Error "Imported page does not exist"

[liayn]

This error occurs using latest version from TER 2.0.1 when using sourceFile and importPage and when a PDF is created containing multiple pages. This issue is probably related to #41.

One problem is that there is broken code in
https://github.com/bithost-gmbh/pdfviewhelpers/blob/master/Classes/Model/BasePDF.php#L199

$this->tpl is never defined. A strict comparison against 0 is always true. This leads to calling $this->useTemplate(NULL);, subsequently causing the mentioned error.

@liayn thanks for reporting!
@maechler could you have a look?

@liayn Thanks for reporting! Maybe $this->tpl has been renamed to $this->templateId in FPDI v2. But it could also be that more things changed, I will test this as soon as possible.

I pushed a very dirty workaround, which fulfills at least our current needs

I actually think that it is a good fix for that issue. I had a closer look at FPDI, there is no way to determine the most recently used template anymore, thus we have to keep that information in our own class.

However I changed the implementation to not rely on an additional method, because I think this is less error-prone. I also added functional tests covering that issue.

pdfviewhelpers/Classes/Model/BasePDF.php

Lines 214 to 219 in e6d1b73

	public function useTemplate($template, $x = 0, $y = 0, $width = null, $height = null, $adjustPageSize = false)
	{
	$this->currentTemplate = $template;
	parent::useTemplate($template, $x, $y, $width, $height, $adjustPageSize);
	}

Thanks again for your contribution! If you like the project, please consider giving it a star :)
I just created a new release v2.0.2 that includes your fix.
