All the syntax options you mentioned should work.
Please share your classes so that we can take a look.
Or sent me an example demonstrating the problem.

| 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 nutzer should 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(); returncoll; } 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(){ returncoll; } 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 |
