Hi All, I’m trying to implement a tool that get a list of options through the “dynamic_options” tag. I try to filter the options that get returned with another param, but it doensn’t seem to work. my tool xml looks like this <tool id="archivetolibrary" name="Copy files" version="0.1.0"> <description>from the archive to a data library</description> <code file="list_files.py"/> <command interpreter="bash"> test.sh > $log </command> <inputs> <param name="archive_source" type="select" display="radio" label="Choose source archive"> <options from_file="archives.loc"> <column name="name" index="0"/> <column name="value" index="1"/> </options> </param> <param name="query" type="text" label="Search for files"/> <param name="selected_file" type="select" label="Choose your file" dynamic_options="list_files(archive_source)"> <filter type="param_value" ref="query" column="0" /> </param> </inputs> <outputs> <data name="log" format="txt" label="${tool.name} on ${on_string}"></data> </outputs> <tests> <test> </test> </tests> <help> </help> </tool> Anyone with experience implementing filters?
