Re: Weird IWS Bug (?)

Jon, and others,

When dealing with output arrays (e,g, an array being returned as a
response by the web service), the recommended step is to select "detect
length fields" and add a length field PRIOR to the output array. At one
time the length field was limited to integer data types, but that is no
longer the case (depending on how current you are with PTFs).

So in the following example, things look correct:

dcl-pi RestSrv4 ExtPgm;
requestedCat Like(catcod);
result char(20);
productList_LENGTH packed(5);
productList LikeDS(product) Dim(20);
end-pi;

I am assuming that productList_LENGTH and productList are output
parameters,

So, in the RPG code, I would expect productList_LENGTH to be initialized
to zero. Then there would be some sort of loop where the productList
array is filled. And if you filled the array with 5 elements, then you
need to set the productList_LENGTH field to 5. That is it,

That is what I thought I was achieving _by_ selecting the Detect
Length option Anshul. Guess I had it back to front.

It just tried redeploying and deselected the detect length but no
other options appear and PRODUCTLIST_LENGTH still appears in the output.

Can you tell me what the name of the box I'm looking for is and on
what screen it appears.
