New subject: refresh_on_change is broken?

6 May 2012


      Hi,
The Extract GFF Features doesn't use dynamic options and I don't think that's really the question here.
Let me give an example of something that I do. I have the user select a file after which I, using dynamic_options, extract the column names and present those to the user with a select input parameter. With the selected column name I then present a new select input parameter with all the unique values of the selected column.
To get this to work I am now using three pages since it is really dynamic, thus after each parameter (that uses dynamic_options) I need to make a new page to use the selected item, thus:
<page>
          <param name="input_dataset" type="data" format="tabular, txt" label="Input dataset" />
      </page>
      <page>
          <param name="colfilter" type="select" multiple="False" label="Select Filtering Column"
                 dynamic_options="get_columns( input_dataset )" />
      </page>
      <page>
          <param name="filter_values" type="select" multiple="True" label="Select Filtering Values"
                 dynamic_options="get_filter( input_dataset, colfilter, 2 )" />
      </page>
      ....
This works fine, however it requires three pages which is deprecated. The documentation says 'use refresh_on_change' which is an undocumented feature (please (please!!) fix this!) with no examples anywhere on how to replace common <page> usage. So given above example (which is similar to what the original requester asked), where to place the refresh_on_change option to get it working?
I've of course tried to place it within both dynamic_option parameters but this doesn't update the 'filter_values' parameter depending on the 'colfilter' parameter..
Kind regards,
Marcel

A final pointer: to see tools that use dynamic options, take a look at "Extract GFF features" and "Filter GFF dataset by feature count"
Good luck,
J.
