@hozawa, that was near what I need, but not exactly... I verify that it's possible to use this getUUID() from uncompiled "jrxml" files, but not "on-the-fly". What I want is to pick an element within a scriptlet, using its UUID (or its key), to change its attributes based on data beeing processed. But I guess it is not possible...

Hi friends! Every report we mount with Jasper Studio includes UUID numbers for every element. It will be very useful, if I can retrieve these elements using the generated UUID, but... is it possible? I would like to retrieve an element in a JRElement (for instance), inside a scriptlet, to manipulate it... But I could not find any method or example in that way, like: "JRElement jre = reportResource.findByUUID(<UUID>);" or something... If it's impossible to do such a thing, why this UUID attribute exists?

I could not believe Jasper Reports could not do such a common thing! There must be some alternatives... Perhaps some event control that I could capture the control during report generation and adjust detail band height of last report page, according with used space or height of page header band...

Hi guys! I’m new in Jasper Reports, so my problem may be easy for you, but is hard to me! I have a more complex report, but I create a new one, almost-empty, to exemplify it. In this example, I have two bands, the page header band and the details band. Inside the details band I put a frame, with a border all-around it. My page header band can stretch, depending on the growth of data inside it. I need that page header first grows as it needs, AND THAN detail band grows FOR THE REST OF THE PAGE. I tried to let detail band lower than the space for A4 paper, but it will stretch only if data inside of it requires, but I need that it grows ALLWAYS… So, I tried to pull it manually, during design-time, but than the header band could not grow, because there’s no space to do it (detail band does not “shrink” back if space is not used)… Someone have any idea?
