Dear,

I am looking for help after updating our Galaxy production server to release 
2014.08.11, one of our in-house tool does not load in Galaxy anymore. I do 
think the problem is related to the conditional parameter because when I 
comment this section out Galaxy does display it. Any ideas where the problem 
could be?

Here is the xml file:

<tool id="hm" name="heatmap-public">
  <description>Creates a heatmap from public datasets</description>

  <command interpreter="R --vanilla --slave -f">
    #silent sys.stderr.write("!!!! Cheetah Template Variables !!!!\n")
    #for k,v in $searchList[2].items()
    #silent   sys.stderr.write(" %s = %s\n" % (str(k), str(v) ))
    #end for
    
    ## path to the dataset selected extracted from the 'cri_datasets' data 
table (tool-data/cri/datasets.loc)
    #import os
    #set $dataset_relative_path = filter( lambda x: str( x[0] ) == str( 
$dataset.name ), $__app__.tool_data_tables[ 'cri_datasets' ].get_fields() 
)[0][-1]
    #set $dataset_path = os.path.join($__tool_data_path__, 
$dataset_relative_path)
