[CWB] CQPweb does not return results but blank page

[Hardie, Andrew]

Hi David,

Based on this error message, I believe the problem is that you have declared a tertiary annotation, but not specified a mapping table, in this corpus.

To test this, try doing a query in "CQP syntax" mode. If I'm correct, it will work fine.

Andrew.

PS. changing from weakly typed to strongly typed function parameters and return values was one of the big changes made in v 3.3.0 . I am reasonably certain the bugs from that changeover are pretty well shaken out.

Hi, Andrew,
Thanks for the help. I looked into the error log and it appears to be some variable type delcaration problem  to me as I compared the "query-lib.php" file with its  early 3.2.43 version and found you reengineered the code a bit and had all the variable type declaration  (e.g. string, bool) removed. Could this be the cause of problem? I pasted the error below for your reference:

It seems that there are no glitches at all from the beginning to the end until I started query after the installation of a preindexed corpus. There was no response but a blank page, showing no errors too. The preindexed corpus was taken from my server that was taken offline.  It was supposed to work well with  CQPweb.   I met the same problem when I tried the sample Dickens corpus.  I am using CWB 3.4.33 and CQPweb 3.3.10. My corpus was indexed with an earlier version of CWB (should this be an issue?).
