Problem Description: after performing a submit to an action which sets the HttpServletResponse to download a file, the file downloads, however the page on which the action was initiated does not allow any of its buttons to gain focus, thus I am unable to click them. If I refresh the page via the browser button, the buttons are able to gain focus, however if I code the refresh using javascript then the page refreshes without performing the download.
Here is the code from my action:
byte[] byteArray = call to method which returns a byteArray
response.reset();
response.setContentType("application/x-msdownload");
response.addHeader("Content-Disposition","attachment; filename=\"" + new String(fileName.getBytes())+ "\"");
ServletOutputStream output = null;
try{
output = response.getOutputStream();
output.write(byteArray);
output.flush();
}
catch(Exception e){
_logger.error(e, e);
}
finally{
output.close();
}
Here is the JSP code:
<input class="portlet-form-button" type="button" value="Export" onClick='updateParamStrings(); submitForm(document.communityEditForm, "<portlet:actionURL windowState="<%=LiferayWindowState.EXCLUSIVE.toString()%>"><portlet:param name="struts_action" value="/community_register/communityedit"/><portlet:param name="method" value="export"/></portlet:actionURL>");'>
I have also tried adding "return false" at the end of the onClick event chain. No result.
Any advice, help, criticisms would be greatly appreciated
Thank you
