Usage of setTag('para','xpre') with report designer

Asked by Pieter J. Kersten (EduSense BV)

Hi,

I'm trying to allow preformatted text in reports. The documented feature is to switch parent container tags with setTag() from 'para' to 'xpre'. However, when I do that I get either a syntax error or an exception.

Tried:
[[ setTag('para','xpre') ]] [[ variable or removeParentNode('xpre') ]] syntax error (barks on brackets in expression - somehow convert.py considers this to be one expression)
[[ setTag('para','xpre') and variable or removeParentNode('xpre') ]] exception
[[ variable or removeParentNode('xpre') ]] [[ setTag('para','xpre') ]] exception
[[ (setTag('para','xpre')) and variable or removeParentNode('xpre') ]] exception

How can I process preformatted text in OpenERP (using 6.0, but 6.1 has similar issues)

Thanks in advance

Hi,

Try this [[ variable and setTag('para','xpre') ]] [[ variable ]]

Thanks,

Variation on a theme :-) See the results below.

     '' ]] [[ note or removeParentNode('para')
        ^
 SyntaxError: invalid syntax

This is in fact a parser error from convert.py
BTW, I couldn't find a single example using this feature. The few standard documents that use xpre are XSLT based.

Why not use <xpre> without the trick of using setTag ?

Hi Niels,

I would be happy to do that, if I knew how. Embedding <xpre> tags directly in sxw files simply print '<xpre>'. The same applies to all other possible tags btw.

Can you tell me how I can do this?

TIA.

It turned out to be a combination of a bug and a missing *advertised* feature: the rml_tag code returns an invalid string and the str2xml() code embedded deeply in rml2pdf/utils.py prevents tags from variables to be interpreted.

I've created a small patch for server 6.0, fixing both issues. Porting to other versions should be trivial. If anyone is interested, contact me.
