I am using the Download datasubset plugin for generating download link of Excel

@chetany Hi, the actual issue related to name is, the plugin is failing to search or parse the rule, when the rule's name starts with a number and that's what my findings conclude. So you could go ahead with including underscores, but please make a note that your rule doesn't start with a number(s). It's okay even if you have number(s) in the middle.

Here are the technical details related to this feed entry with regards to problem in name of rule that is used to get exportable data subset in fn!getdatasubsetdownloadlinkfromrule():

Line #53 in GetDataSubsetDownloadLinkFromRule.java is throwing an array index out of bounds exception

Content asContent = cs.searchByRoot(baseId, ruleName, new ContentFilter(ContentConstants.TYPE_NON_DOCUMENT))[0];

The API function 'searchByRoot' in ContentService interface accepts the rule name (after making a conversion on it) passed by us as a parameter and a regex of type text is the type of input. Not sure if this is failing to accept the text that starts with number.

Logs:

Hope the above helps those who faces similar issue or tend to look at the plugin code to solve if it is an issue really.
