have a custom phone number visual transformation, and i’m trying the following test code:

composeRule.onNodeWithTag("input2")
                .performTextReplacement("5558675309")

And this causes the following error

offset(14) should be less than line limit(0)
java.lang.IndexOutOfBoundsException: offset(14) should be less than line limit(0)

	at androidx.compose.ui.text.platform.AndroidParagraph.getCursorRect(AndroidParagraph.android.kt:328)

I’m guessing this is due to the use of the visual transformation. Anyone have any ideas?

Update. This is a robolectric issue that's fixed in 4.9.1 that was published 2 days ago
