[wix-users] WiX EULA print button prints wrong file

[Julius Kukonenko]

Hi. I have a WiX installer v3.11. I created a simple CustomDialog with a
print button and I have a regular WelcomeEulaDlg with print button. My
custom window is showing before Eula. When I press the print button on
WelcomeEulaDlg it somehow takes my custom dialog file. And I don't know
why... Here's my code:

    <MajorUpgrade AllowDowngrades="no" DowngradeErrorMessage="A newer
version of [ProductName] is already installed."
AllowSameVersionUpgrades="yes" Schedule="afterInstallExecute"/>
    <MediaTemplate EmbedCab="yes"/>

    <WixVariable Id="WixUILicenseRtf" Value="$(var.SolutionDir)\EULA.rtf"/>

    <PropertyRef Id="NETFRAMEWORK45" />

    </UI>
    <UIRef Id="WixUI_Common" />


My custom dialog code:

	<Fragment>
    <CustomAction Id="PrintEula" BinaryKey="WixUIWixca"
DllEntry="PrintEula" Return="ignore" Execute="immediate" />
    <UI Id="LoggingInfoDlg">
      <Dialog Id="LoggingInfoDialog" Width="370" Height="270"
Title="MyInstaller">
        <Control Id="Bitmap" Type="Bitmap" X="0" Y="0" Width="370"
Height="234" TabSkip="no" Text="!(loc.WelcomeEulaDlgBitmap)" />
          <Control Id="Title" Type="Text" X="130" Y="6" Width="225"
Height="30" Transparent="yes" NoPrefix="yes"

          <Control Id="BottomLine" Type="Line" X="0" Y="234"

        <Control Id="Print" Type="PushButton" X="180" Y="243"

            <Publish Event="DoAction" Value="PrintEula">1</Publish>
          </Control>
        <Control Id="Next" Type="PushButton" X="236" Y="243"
Width="56" Height="17" TabSkip="no" Default="yes" Text="Next">
          <Publish Event="NewDialog" Value="WelcomeEulaDlg">1</Publish>
          </Control>
        <Control Id="Cancel" Type="PushButton" X="304" Y="243"
Width="56" Height="17" Cancel="yes" Text="!(loc.WixUICancel)">
            <Publish Event="SpawnDialog" Value="CancelDlg">1</Publish>
          </Control>
        <Control Id="LicenseText" Type="ScrollableText" X="130" Y="55"
Width="225" Height="150" TabSkip="no" Sunken="yes">
          <Text SourceFile="$(var.SolutionDir)\GDPR.rtf" />
        </Control>
      </Dialog>
    </UI>
  </Fragment>


So my variable WixUILicenseRtf is set to EULA.rtf and the scrollable text
is showing fine. but somehow when I press the print button It prints
GDPR.rtf file instead of EULA.rtf. What I'm doing wrong?
