Evaluating fields within fields

2002-12-06 01:11

I am displaying a field from my database and wish to insert another field into this filed e.g.

 

<textField evaluationTime="Page">

<reportElement positionType="Float" x="0" y="160" width="523" height="250"/>

<textElement textAlignment="Justified"/>

<textFieldExpression class="java.lang.String"><![CDATA[$F{PARAGRAPH}]]></textFieldExpression>

</textField>

 

filed $F{PARAGRAPH} is a text field and contains $F{PRODUCT} - I can't seem to get JasperReports to evaluate the inner field PRODUCTS.

 

Any Help Please

Hi,

 

Field values cannot contain field references.

This is also true for parameters and variables.

 

There is no recursive evaluation of expressions.

You have to find another way to obtain what

you want.

 

Thank you,

Teodor
