Description From Bart van den Eijnden 2004-01-19 09:31:51

When building an invalid query, like "column" = and then nothing (no value), 
the map waits forever. 

This sounds like a bug.  When no value is supplied then the resulting filter 
expression should just be "column = ''".  This should be a valid filter that 
returns no results.  Can you please file this as a bug?

This is a mapserver bug, I'm reassigning this to Assefa.

Now when applying "attribute =  something" the map waits forever.  But when
applying "attribute = " the map is displayed right away.

example with world_testdata:  NA3DESC = Africa --> map waits

Verified on Fedora Core 1 Chameleon 20040625.

this is not an issue to stall beta 2 for.

works for me on winxp with mapserver 4.2.3 and chameleon cvs ... marking as
worksforme and Norm can re-open if this doesn't work when I package the beta 3.
