More about Property bags and Varant types

When returning values in a property bag that are not string values you will have to break open the XML of the management pack to be able to compare the values correctly.

The XML generated by the Authoring console will look something like:

<ErrorExpression>
<SimpleExpression>
<ValueExpression>
<XPathQuery>Property[@Name='Status']</XPathQuery>
</ValueExpression>
<Operator>GreaterEqual</Operator>
<ValueExpression>
<Value Type="String">7</Value>
</ValueExpression>
</SimpleExpression>
</ErrorExpression>


If returning Integer values that you want to compare with integers you will have to change it to:

<ErrorExpression>
<SimpleExpression>
<ValueExpression>
<XPathQuery Type="Integer">Property[@Name='Status']</XPathQuery>
</ValueExpression>
<Operator>GreaterEqual</Operator>
<ValueExpression>
<Value Type="Integer">7</Value>
</ValueExpression>
</SimpleExpression>
</ErrorExpression>

Note that the Type declaration has to be on both sides of the expression. Also be aware that some version of the Authoring console may strip the Type="Integer" from the XPath query.


Thanks to Alexandre Coelho for this fix.
