This page contains all the caveats and the known workarounds that we are aware of.  Please read through each one to determine if any applies to your particular environment.  Thanks.

Large Patient Set and Long Run Time

Please note that large patient sets (> 5000) may result in rather long run time before the data can be retrieved from the database and the resulting table can be rendered.  This is especially true when using the Safari browser. 

php.ini Setting and Resulting Exported Excel Spreadsheet File

Gregory Schulte (Children's Hospital Colorado) has alerted us that if the "short_open_tag" in the php.ini file of a server (of this web client plugin) is NOT set to* "on*", then the resulting exported Excel spreadsheet may be just a blank file.

He also suggested the following alternatives as workaround options (for those who have encountered this "blank file" problem, else one need not do anything):

  • either change the "short_open_tag" in the php.ini file
          to 
                     short_open_tag = On
  • or change line 15 of the SaveToExcel.php file,
          from 
                     <body><?=$_REQUEST['datatodisplay']?>
          to 
                     <body><?php echo $_REQUEST['datatodisplay']?>
     
     
    Of these, we recommend updating the php.ini file.
    BTW, after either change, as Yves Thorrez (Universitair Ziekenhuis Brussel) reminded us, one must clear the browser cache (close & restart browser session) to ensure the change takes effect.
     
    Incidentally, we determined that this caveat exists for v1.0-2.0 of this web client plugin.
     
    We do hope to have an updated SaveToExcel.php file (that takes care of this caveat without requiring the deployers to update their php.ini files) included in the next release of this web client plugin.
