3718.0. "Problem displaying constructed type on the map" by SWORD1::SHIAU () Thu Sep 10 1992 15:11

I am having problem with Iconic Map running a function module we are about to
finish. Although it's not a requirement to close this phase, we would like our
tool be able to kick off and display the output from Iconic Map. The tool is 
Path Tracing Tool which pulls a lot of information for each node or node4 on 
the paths between 2 given nodes. When we run it from the IM, we know the trace 
is doing the thing but it has problem displaying the output. We get this error 
message: "attempt was made to push into a Constructed type. The type encountered 
is not a CT". We have no problem at all from FCL. It gives this message when 
there is any output including exception messages we put out. Is there anything 
we need to do in order to fit into this constructed type?

The only special thing we did in the MSL is that we use a lot of RECORD or 
sequence of RECORDs to differentiate each level of the output (forward/backward
path, paths, node infor, circuit infor etc.) to make it more readable and also 
because we couldn't get SET and SEQUENCE to work. The fields of the record are
not necessary filled up depending on the request and whether we can get the 
information from AMs or not.

Any help will be appreciated. If more information is needed, please let me know.

	Jerry, For V1.2, each field of a record must be filled in. The Iconic Map cannot accept a record with some of the fields filled in and some of the fields not filled in. If you are trying to output sparsely filled records, that might be your problem. Verna

	Verna, Thank you for the answer. But why FCL is able to handle our output and IM is not? And more important question: when SET, SET OF, SEQUENCE and SEQUENCE OF and any combination of them will work properly? Best regards, Gene.

	Gene, The FCL and the Iconic Map do not use the same algorithms for all datatype validation. In general, the Iconic Map does more checking. We are hoping to include sparse records as part of V1.3. I am scoping the task right now. Verna
3718.4	sparse records have been implemented	TOOK::FLETCHER		`Fri Oct 09 1992 10:36`	5
	Empty and sparse record handling in the IMPM have been put in. Try using x1.3.2 kit.
