Whenever you submit a form to download a file the response sent back is a file. In this case the setter called after the method which does the download has no effect.<\/p>\n
\r\n if(form.getDownloadForm != null && form.getDownloadForm.equals("Y"))\r\n {\r\n downloadForm(form, request);\r\n\r\n \/\/The Below Setter has No Effect\r\n form.setDownloadForm("Y");\r\n }\r\n<\/pre>\n\r\n class RegisterForm()\r\n {\r\n public String downloadForm;\r\n\r\n public void setDownloadForm(String p_download) \r\n {\r\n\t this.downloadForm= p_download;\r\n }\r\n \r\n public String getDownloadForm() \r\n {\r\n\t return downloadForm;\r\n }\r\n } \r\n<\/pre>\nThe Setter had no effect since the request sent to the downloadForm(form, request);<\/strong> will end up with response of file download and not response which has new values to form set by setter(in our case downloadForm(form, request)<\/em>) and Page reload.<\/p>\nThere are 2 simple fix for this. <\/p>\n
Fix 1<\/strong>
\nOne simple fix is to set form hidden property in java script to N after the form get submitted. Note though the form is submitted it is not reloaded with new response since the response sent back is a file.<\/p>\nThe Page will be reloaded only when response is sent back to the same URL of browser. Not to the browser as file.<\/strong><\/p>\n\r\n function downloadWFSetup(pWaterfallId) \r\n {\t\r\n $('#downloadForm').val('Y');\r\n document.WaterfallTriggerForm.submit();\r\n\r\n \/\/This part of code runs even after the form submission since the \r\n \/\/response sent is file which does not require page reload\r\n $('#downloadForm').val('N');\t\t\t\r\n }\r\n<\/pre>\nIn our case the page is not going to get reloaded so the java script continues its execution even after form submission setting property of downloadForm<\/strong> to N<\/strong>.<\/p>\nFix 2<\/strong>
\nThe Other way is to send request in Link with downloadForm=Y<\/strong>. In this case there is no need to to reset the form values as we get the values by request.getParameter()<\/strong> Method.<\/p>\n","protected":false},"excerpt":{"rendered":"Whenever you submit a form to download a file the response sent back is a file.
