It is my understanding that isRemoveLineWhenBlank avoids printing a line when there's actually nothing on it, e.g. I have 2 address lines, address1 and address2, followed by city, state and zip on one line. If address2 is blank, city, state, zip will be printed immediately under address1, without leaving the vertical space for address2.

It is a very useful feature, saving quite a few printWhenExpressions. Any forecasts as to its availability :-)

Hi,

 

The "isRemoveLineWhenBlank" attribute and the

others are now implemented in the 0.4.0 version.

 

Thank you,

Teodor

I'm trying to use the new isRemoveLineWhenBlank attribute without success. Here is the code snippet for the report definition:

 

<detail>

<band height="130">

<textField isBlankWhenNull="true">

<reportElement x="0" y="35" width="350" height="15"

isRemoveLineWhenBlank="true" positionType="Float"/>

<textElement textAlignment="Left"/>

<textFieldExpression class="java.lang.String">

$F{line1}

</textFieldExpression>

</textField>

<textField isBlankWhenNull="true">

<reportElement x="0" y="50" width="350" height="15"

isRemoveLineWhenBlank="true" positionType="Float"/>

<textElement textAlignment="Left"/>

<textFieldExpression class="java.lang.String">

$F{line2}

</textFieldExpression>

</textField>

<textField isBlankWhenNull="true">

<reportElement x="0" y="65" width="350" height="15"

isRemoveLineWhenBlank="true" positionType="Float"/>

<textElement textAlignment="Left"/>

<textFieldExpression class="java.lang.String">

$F{city}+", "+$F{state}+" "+$F{zip}

</textFieldExpression>

</textField>

</band>

</detail>

 

The $F{line2} is blank in the data I pull from the datasource, however, it is still being displayed as a blank line on the report output as follows:

 

John Smith

 

Noble, IL 99999

 

Thoughts on what I'm doing wrong?

Hi,

 

Make sure the text field that you want to disappear

does not share vertical space with any other

element.

The most probable cause is that you have maybe

a rectangle around the text fields or some vertical

lines on the sideways.

 

The vertical space collapses only

when "isRemoveLineWhenBlank" elements are

the only elements present in the given vertical

space.

 

I hope this helps.
