Hi all...I was reading the spec for the text element
(http://www.eclipse.org/birt/ref/ROM_Text_SPEC.pdf) and in section 5.1 it
says:
The value-of tag identifies a value to insert into the text for a Text
element. The value-of
tag contains the expression to evaluate to obtain the data. Value-of tags
cannot be
inserted into text returned from the value expression property (i.e., it
can not be used
with data and multi-line data items).
For example:
Dear <value-of>
if [Sex] = M then Mr.
else if [Sex] = F then Ms.
</value-of> <value-of>row.firstName</value-of>
<value-of>row.lastName</value-of >,
<p>
<b>Thank you</b> for your purchase of an exciting new
<value-of> row.productName</value-of > on
<value-of> row.purchaseDate</value-of>.
The above shows that the value-of tag can encapsulate either a simple
value/expression, or a script.
My question is: what does the bracketed expression mean (if [Sex] = M
then Mr.)? What object/value does this use? (I understand brackets to
get script object properties or array elements, but this doesn't look like
either of those.)

This spec was written before the implementation was fully decided. You must
use a valid JavaScript expression. I was unable to get the if, then, else
syntax to perform, so I checked the JavaScript documentation for valid
expression formats. After doing that, I successfully used the following:
<VALUE-OF>(row["custID"] > 200) ? row["Issues"] : "Customer level does not
permit an issue" </VALUE-OF>
I am using the 2.0 stable build 20051110.
