Request for information on using the idQ attribute for custom ribbons in Access.

Hello,

Here is in more detail, the result of my tests with the idQ attribute for which I am looking for information.

Here is the Xml code of the 2 ribbons, part of which is shared

rbForm1

<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" xmlns:Q="Test">
	<ribbon startFromScratch="true">
		<tabs>
			<tab visible="true" label="Test idQ" idQ="Q:tab1">
				<group label="Test" idQ="Q:group1">
					<button size="large" label="Shared" imageMso="AppointmentColor1" idQ="Q:button1" onAction="rbForm1_OnAction"/>
					<button imageMso="AppointmentBusy" size="large" onAction="rbForm1_OnAction" id="button2" label="Form1"/>
				</group>
			</tab>
		</tabs>
	</ribbon>
</customUI>

rbForm2

<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" xmlns:Q="Test">
	<ribbon startFromScratch="true">
		<tabs>
			<tab visible="true" label="Test idQ" idQ="Q:tab1">
				<group label="Test" idQ="Q:group1">
					<button imageMso="AppointmentColor3" size="large" id="button1" label="Form2"/>
				</group>
			</tab>
		</tabs>
	</ribbon>
</customUI>

Here is the illustration with the startFromScratch="false" attribute working perfectly fine.

Here is the illustration with the startFromScratch="true" attribute not working.

The 'Test idQ' tab disappears when selecting the 'Form 2' form

Here is the illustration of the 'OnAction' event on the unsplit button of the Form 1 form.

This event works correctly.

Here is the illustration of the 'OnAction' event on the Form 1 split button.
