AEM SiteCatalyst integration: evars with non-numeric values don't fire on any page

Hello,

We have eVars of 'Text string type' in Omniture. It works fine while we use it on non-AEM cms. But when we try to put some non-numeric values to them via AEM SiteCatalyst framework editor nothing happens - this evars not firing. In Admin Console of Omniture there are Text string type of this evars. If we place numeric value to this evars - we'll get them fired with this values.

Evample          non-numeric value            numeric value

text evar1             NO firing                           111

text evar2             NO firing                            222

Very strange for us. PLease, Help.
