[wix-users] How come the RTF content in the ScrollableText be modified dynamically using session.Database.OpenView and InsertTemporary

[Shintaro Takechi]

By the way, the ScrollableText side is implemented as following.
I can see in the orca that text is properly assigned and the UI is
displaying the "default text" correctly.

<Control Id="Verification" Type="ScrollableText" X="180" Y="80" Width="410"
Height="280" Sunken="yes" TabSkip="no"
Text="{\rtf1\ansi\deff0{\colortbl;\red0\green0\blue0;\red255\green0\blue0;}default
text\line}"/>

I am attempting to update the Text column to following Rich Text Content.

{\rtf1\ansi\deff0{\colortbl;\red0\green0\blue0;\red255\green0\blue0;}
\cf1
This line is the default color\line
\cf2
This line is red\line
\cf1
This line is the default color
}

If I did not call the CustomAction, the default text is properly displayed.
However, if I attempt to update (and view.InsertTemporary(record)), the
ScrollableText displays nothing. (Not even the default value).
