How to use table component added to JasperReports 3.7.2 with grails jasper plugins? -

-

i use new table component added jasperreports 3.7.2 grails jasper plugins. find new component useful generate tables.

i have define table dataset 1, , fields (ex : $f{name}), problem, fields values null. have define fields (not attached table), , values.

here table code :

<subdataset name="table dataset 1">     <field name="name" class="java.lang.string"/>     <field name="signal" class="java.lang.double"/>     ... </subdataset>  <componentelement> <reportelement key="table" style="table" x="0" y="0" width="802" height="50"/> <jr:table xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemalocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd"> <datasetrun subdataset="table dataset 1"> <datasourceexpression><![cdata[new net.sf.jasperreports.engine.jremptydatasource(1)]]></datasourceexpression> </datasetrun> <jr:column width="90"> <jr:columnheader style="table_ch" height="30" rowspan="1"> <statictext> <reportelement x="0" y="0" width="90" height="30"/> <textelement/> <text><![cdata[name]]></text> </statictext> </jr:columnheader> <jr:detailcell style="table_td" height="20" rowspan="1"> <textfield> <reportelement x="0" y="0" width="90" height="20"/> <textelement/> <textfieldexpression class="java.lang.string"><![cdata[$f{name}]]></textfieldexpression> </textfield> </jr:detailcell> </jr:column>     ...

i guess, problem due part (i'm using jremptydatasource) :

<datasourceexpression><![cdata[new net.sf.jasperreports.engine.jremptydatasource(1)]]></datasourceexpression>

but how can <model_data> table component ?
(eg : chain(controller:'jasper',action:'index',model:[data:<model_data>],params:params))

here solution :

keep :

<subdataset name="table dataset 1">     <field name="name" class="java.lang.string"/>     <field name="signal" class="java.lang.double"/>     ... </subdataset>

and use :

<datasourceexpression><![cdata[$p{report_data_source}]]></datasourceexpression>

table component use actual datasource (your model_data) !

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
