Empressa 5 MvFILTER functions

[sebenza]

Can MvFILTER still evaluate functions in the filter attribute in 5.00+?

For example:

MvASSIGN NAME="l.expr" VALUE="{'func(l.retval, ' $ l.expression $ ')'}"
MvFILTER NAME="DB" FILTER_TYPE="variable" FILTER="l.expr"

A partial answer, Scott, particularly in response to the word "still". No changes in the engine between 4.x and 5.x ought to have changed the way the MvFILTER tag behaves. If the function calls worked under 4.x then they should continue to work under 5.x.

Hopefully, that answer narrows down the possible sources of the problem you are troubleshooting.

Hi Mark-
I just tested the same script on Empressa 4.14 and it returned the correct result. Nothing was returned on 5.03. With that said, something must have changed. Is this a bug?

[Mark Hughes]

It sounds like a bug, albeit an unexpected one.

Can you work around it successfully by evaluating the expression, assigning the result to a variable and using the variable in the FILTER attribute?

Nope, because the expression is being passed from another function.

OK... I found a work around for this. The function being called appears to have to be in the script before the line calling it.
