How to avoid print footer in last page of JasperReport? [duplicate] - jasper-reports

Question

I need to enable the reports with 3 types of the page headers: "first page header", "middle pages header" and "last page header". All of these headers can have different number of report elements and on different positions. Same goes for the footers.
NOTE: The report must support the report elements like jr:table or jr:list in its Detail band. These element must be supplied with the data via xml datasources.
I was able to simulate first page header by using Title band, but I'm having problems enabling "middle pages header" and "last page header". This is what I'm trying to do:
<pageHeader>
<band height="100" splitType="Stretch">
<frame>
<reportElement x="0" y="0" height="100" width="555" uuid="f788c74b-6853-4bc7-8ed7-5e3d538287c9" isRemoveLineWhenBlank="true">
<printWhenExpression>
<![CDATA[new Boolean($V{PAGE_NUMBER} == $V{PAGE_COUNT})]]>
</printWhenExpression>
</reportElement>
<staticText>
<reportElement x="1" y="1" width="100" height="20" uuid="9777208b-5323-4045-aa49-a849d5c00c89"/>
<text><![CDATA[LAST PAGE HEADER TEXT 1]]></text>
</staticText>
<staticText>
<reportElement x="50" y="10" width="200" height="50" uuid="15313676-09e6-4d17-ac75-2df99f61bfee"/>
<text><![CDATA[LAST PAGE HEADER TEXT 2]]></text>
</staticText>
</frame>
<frame>
<reportElement x="0" y="0" height="100" width="555" uuid="65577abd-8717-477a-f27e-c70e9eba46af" isRemoveLineWhenBlank="true">
<printWhenExpression>
<![CDATA[new Boolean($V{PAGE_NUMBER} != 1) && new Boolean($V{PAGE_NUMBER} != $V{PAGE_COUNT})]]>
</printWhenExpression>
</reportElement>
<staticText>
<reportElement x="70" y="0" width="300" height="100" uuid="0a866eb3-85cf-4376-d6a4-21b534d36df0"/>
<text><![CDATA[MIDDLE PAGE HEADER TEXT 1]]></text>
</staticText>
</frame>
</band>
</pageHeader>
I'm using frame blocks along with printWhenExpression. Depending on the printWhenExpression condition, only one of two frame blocks should be printed (with all of its content). First frame block should render "last page header", and second one should render "middle pages header".
The problem lies within the first frame ("last page header") printWhenExpression:
<printWhenExpression>
<![CDATA[new Boolean($V{PAGE_NUMBER} == $V{PAGE_COUNT})]]>
</printWhenExpression>
In this case, $V{PAGE_NUMBER} always equals $V{PAGE_COUNT} because of the evaluation time.
Is there any way to check if the current page is the last page? Also, is there any other way to enable "middle pages" and "last page" headers?
NOTE: I was able to implement similar logic for the footers by using the frames and Last Page Footer band!

Answer 1

First of all: $V{PAGE_COUNT} is
the number of records that were processed when generating the current page. Hence the number of records you have in the page, not a page number count...
In pageFooter and lastPageFooter the reportElement can have negative Y coordinates (if IDE does not allow this then you need to edit manually the jrxml) es. y="-700", which allows you to put information in pageHeader and last pageHeader...
FIRST PAGE
in frame use:
<printWhenExpression><![CDATA[new Boolean($V{PAGE_NUMBER}.intValue()==1)]]></printWhenExpression>
pageHeader use title band or put frame in pageFooter and use negative y coordinate.
pageFooter, use pageFooter band
MIDDLE PAGE
on frame use:
<printWhenExpression><![CDATA[new Boolean($V{PAGE_NUMBER}.intValue()>1)]]></printWhenExpression>
pageHeader put frame in pageFooter and use negative y coordinate.
pageFooter, use pageFooter band.
LAST PAGE
pageHeader, put frame in lastPageFooter and use negative y coordinate.
pageFooter, use lastPageFooter band
NOTE: To generate space for this virtual pageHeader include an empty pageHeader with desired band height
