This has been discussed in this list many times before. You need to set your
property to the new value of the property when the action returns before
using it in the dialog.
<Control Type="PushButton" Id="Validate" Width="56" Height="17" X="234"
Y="243">
<Text>Validate</Text>
<Condition Action="disable">
<![CDATA[VALIDATED = "1" ]]>
</Condition>
<Publish Event="DoAction"
Value="ConfirmationCustomAction">1</Publish>
<Publish Property="VALIDATED" Value="[VALIDATED]">1</Publish>
<Publish Event="SpawnDialog"
Value="InvalidConfigDlg"><![CDATA[VALIDATED <> "1" ]]></Publish>
</Control>

Subject: [WiX-users] Changing a Global property in a custom action is not
immediately affecting the installer
Hello!
I have a custom action setting a Global property in the following way:
session[VALIDATED] = "1";
This CA is called when a user clicks a "Validate" button in a dialog.
The control is as follows:
<Control Type="PushButton" Id="Validate" Width="56" Height="17" X="234"
Y="243">
<Text>Validate</Text>
<Condition Action="disable">
<![CDATA[VALIDATED = "1" ]]>
</Condition>
<Publish Event="DoAction"
Value="ConfirmationCustomAction">1</Publish>
<Publish Event="SpawnDialog"
Value="InvalidConfigDlg"><![CDATA[VALIDATED <> "1" ]]></Publish>
</Control>
Now i have a "Next" button in the same dialog, which is initially Disabled,
and gets enabled when the VALIDATED
property get's set to 1:
<Control Type="PushButton" Id="Next" Width="56" Height="17" X="308" Y="243"
Default="no">
<Text>Next</Text>
<Condition Action="disable">
<![CDATA[VALIDATED <> "1" ]]>
</Condition>
<Condition Action="enable">
<![CDATA[VALIDATED = "1" ]]>
</Condition>
<Publish Event="EndDialog" Value="Return"/>
</Control>
Initially the Property VALIDATE is set to "0".
Now when i run the installer, and i click "Validate", i can see in the log
files that the Property VALIDATE is set to 1
(PROPERTY CHANGE: Modifying VALIDATED property. Its current value is '0'.
Its new value: '1'.
Action ended 14:38:57: ConfirmationCustomAction. Return value 1.),
but when the custom action returns ActionResult.Success,
the Next button is still Disabled.
I have a bunch of edit boxes in my dialog, each one representing a Property.
A senario that i realised that i can enable the "Next" button is:
1) I fill in all the edit boxes
2) I click Validate
3) The CA returns ActionResult.Success (Next button STILL disabled)
4) I re-edit an edit box
5) When i re-edit, the next button get's enabled. (and Validate get's
disabled)
Any ideas why this is happening?
Under normal circumstances, when the CA ends and is successfull, the Next
button should get enabled.
Thanks in advance,
Stelios
