<p>Hi,</p><p> </p><p>Thanks for your post,but my problem is not with undersating those onCreate or onRender.</p><p> </p><p>All i need a way to apply the scripts written by me in rptdesign file into a java code which generated rpt design file by using birt api engine.</p><p> </p><p>I need a class or method where i can place the scripts to get a desired rptdesign file with the java code.</p>

<p>Hi,</p><p> </p><p>Sorry for misunderstanding your initial question. I am no expert writing Java code using the BIRT API, but I was able to add some JavaScript to the onCreate event of a table by using the following three lines of code:</p><p> </p><p> TableHandle table = elementFactory.newTableItem(null, 3, 1, 1, 1); // Create a table
table.setOnCreate("alert('Hi there');"); // Add script to the onCreate event of the table
design.getBody().add(table); // Add the table to the rptdesign</p><p> </p><p>I have attached the full source code.</p><p> </p><p>Hope this helps,</p><p> </p><p>P.

<p>Hi,</p><p> </p><p>Thank you very much for the code. It helped me a lot.</p><p> </p><p>I just want to get some more doubts clarified. All i need is to put a note or legend in master page footer,can you help me in writing scripts for that.</p><p> </p><p>My requirement is like this.</p><p> </p><p><strong>Page 1</strong></p><p>
</p><p><strong>Table</strong></p><p>Name Value</p><p>A 99</p><p>B 10p</p><p>C 100e</p><p>D 88</p><p><strong>Footer</strong>:</p><p>e - means excellent</p><p>p - means poor</p><p>
</p><p> </p><p> </p><p><strong>Page 2</strong></p><p>
</p><p><strong>Table</strong></p><p>Name Value</p><p>E 99</p><p>F 10</p><p>G 100e</p><p>H 88</p><p><strong>Footer</strong>:</p><p>e - means excellent </p><p> </p><p>
</p><p> </p><p>Here based on the content of the page I should show only the foot notes which are present in that particular page as shown above.</p><p> </p><p>Please help me to achieve this. I had tried setting variable and adding page variables in the master page footer,but it had not worked as I expected. Please ask me if you have not understood my question. If you can send me a sample rptdesign it would be helpful for me. </p><p> </p><p>Thanks,</p><p>Ravi.</p>

<p>Hi,</p><p> </p><p>Attached is a report design that should work for your case. It's using Page Variables and some scripting to dynamically create a footer based on data in the table.</p><p> </p><p>I am using Classic Models to display CUSTOMERNUMBER, CUSTOMERNAME and COUNTRY. For countries UK and USA, I display a legend in the footer, only if these 2 countries are shown on the page.</p><p> </p><p>The two page variables, <strong>isUSA </strong>and <strong>isUK </strong>are initialized on the <strong>onPageStart </strong>event of the report. On the <strong>onPageBreak </strong>event of data item COUNTRY, I set the value of the page variables if the value of COUNTRY is either USA or UK.</p><p> </p><p>On the footer of the master page, I display the two page variables in a grid.</p><p> </p><p>The example is a bit rough and could probably be improved, but it should give a good start.</p><p> </p><p>P.</p>

<p>Hi,</p><p> </p><p>I had tried this approach before. but If you notice it closely,the data is not reflecting from the page.</p><p> </p><p>The page is not showing data in first page even it contains USA. Is this same on your end also?</p><p> </p><p>Page 1 has USA but it is not showing it in the footer. Instead default value false is getting displayed.</p><p> </p><p>Page 2 the previously added USA from page 1 is getting printed in Page 2 footer.</p><p> </p><p>Thanks,</p><p>Ravi.</p>

<p>Which version of BIRT are you using? I have attached a PDF output of the design I sent you and you can see it works perfectly.</p><p> </p><p>Strange...</p>
ravi11
<p>Hi,</p><p> </p><p>May be the version is the problem in this case. I am using Eclipse BIRT Designer Version 4.2.2.v201301221637</p><p> </p><p>Thanks,</p><p>Ravi</p>

<p>I get it. You are probably outputting directly to PDF, aren't you? When I generate the report directly to PDF, the footers are not updated correctly; they are one page behind, like you are describing. However, if I generate to the BIRT Web Viewer, it works fine. And if I generate the PDF from the BIRT Viewer, it is fine as well.</p><p> </p><p>Can you test on your side?</p>

<p>Hi pricher,</p><p> </p><p>Yes I am generating pdf directly in eclipse run as pdf. I tried updating eclipse to luna and kelper as well. I also changed the version of BIRT to latest one,but nothing worked for me. Can you please help me in resolving this issue. How to generate in BIRT Web Viewer?</p><p> </p><p>Thanks,</p><p>Ravi.</p>

<p>Hi pricher,</p><p> </p><p>Thanks for your reply,yes its working in run as birt viewer. I had seen this in using Birt viewer toolkit. But I need it to run in pdf file as well.</p><p> </p><p>Please help me in this.</p><p> </p><p>Thanks,</p><p>Ravi.</p>

<p>Hi Ravi,</p><p> </p><p>I'm afraid this looks like a bug in the PDF emitter. I cannot be of much more help at this point.</p><p> </p><p>P.</p>

<p>One thing I would like to add: In my tests, outputting directly to PDF works fine using the runtime BIRT Viewer or BIRT Viewer Toolkit. In other words, if I use the following URL:</p><p> </p><p><a data-ipb='nomediaparse' href='
http://localhost:8700/birt/frameset?__report=report/Dynamic Footer.rptdesign&__format=pdf'>http://localhost:8700/birt/frameset?__report=report/Dynamic Footer.rptdesign&__format=pdf</a></p><p> </p><p>it
works fine.</p><p> </p><p>P.</p>

<p>Hi pricher,</p><p> </p><p>Yes the url you sent is working but that doesnt fullfill my requirement as I am trying to get the pdf as output by using PDFRenderOption class.</p><p> </p><p>Please help me. Is there any way to get the desired output without using Birt report Viewer. If not possible can you help me how I can add Birt report Viewer in to my project?</p><p> </p><p>Thanks,</p><p>Ravi.</p>
