Hi!
Deferred Custom Actions cannot return data because of a limitation in
Installer SDK.
It seems that WiX creators tried to create a work around which is available
for C++ only.

Hi,
I tried without success!
I can pass data of CustomAction1 to CustomAction2 -> OK; I can change the
value of session.CustomActionData["SomeCustomActionDataKey”] from 1 to 2!
(see log at the end of this email)
How can I pass SomeCustomActionDataKey, defined in CustomAction1 and
changed in CustomAction2 to CustomAction3 or CustomAction4 too?
This is my code:
Product.wxs:
=======================================
<Property Id="MyVar" Value="1" />
<CustomAction Id="CustomAction1"
Property="CustomAction2"
Value="SomeCustomActionDataKey=[MyVar]"/>
<Binary Id="CustomActionABin" SourceFile="$
(var.CustomActionA.TargetDir)$(var.CustomActionA.TargetName).CA.dll" />
<CustomAction Id="CustomAction2"
BinaryKey="CustomActionABin"
DllEntry="CustomAction1"
Execute="deferred"
Return="check"
HideTarget="no" />
<CustomAction Id="CustomAction3"
Property="CustomAction4"
Value="SomeCustomActionDataKey=WHAT VALUE THERE??"/>
<!-- custom action - riferimento alla dll -->
<Binary Id="CustomActionBBin" SourceFile="$
(var.CustomActionB.TargetDir)$(var.CustomActionB.TargetName).CA.dll" />
<CustomAction Id="CustomAction4"
BinaryKey="CustomActionBBin"
DllEntry="CustomAction1"
Execute="deferred"
Return="check"
HideTarget="no" />
<InstallExecuteSequence>
<Custom Action="CustomAction1" Before="CustomAction2" />
<Custom Action="CustomAction2" Before="CustomAction3" />
<Custom Action="CustomAction3" Before="CustomAction4" />
<Custom Action="CustomAction4" After="InstallInitialize" />
</InstallExecuteSequence>
CustomActionA
=======================================
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Deployment.WindowsInstaller;
namespace CustomActionA
{
public class CustomActions
{
[CustomAction]
public static ActionResult CustomAction1(Session session)
{
session.Log("Begin CustomAction1");
session.Log("session.CustomActionData[\"SomeCustomActionDataKey
\"]={0}", session.CustomActionData["SomeCustomActionDataKey"]);
session.CustomActionData["SomeCustomActionDataKey"] = "2";
session.Log("session.CustomActionData[\"SomeCustomActionDataKey
\"]={0}", session.CustomActionData["SomeCustomActionDataKey"]);
return ActionResult.Success;
}
}
}
CustomActionB
=======================================
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Deployment.WindowsInstaller;
namespace CustomActionB
{
public class CustomActions
{
[CustomAction]
public static ActionResult CustomAction1(Session session)
{
session.Log("Begin CustomAction1");
// this should have value=2!!
session.Log("session.CustomActionData[\"SomeCustomActionDataKey
\"]={0}", session.CustomActionData["SomeCustomActionDataKey"]);
session.CustomActionData["SomeCustomActionDataKey"] = "3";
session.Log("session.CustomActionData[\"SomeCustomActionDataKey
\"]={0}", session.CustomActionData["SomeCustomActionDataKey"]);
return ActionResult.Success;
}
}
}
