Referencing blocks and fields in blocks

Block reference

A reference to a block in a Message is defined using the following syntax:

$message.<blockName>[<blkInstance>]

For example, if you want to reference the third instance of the block blkA you must define this reference as $message.blkA[2] in the template.

Note:

Block instances are zero based which means the first instance of a block is [0].

Reference to fields in blocks

A reference to a field in a block is defined using the following syntax:

$message.<blockName>[<blkInstance>].<fieldName>

For example, if you want to reference the field description in the third instance of the block blkA you must define this reference as $message.blkA[2].description in the template.

Reference to a sub-block

A reference to a sub-block is defined using the following syntax:

$message.<blockName>[<blkInstance>].<blockName>[<blkInstance>]

For example, if you want to reference the first instance of the block blk4 in the third instance of the block blkA you must define this reference as $message.blkA[2].blk4[0] in the template.
