Hi,

The problem happen when I use Promatrix framework, but it is actually a common VFP view problem so I post it here in order to seek for extra and faster help.

I have a search view which always come up empty when it suppose to have 1 record!

The search view's SELECT command reads:
SELECT Stblcomp.compnam1, Stblcomp.compnam2, Stblcomp.compsnam, Stblcomp.compnick, Stblcomp.comprobn 
FROM ustb!stblcomp 
WHERE ( ( (  Stblcomp.compnam1 = ( ?GETcompnam1 ) AND  Stblcomp.compnam2 = ( ?GETcompnam2 ) ) 
AND  Stblcomp.compsnam = ( ?GETcompsnam)) AND  Stblcomp.compnick = ( ?GETcompnick ) ) 
AND  Stblcomp.comprobn = ( ?GETcomprobn )
Though it has 5 filter variables in it, the one that will be actually used in my test is Stblcomp.compnam1 = ( ?GETcompnam1 )
The view is opened with USE command in the framework:
	
	USE (slcViewName) ALIAS (slcAlias) &slcClauses 
	
	* The below IF structure below are inserted by me
	* V_RIDUP is the alias that I use to open the above search view
	IF slcAlias = [V_RIDUP]  
		SET STEP ON 	
		BROWSE
	ENDIF
When the SET STEP ON bring up the debugger:
In the debugger 's LOCAL window:
slcAlias is [V_RiDup]
slcClauses is ""
GETcompnam1 is "Highclass Computer Software "
GETcompnam2 is "%"
GETcompsnam is "%"
GETcompnick is "%"
GETcomprobn is "%"

In the debugger's WATCH window:
ALIAS() is [V_RIDUP]
EOF() is .T.
BOF() is .T.
SET("EXACT") is "OFF"
LEN(stblcomp.compnam1) is 40
LEN(GETcompnam1) is 40

The BROWSE after the SET STEP ON as shown above always come up empty... that is the view has no data in it.
However, If I browse directly the underlying table stblcomp which the above view is based on I can find a record whose compnam1 field is "Highclass Computer Software "

I really can't find where could be the error that cause the view to open up empty, it should contain 1 record
Anything else that I could have missed? or any tips on debugging this kind of error?

Btw,
if I try to change the filter Stblcomp.compnam1 = ( ?GETcompnam1 ) to Stblcomp.compnam1 LIKE ( ?GETcompnam1 ), the view come up with 1 record. But I can't use LIKE here because the search view is used to check for duplicated field values.
