[CWB] Indexing of metadata problem + no display of query results

[Hardie, Andrew]

Ah yes, that might well be the case. 

I can't remember about old versions, but the current text_id limit is 255.

Other ID codes have shorter limits imposed by the limitations of MySQL (which does not allow identifiers longer than 64 characters).

Another possible cause of trouble is non-allowed characters in the text id. It must be only ascii alphanumerics plus _ 

best

In addition to Andrew's answer: I often had the error complaining about
lines outside <text>. The not so obvious reason for that (after having
checked the xml structure in depth) were the text id's: of course, a
unique id per text is necessary. But you should know, that cqpweb allows
id's of a max length of I think about 25 characters and I sometimes had
longer ones. Cqpweb then just crops the id's and as a result you may
have non unique id's in your data... CQP does not complain about that,
but CQPweb...

Perhaps this is also the case in your data.
