Conditional Feature based on Property - wix

Question

In my bundle I have 2 features which both are about creating a folder structure based on the value of a property. As you can see my conditions are fairly simple. What is interesting is that only the condition on feature ONE works, while in feature TWO (where it does a comparison) it does nothing, but If I add the condition on every component I need just like in the other pasted code it works fine.
I was wondering why this is happening
<Property Id="NUMBER" />
<Feature Id="ONE" Level="0">
<Condition Level="1">
<![CDATA[NOT NUMBER]]>
</Condition>
<ComponentGroupRef Id="OneStructure"/>
</Feature>
<Feature Id="TWO" Level="0">
<Condition Level="1">
<![CDATA[NUMBER <> ""]]>
</Condition>
<ComponentGroupRef Id="OneStructure"/>
</Feature>
-
<Directory Id="dir77996843FCCE5E3734A5EDAA86FCE55B" Name="Input">
<Component Id="cmp2F4C23D858A887EF0B2539F7EC1884BE" Guid="{625D2714-157F-4B21-86C0-D4954A4E1F73}" KeyPath="yes"> <Condition> <![CDATA[NUMBER <> ""]]> </Condition>
<CreateFolder />
</Component>
</Directory>

Had the same issue. Apparently it has to do with the condition only being evaluated once.
Instead of putting a condition directly in a feature, you can put conditions in a Control Event pertaining to a button in a given dialog.
Example:
<Control Id="Install" Type="PushButton" X="304" Y="243" Width="56" Height="17" Default="yes" Text="Install">
<!--Check property value here:-->
<Publish Event="AddLocal" Value="ALL">1</Publish>
<Publish Event="Remove" Value="ONE">NUMBER = 0</Publish>
<Publish Event="Remove" Value="TWO">NUMBER = 1</Publish>
<Publish Event="EndDialog" Value="Return" />
</Control>
You would then change the value of the property "NUMBER" with a Radio Button.
Hope this helps!
