MapViewer tile layer preview error in OBIEE 11.1.1.7

Question

Some folks have run into an issue when previewing tile layers in the manage tile layers page of MapViewer in obiee 11.1.1.7 (i.e. in the mapviewer deployed on wls in obiee).
If you get a 500 - internal server error when trying to view map/manage tiles from the Manage Tile Layers page then you have to apply the workaround/fix described in the mapviewer 11.1.1.7 readme
Known issues =============================================
- On certain WLS domains (mostly when ADF run-time library is deployed), you
  may see errors when trying to preview tile layers. To fix this issue, modify
the weblogic.xml descriptor file found in mapviewer.ear's WEB-INF/ folder, and
uncomment the entry for the jstl 1.2 library as shown below (note the jsf
section should remain commented-out):
<library-ref>
  <library-name>jstl</library-name>
  <specification-version>1.2</specification-version>
  </library-ref>
<!--
<library-ref>
  <library-name>jsf</library-name>
  <specification-version>2.0</specification-version>
  <exact-match>false</exact-match>
</library-ref>

Hi Cristian,
You must use '' at script when call some column value. (use '@1' instead of @1)
Tip.. note you can use your "WebMessage Name" (from your script, like "filling", "machine_filing") into your analisys.
Hope this help
