Hello,
I am searching for the best way to do the following:
I want to iterate about my beans and use an excel template.
Map<String, _Collection_> beans = *new*HashMap<String,
_Collection_>();
// ..
beans.put("nutzer", nutzer);
XLSTransformer transformer = *new*XLSTransformer();
transformer.transformXLS(/templateFileName/, beans, outputFileName);
Each item of the collection nutzershould be in a new row.
<jx:forEach items="${nutzer}" var="n">
Text | ${n.getName()} | .... | ..
</jx:forEach>
Every item 'n' contains another collection 'coll'. I do not know the
number of item in 'coll' at compile time, but I want to have each item
in a new columm.
<jx:forEach items="${nutzer}" var="n">
Text | ${n.getName()} | .... | <jx:forEach items="${ ???}" var="zelle">
| ${zelle} | </jx:forEach>
</jx:forEach>
My problem is to find the correct expression in the inner forEach.
I have an method called 'calcColl' which returns a Collection<String>,
but it is not allowed to write
<jx:forEach items="${ n.calcColl()}" var="zelle">, isn't it ?
Next try :
I created a private field 'coll' and a 'getColl()' method :
*public*Collection<String> getColl(){
coll= calcColl();
*return*coll;
}
And wrote :
<jx:forEach items="${ n.coll}" var="zelle">
But this also did not work. Now I am confused, because if I instantiate
'coll' in the constructor with data and use
*public*Collection<String> getColl(){
*return*coll;
}
everything is fine. Unfortunately I have to calculate 'coll' at a later
time.
What am I doing wrong ?
Best regards and thanks for the great library
Florian
