Hi, I have a tool where the input is multi-select of datasets, e.g.:
<param type="data" multiple="true" name="input1" /> I tested it to see what it would pass to my command and I get the following debug page and error in Galaxy: AttributeError: 'list' object has no attribute 'missing_meta' The last part of the stack trace looks like: >> validator.validate( value, history ) Module galaxy.tools.parameters.validation:185 in validate history <galaxy.model.History object at 0xb8ea190> self <galaxy.tools.parameters.validation.MetadataValidator object at 0xb8e6250> value [<galaxy.model.HistoryDatasetAssociation object at 0xa255550>, <galaxy.model.HistoryDataset ... Association object at 0xb8ea210>] >> if value and value.missing_meta( check = self.check, skip = self.skip ): AttributeError: 'list' object has no attribute 'missing_meta' What am I doing wrong? regards, Leandro
