ClearSelection works in Silverlight (v1.9), but not HTML5 (v1.2)
I have two simple workflows that have 3 steps each: ClearSelection, QueryTask, and SelectFeatures. One of the workflows queries out buildings where "TYPE = 'Restaurants/Bars'" The other workflow queries out buildings where "TYPE = 'Government'" Both should clear the previous selection before performing the query and selection.
When I use Silverlight 1.9's viewer to run the Restaurants/Bars workflow, 28 results show. If I run the other workflow, 14 Government buildings show up; perfect.
However, when I use HTML 5 1.2's viewers to do the same steps, the Government buildings workflow does not clear the 28 Restaurant results (for Desktop and Tablet); and the Handheld version goes on to add the Government results to the Restaurant results for a total of 42 results.
Has anyone else seen this? Thank you in advance for any responses.

Matt from Latitude Geographics' support group resolved this problem for me. He pointed out that ClearSelection is classified as an "external command," which can be viewer-specific (meaning that Silverlight supports it, but HTML5 does not). Moreover, to get my last selection to clear appropriately in an HTML5 viewer, I must utilize the option within the SelectFeatures command to "Clear Collection First."
After trying Matt's suggestion, my workflows began to function correctly.
