Hi,
nice catch! This could be even more interesting since 2.2 SQLTransformer
was also ported to C3 and might be affected by the same problem.
Please file an issue on JIRA, possibly referencing the original issue in
C2.1 (COCOON-1594), and the two mail threads you are referring to [1]
[2]. Then attach a patch with your fix: please remember to generate your
patch [3] against current SVN trunk [4].
Thanks!

Re: [BLOCKER] SQLTransformer bug 1594 - cause found
Francesco, thank you for your answer. This old thread is all I could find about problem with sql transformer. Later I've found another piece of information - now it's clearly about problem with cocoon 2.2 - and from 2009: http://www.junlu.com/list/59/462718.html I've compared source code for two classes - TextRecorder and SQLTransformer - from cocoon 2.1.11 and 2.2.0. 2.1.11 - There is function getAllText in TextRecorder, and SQLTransformer uses this function. 2.2.0 - there is no such function in TextRecorder. I use maven 2.2.1. Excerpt from my pom.xml: ... org.apache.cocoon cocoon-core 2.2.0 ... -- View this message in context: http://cocoon.10839.n7.nabble.com/BLOCKER-SQLTransformer-bug-1594-cause-found-tp28461p57547.html Sent from the Cocoon - Dev mailing list archive at Nabble.com.

I've read about trimming text in class TextRecorder (org.apache.cocoon.transformation.helpers) Was the class TextRecorder in cocoon 2.2 fixed too? Wow, that's an old thread from 2005! I don't think that fix for mentioned issue [1] was applied to 2.2 basically because I don't think that 2.2 existed at that time. However, I'd think that SQLTransformer in 2.2 did originate from latest in 2.1, so I wouldn't expect that this issue is still there.

Thanks for your reply, Carsten, I will do as you suggest. best regards Jeremy On 2 Nov 2005, at 18:38, Carsten Ziegeler wrote: Jeremy Quinn wrote: On 2 Nov 2005, at 18:11, Jeremy Quinn wrote: I can see two solutions to this bug : 1. remove the .trim() from the TextRecorder.getText() method, but I do not know if something else relies on this. 2.

I suppose another option would be to override o.a.c.transformation.AbstractSAXTransformer.endTextRecording in SQLTransformer, with a call to an alternative TextRecorder.getAllText () method. I'm getting old...I can't remember why the trim() was a "good think" :( I think, we should do a fix which has as little impact as possible, so I would vote for your last suggestion (getAllText()) for now. We can then have a look at the TextRecorder and it's use after the 2.1.8 release and perhaps provide a "better bug fix" if possible.
