Sometimes I get an exception with message "getOutputStream() has already been called".

Controller:

    def index() { 
        render( filename:"File hepp.pdf",
                view:"/foo/index",
                model:[someInstance:"bar"],
                marginLeft:20,
                marginTop:35,
                marginBottom:20,
                marginRight:20,
                headerSpacing:10
        )

    }

view:

<html>
<head>
</head>
<body>
<h1>Hello</h1>
</body>
</html>

Does not happen every time.
Current render method from trait WkhtmltopdfRenderer is:

    void render(Map params) {
        if (params.contentType?.toLowerCase() == 'application/pdf' || response.format == "pdf") {
            def filename = params.remove("filename")

            def data = applicationContext.wkhtmltoxService.makePdf(params)

            response.setHeader("Content-disposition", "attachment; filename=${filename}")
            response.contentType = "application/pdf"
            response.outputStream.write(data)
            response.characterEncoding = 'UTF-8'
            response.setHeader('Cache-Control', 'no-store, no-cache, must-revalidate') //HTTP/1.1
            response.setHeader('Pragma', 'no-cache') // HTTP/1.0
            response.outputStream.flush()

        } else {
            // Defer to original render method
            super.render(params)
        }
    }

The pdf rendering part is more or less untouched from the original Grails 2 version of the plugin.

Controller is rendering not generating PDF

Hi,

Grails 3.0.9
compile "org.grails.plugins:wkhtmltopdf:1.0.0.RC3"
application.yml already has pdf: application/pdf
command line works %> wkhtmltopdf www.google.com myhomepage.pdf

I am trying to generate PDF in controller/action. But it renders the the template rather than generate PDF. If i comment out render() from action it will generate empty PDF.

render( filename:"File bla.pdf",
view:"/salesRep/pdfGenerator",
model:[bla:bla],
header:"",
footer:"",
marginLeft:20,
marginTop:35,
marginBottom:20,
marginRight:20,
headerSpacing:10)

Don't replace the render method in the controller

The plugin will replace the render method if contentType is "application/pdf". I can see how that is useful but how can it be disabled? I already have existing pdfs that need to be served, no need to regenerate them using this plugin.

Replace render method

In Grails 2.x the plugin replaced the original render method on controllers. (see WkhtmltopdfGrailsPlugin.replaceRenderMethod)
This didn't work in Grails 3 due to render method being added by trait (grails.artefact.controller.support.ResponseRenderer)

May be a bug in Groovy, Jeff Scott Brown was surprised by this behavior and opened https://issues.apache.org/jira/browse/GROOVY-7500

Demo request

Hi!

I would really appreciate a working demonstration repo which would showcase the gsp templating and css at the very least. Ideally the demo would work with git clone, ./gradlew bootRun and navigating to http://localhost:8080/example/foo.pdf.

I'm struggling with getting the plugin to work and cannot figure out whether the problems are in my gsp's or perhaps in the incompatible version of wkhtmltopdf binary.

Thanks.

Not able to render font-awesome icons in generated PDFs.

Hi,
We are upgrading our App from Grails 2.5.4 to Grails 3.3.10, in the process we upgraded the version of the plugin from org.grails.plugins:wkhtmltopdf:0.1.11 to org.grails.plugins:wkhtmltopdf:1.0.0.RC9. The Font Awesome icons were rendering just fine in the earlier version of Grails, but not since the upgrade.

Here's a snippet from the CSS file that loads these fonts. any help is appreciated:

@font-face {
font-family: 'FontAwesome';
src: url('../fonts/fontawesome-webfont.eot?v=4.3.0');
src: url('../fonts/fontawesome-webfont.eot?#iefix&v=4.3.0') format('embedded-opentype'), url('../fonts/fontawesome-webfont.woff2?v=4.3.0') format('woff2'), url('../fonts/fontawesome-webfont.woff?v=4.3.0') format('woff'), url('../fonts/fontawesome-webfont.ttf?v=4.3.0') format('truetype'), url('../fonts/fontawesome-webfont.svg?v=4.3.0#fontawesomeregular') format('svg');
font-weight: normal;
font-style: normal;
}

Cannot invoke method getBean() on null object when gsp contains g:select

PDF rendering is failing when the GSP contains a g:select tag. I'm able to use other grails tags along with my own tags. I am using grails 2.4.4 (also tried 2.4.5) and version 0.1.10 of the plugin. Looks like it may be an issue with the mail plugin that's doing the rendering.

Here is the error I see:

Cannot invoke method getBean() on null object. Stacktrace follows:

Here's the line (913) from the grails 2.4.4 FormTagLib that I suspect the mail plugin is having issues with:

def messageSource = grailsAttributes.getApplicationContext().getBean("messageSource")

Thoughts on a work around?

Header doesn't work on Windows

I'm trying to generate pdfs with a header using the following code.

 def pdf = wkhtmltoxService.makePdf(
                view: "something",
                header: "/pdf/header",
                model: [
                         ...
                ],
                pageSize:"letter")

I get the following error on windows:

2015-08-12 10:28:40,318 [Thread-17] ERROR wkhtmltox.WkhtmltoxExecutor  - Error: Failed loading page http://file//C:\Users\****\AppData\Local\Temp\wkhtmltopdf6840842934454361668.html (sometimes it will work just to ignore this error with --load-error-handling ignore)

It seems to be related to wkhtmltopdf/wkhtmltopdf#1645. If wkhtmltopdf doesn't recognize the URL it will assume http... So, would it be possible not to specify "file://" prefix on windows?

IllegalArgumentException: Could not locate mail body

I am getting some exceptions (java.lang.IllegalArgumentException) which I am not able to figure out. So basically I was following the steps mentioned in your documentation and when I call the action, I get the following exception (below ********)

The wkhtmltopdf has been installed and it is working when using from commandline.

  1. showDetails is a partial template

Add options for viewport?

Viewport option is pretty essential for rendering pages correctly. Can we have this added in the wrapper? :) thanks!
