Description

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?
