Are propertyConditions for actions supported in the HTML client?

When using the propertyConditions in the html client my actions are not be shown in the menu as expected. These actions allow the actions to be shown in the Flex client.

I verified our property provider is being called and is returning values that should enable the action to be shown in the menu. 

If I remove the propertyCondition and only use objectType to restrict the action then the action shows in the menu. Here is the metadata I'm using on both the action.sets and the solutionsMenus:

        <metadata>

            <objectType>VirtualMachine</objectType>

            <propertyConditions>

                <com.vmware.data.query.CompositeConstraint>

                    <nestedConstraints>

                        <com.vmware.data.query.PropertyConstraint>

                            <propertyName>sample:isMyVm</propertyName>

                            <comparator>EQUALS</comparator>

                            <comparableValue>

                                <String>true</String>

                            </comparableValue>

                        </com.vmware.data.query.PropertyConstraint>

                        <com.vmware.data.query.PropertyConstraint>

                            <propertyName>sample:isTemplate</propertyName>

                            <comparator>EQUALS</comparator>

                            <comparableValue>

                                <String>false</String>

                            </comparableValue>

                        </com.vmware.data.query.PropertyConstraint>

                    </nestedConstraints>

                    <conjoiner>AND</conjoiner>

                </com.vmware.data.query.CompositeConstraint>

            </propertyConditions>

        </metadata>

Any thoughts or ideas on how to trouble shoot?
