Virtual keyboard not visible

[manny_lp]

I have a sample application which has scrollable text area and input panel. When user clicks on text area, keyboard should appear and height of text area should be adjusted.
1. I see that first time when I click on text area, keyboard is not visible! Click again and keyboard comes up.
2. Also, I see a binding loop error: qrc:/main.qml:6:1: QML QQuickWindowQmlImpl*: Binding loop detected for property "conclusionAreaHeight"*

Please share your suggestions.

import QtQuick 2.9
import QtQuick.Window 2.2
import QtQuick.Controls 2.2
import QtQuick.VirtualKeyboard 2.2

Window {
    visible: true
    width: 1280
    height: 480
    title: qsTr("Hello World")

    property int conclusionAreaHeight: Qt.inputMethod.visible ? 85 : 480
    property int conclusionLength: 511

    Rectangle{
        color: "white"
        border.color: "#eeeeee"
        height: conclusionAreaHeight
        width: 1000
        anchors.margins: 15
        anchors.horizontalCenter: parent.horizontalCenter
        ScrollView {
            id: conclusionViewId
            anchors.fill: parent
            contentWidth: conclusionViewId.width - 35
            clip: true

            TextArea {
                id: conclusionTextAreaId
                wrapMode: TextEdit.WrapAtWordBoundaryOrAnywhere
                focus: false

                property string previousText: text

                /*to limit no. of characters*/
                /*Text area does not have validator property, hence the work around*/
                /*Refer https://bugreports.qt.io/browse/QTBUG-12304*/
                onLengthChanged: {
                    if(length > conclusionLength){
                        var cursor = cursorPosition;
                        text = previousText;
                        if (cursor > text.length) {
                            cursorPosition = text.length;
                        } else {
                            cursorPosition = cursor-1;
                        }
                    }
                    previousText = text
                }
            }
        }
    }


    InputPanel{
        id: keyboardId
        width: 800
        visible: active
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.bottom: parent.bottom
