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. On Mar 22, 2012, at 12:15 PM, Greg Von Kuster wrote:
It's always best to look at examples in the code base for technical details like this rather than the wiki. You probably will need a combination of a <conditional> constructor along with a select list item in your tooll There are many tools that include these types of constructors that refresh the page when a <when> condition is met. One example is the extract_genomic_dna.xml tool config, which includes the following tag sets.
<inputs> <param format="interval,gff" name="input" type="data" label="Fetch sequences for intervals in"/> <param name="interpret_features" type="select" label="Interpret features when possible" help="Only meaningful for GFF, GTF datasets."> <option value="yes">Yes</option> <option value="no">No</option> </param> <conditional name="seq_source"> <param name="index_source" type="select" label="Source for Genomic Data"> <option value="cached">Locally cached</option> <option value="history">History</option> </param> <when value="cached"> </when> <when value="history"> <param name="ref_file" type="data" format="fasta" label="Using reference file" /> </when> </conditional> <param name="out_format" type="select" label="Output data type"> <option value="fasta">FASTA</option> <option value="interval">Interval</option> </param> </inputs>
Sorry, but I don't have the time to get too much more involved in this than I have - as always, I'm stretched as thin as can be. Good luck!

Leandro,
For refresh_on_change to work you need a set of optional selections and a set of refresh_on_change values, so in your example, the type should probably be a select instead of data. You'll also need the select list options to be generated based on your history items (at least that's what I think you're attempt here), so your list of refresh_on_change values will be attributes of those history items.

Could you show an example of this functionality that you described? This is new to me I really apologize and I looked for things on the Galaxy wiki but couldn't find. How would one do the simple example I illustrated in this thread:
<inputs> <param type="data" format="txt" name="dataset" label="Select a text file from you history" /> <param type="select" multiple="true" name="dataset_values" dynamic_options="get_options_from_file(dataset.file_name)" /> </inputs>
Where in the tool form if the user changes the first drop-down menu to select a different file of a particular format from their history it will cause a refresh of the page so that the dynamic_options function in the second menu can be re-executed using the new file name as a parameter then generating new options in this second menu?

Here's one example:
<inputs>
<param type="data" name="dataset" refresh_on_change="true"
label="Select a file from you history" />
<param type="select" multiple="true" name="dataset_values"
dynamic_options="get_options_from_file(dataset.file_name)" />
</inputs>
If the user changes their selection of data from their history it
should refresh the page and call the dynamic options again to load the
other select menu with the choices from the new file. Currently you
have to do this with repeat or pages tags which is really cumbersome
for the user in the UI or doesn't allow workflowing, respectively.
Page should refresh automatically when dataset is changed and dynamic
options are used. If not, it's a bug.
Ok, not sure what this means, the above example I wrote doesn't work so is this a bug or is there another way to write the above example so that it will work?
