Problem about QueryNamedPropertyHistory

Hi,

I want to export data from a thing's property.

I used the service "QueryNamedPropertyHistory".

I define a service named "GetMyProperty" to pass parameters to the "PropertyNames"  of "QueryNamedPropertyHistory".

Through the above i want to assign the properties which will be exported.

The error is "Unable to Invoke Service QueryNamedPropertyHistoy". It seems that the parameters isn't passed  successfully by the service "GetMyProperty".

In this picture, you can see that I assign properties in list and add them to the table in the right. The conent in the table was listed by using the service "GetMyProperty".

I have resolved the problem.

The tables display the results of the service "GetMyProperty" and "QueryNamedPropertyHistory" must in the same page.

You can understand what i mean by seeing the picture below.

Re: Problem about QueryNamedPropertyHistory

are you using name (lower case n) vs. Name in your datashape?

I think it specifically needs name (lower case n)

I use lower case n in the datashape.

In the mashup, it appears as a captial N in a table title.
