> Hi,
> There is an issue with the ExtractText processor, in the attempt of creating
> FlowFile attributes from FlowFile contents.
> When creating a custom property with a regex value that does not contain
> named groups, the value captured in the group is added as 2 different
> attributes.
> E.G.
> ||Property Name||Property Value||Expected FlowFile Attribute||Actual outcome||
> |param.alpha|<regex for alpha>|param.alpha=alpha|param.alpha=alpha
> param.alpha.1=alpha|
> Reading the documentation, this might even be an expected behaviour, but if
> so, it is preferable to have the captured value only as a single attribute,
> without duplication.
> Please see the attachment for an example.
