[need help for subreport issue: variables cannot compute based on return value of subreport]

I check it again, I found return value cannot evaluate in this band, but will work for next entry/band, thus, every entry varaible value is not correct!.

 

 

[(Return) Variables and evaluation time]

very sorry to hear that, I encounter same problem now, I also want to know how to caculate based on sbureport return value.

[need help for subreport issue: variables cannot compute based on return value of subreport]

I am using jsper studio 5.6, I use cherry group report, and use subreport in group to get another table field info,

I set variable_1 as return value of subreport, I can display it when I set evaluation time=band.

then I define a variables named   V1= $F{field}- varables_1,  I found it always return null.

if I directly input above expression in a text field and set evaluatoin time=band , it works!

What's the reason?

since I need sum(V1) in group, I have to use V1 instead of text field.

what I should do?  is it a bug? or is there any propertity I can set?

[need help: how can I pass table field value to subreport?]

I am using table and tableDataset in report, now I place subreport on table field row, hope subreport can get table field value as parameter to query data.

but I found subreport can only accept main report field/paramters,  not table fields/variables,

how to to resolve it ? 

if jasper do not support it, I have to give up table component, only use main report.

thanks!

[Passing values from subreport to a table dataset in iReport]

I have similar question, how to pass table field value to subreport as parameters, I found subreport only read main report parameters and fields, not table elements.

 

[Urgent:run scriptlet to return - document is empty]

eferrell, thank you very much.

I add a simple query for main report ,and it works!

aanyway ,thank you very much.

 

 

 

 

[how can I save report variables value to database?]

I found sctiptlet code at demo folder. and think it's good idea to write back db.

[Urgent:run scriptlet to return - document is empty]

HI,  I am using scriptlet in jasper studio, I do following steps:

1. copy demo scriptlet java code to netbean project to build  a jar file.

2. add jar file to jasper studio  java build path (add external jar to studio project java build path)

3. create a new simple report with static text and text fileds.

3. add script class for report properties,

4. define $P{report_scriptlet}  properities with script class.

then I copy demo code-  set text filed expression -->    $P{report_scriptlet}.hello()

then I run it in studio , it return me "document is empty!"  what that mean?

I am sure now studio can found my scriptlet, since compile is fine , and console return message :

Start Report Execution
Compiling report......DONE
Setting Data Adapter...DONE
Setting Virtualizer...DONE
Filling Report........DONE
Report Execution Finished.

 

any help is appreciated!

 

 

 

 

[days function does not work when integrate with web java code]

I have to add my update info:

I  I changed report language to groovy from java, and add groovy class into classpath, now it return me :

net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression :
    Source text : ABS($F{QUANTITY})

it seems that I canno use any build-in fuctions in japer studio, inlcude:  IF-else, ABS, Days.

I found it's becuase there is no jasper mathfuction class. I search all folder, found there have classes at sample folder, I add them, then pass!

conclusion: I do not know why jasper do no package mathfunction into jasper lib, but, if you want to use it, you have to include it mannualy.

 

 

 

 

 

[days function does not work when integrate with web java code]

HI, I am using jasper5.6.1 in win7,jdk1.7, I use days function in studio to calculate date diff between min_date and max_date, such as :

days($V{min_date},$V{max_date})

it works fine in studio, but when I called it from web java application, it always return me following error:

net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression :
    Source text : DAYS($V{min_date},$V{max_date})

I also encountered another IF experession error,

 

I doubt it's java issue, and I check my report language setting, it's "JAVA".

if I cannnot use system function, I have to pass all calculated varibles from outside application, it's too complex.

could you give me some suggesiton? thanks!
