[Table missing first record using IWSDataSource]

I guess in your case you can use JREmptyDataSource for main report and use JSON DataSource as parameter of main report.

 Probably first record in table will not missing.

[Tutorial for using Nested JavaBeans]

You can use subreport

In main report define field corresponding getter for nested bean collection.
For example

public class MyBean() {

private List<MyNestedBean> mysuperpuperNestedBeans;

private Long id;

public Long getId() {

return id;

}

public List<MyNestedBean> getNestedBeans() {
     return mysuperpuperNestedBeans;
}

}

 

 

public class MyNestedBean() {

private String firstStringField;

public String getFirstStringField() {

return firstStringField;

}

}


in jrxml define fields
$F{id} with type Long
$F{nestedBeans} with type java.util.Collectioin  (name of field corresponds getter getNestedBeans)

make subreport in detail band of main report
Define in main jrxml DataSourceExpression for subreport like this

new JRBeanCollectionDataSource($F{nestedBeans})

define fields in subreport corresponding getters in MyNestedBean class

for example $F{firstStringField} with type java.lang.String

Not anough info to give advice
show full stacktrace and show values for $P{DateForm2} and $P{BegingStringToDate}

[Subreport rendering]

subreport = templateUtil.getJasperSubReportTemplate( reportName )

so subreport is not path

[Subreport not working with JavaBeans Collection datasource.]

I see  $P{REPORT_CONNECTION}  but not "JavaBeans Collection as datasource"

Try to ask correct question

[Do not send a scheduled report if there is no data]

Set at report properties whenNoDataType="AllSectionsNoDetail". You will get empty report in this case.

>>But I do not want to come empty report
I guess it is bad idea. You can't understand when your report is empty or when it is broken (error?)

[subreport not executed when in detail band if detail band 'print when' is false]

You can set Height = 0 px at properties of detail band  (properties -> appearence)

[subreport not executed when in detail band if detail band 'print when' is false]

>>If I set the 'print when' value of the detail band to false, the subreport in the detail band is not started
Yes, jasper will not execute subreport in this case.

Strange desire to put subreport into detail band if subreport is not depend on data of detail band.
For example if your report contain 2 records in detail band then subreport will executed twice.
I can't understand idea (aim) to execute subreport in detail band

You can put subreport into summary band.

[where to put my parameter?]

Question was:
>>where I shouls put my parameters? in master or subreport ?

In example
http://community.jaspersoft.com/wiki/subreports

field $F{ID} passed from main report to parameter $P{ID_PERSON} of subreport

You can pass param into main report.  Fro example $P{myParam1} from your application
After that you can pass $P{myParam1} from main report to subreport

There are no fundamental deffirences between pass field or parameter of main report to subreport.
I can't understand your problem (or doubt?). You got enouph information to solve your problem.
Just do it.

Good luck

[Hiding columns in jrxml]

Good example to show columnPrintWhenExpression

but
!$P{EMPLOYEEID}.equals(null)    -  it is nonsense (imho)

It always true when $P{EMPLOYEEID} != null
It cause NPE when $P{EMPLOYEEID} == null

To topicstarter:
Discussion without your code (description of condition on column) is not efficient.
Show jrxml and describe condition which you want 

[Hiding columns in jrxml]

You can use Table component and set printWhenExpression on column of table

[where to put my parameter?]

You should put parameters to main report and then pass it from main report to subreport

[number format not working]

It is a "feature" of Studio.

Since one version (i don't remember which one) all fields (textfields?) created as String.

Sometimes it work fine. Sometimes problems suddenly appear a problrms. Be careful.

[number format not working]

class="java.lang.String" ?
Which result when it changed to java.lang.Double ?
 

[How to display different values with the same $F{field} name]

Add another field from table evaluation into report to check the result of execution sql-query
And show jrxml and result of execution.
It is so hard to undestand error (in report? in query? in textfield?) without jrxml...
For instance you wrote that count of record from sql-query=3
But in screen presents only 2 records:
tewlawte
tewlawte

Why?

 

[Crosstab : "Blank if null" not works with a total average]

You can realize incrementer on java which return null (or your own specific object in terms of java) instead zero

http://www.jasperreports.sourceforge.net/api/net/sf/jasperreports/engine/fill/JRExtendedIncrementer.html
http://www.jasperreports.sourceforge.net/api/net/sf/jasperreports/engine/fill/JRExtendedIncrementerFactory.html

But...
There are few information about realization of such classes in internet and documentation
And this way not for newbies imho

I guess you have choose the easier way. For example you can calculate count not null values on column (row?) of crosstab and hide sum variable if this count = 0
see here http://www.stackoverflow.com/questions/23473887/count-number-of-rows-where-a-field-is-a-specific-value/23491357
