Seting variables to an evaluated expression rather then a string?
This seems like such a simple topic, but I can't get it to work as
desired.
The need is to simply have a series of variables that are increments of
the first
A=100
B=A+1
C=B+1
Etc
This looks like a count, but the same value once set must be used
throughout the thread, so I want to set them as variables. The starting
point of A is a semi-random value.
I've got an expression that works now, but it seems way complicated for
the need. Is there a simplier way to do this?
Right now I have a User Parameter element setup like this
log1ID = ${__time(HMS)}
log2ID = ${intSum(${__V(${log1ID})},1,dummy)}
Can I define log2ID in some way to be a simple evaluated expression
rather then using the intSum function and needed that 'dummy' variable?
Thx
Steve

Agreed; the Edit menu does not work in fields.
It's only intended for use in the test plan tree.

Playing around more.. I see if I use control-c and control-v it works,
but using the Edit menu does not. Do you see that behavior? Jmeter
2.3.1 here

Works fine for me - but you may need to double-click to enable the
field for input.

Yes, typo on my part when trying to transcribe the screen since I can't
seem to copy/paste text fields from the applet in windows. I find
myself doing most text operations in the saved text files. Am I missing
something else there?
For instance, when trying to put large XML blocks into my samplers.. I
can't copy/paste into the sampler's body field. I open the test plan in
a text editor and manually insert it into the xml structure.

Thanks - that was kind of what I was looking for.

That won't work as the function is called __intSum, not intSum.

log2ID = ${__intSum(${log1ID},1,dummy)}
is a bit simpler and should work.

[It would be possible to make the variable parameter optional for the
special case of two integers as "intSum(number,variable)" does not
make much sense. Variable names can be composed of digits only, so
there's no way of knowing for the general case - unless one insists
that the variable name start with a non-digit.]
Use one of the script functions (Javascript, Jexl, BeanShell) to do
the calculation, e.g.
${__jexl(${log1ID}+1)}
but of course using script functions will necessarily increase the
overhead somewhat.
