Publish bug

[jbester-premcloud]

I have the following publish element in a project:

<Publish Dialog="DatabaseConfigDlg" Control="EditInstance" Event="Enable" Value="-" Condition="DB_TYPE = SQLServer"/>

If I take out the "Value" attribute, it results in error WIX0010: The Publish/@value attribute was not found.

If I set the value to an empty string, it results in error WIX0006: The Publish/@value attribute's value cannot be an empty string. If a value is not required, simply remove the entire attribute.

Clearly there is no way to have an empty string as value, since the conditions oppose one another.

The documentation for the Publish element says you must specify the Value attribute when sending an event. You can remove the Value attribute when setting a Property attribute. This is a Windows Installer limitation, not a WiX limitation.

Note: the Publish element, like a few of the UI elements, is a bit overloaded. That's a throwback to WiX v1 days.

Thanks for clarifying. I assume then that the message of leaving out the element is determined by the XML parser, not Wix itself.

No. Those are WIX### error messages.
