Evgeny commented on CAMEL-16402:
--------------------------------
I'm a new in camel apache and before worked as back-end developer.
With programming languages like C/C++, C# alway could get info about ara of
visibility for variables.
For current problem I coudn't find info.
A have some suggestion about this already.
May you tell me about headers area of visibility, please. It will strongly help
me with camel in future.

> When I reading csv files in split, I need to get get field names and
> calculate index for each name. It's OK via groovy.
> I try to store indexes in some heades. I need it because csv file coud
> contain fields in arbitrary order.
> In one file: name, ID, address...
> In other file: ID, address, name...
> <when>
> <simple>${headers[CamelSplitIndex]} == 0</simple>
> <transform>
> <groovy>
> <![CDATA[
> String[] AllData = exchange.getIn().getBody().split(';');
> //some processing
> //and store to headers for next using
> //for case name, ID, address...
> exchange.getIn().getHeaders().put("Name", NameValue); //0
> exchange.getIn().getHeaders().put("ID", IDValue); //1
> exchange.getIn().getHeaders().put("Address", AddressValue); //2
> ]]>
> </groovy>
> </transform>
> I use index for each field, to get correct value when I going to insert in
> database.
> But each time split (new step) read new line from csv file, headers a lost
> their value.
> While ${headers[CamelSplitIndex]} == 0 headers contain fields index.
> But when ${headers[CamelSplitIndex]} > 0 all headers loose the info.
> How to create real global variables, which will be avialable in any <when>
> cases and slplit steps?
