UWL Zip Configuration Upload "Unable to read file"

Question

Hi Folks,
System Info:
NW AS 7.02 JAVA Stack 702 Level 16
Background:
We're using the UWL for our Workflow based Approval Process in SAP FI-TV (Travel Management). For this we've been using the standard UWL configuration File com.sap.pct.erp.mss.tra (v.14 for WDA-Launchers) which is a zip containing the xml file and several property-files (for outsourced nationalized constants, as far as I understood). The Default action of most of the tasks is the opening of a WDA-Launcher which internally generates an ADS-based document containing facts about the trip which is then shown within that launched window/frame, i.e. a PDF.
Problem / Analysis:
We were recently contacted by angry endusers who complained about the fact that the window that is launched is not resizable and has no scrollbar which makes reading the form extremely tedious; and indeed, these properties are not set in the standard file. Assuming that Actions cannot be overridden/redefined like Views/Tasks with "high priority" etc. (is this the case? At least I haven't found a way) I have downloaded the standard zip archive, extracted the xml file, changed the window properties (added resizable=yes,scrollbars=yes), packed it back into a zip and uploaded, i.e. overwrote the original file. It then says the file has successfully been overwritten, after clearing the cache I can also see a new timestamp for the configuration, however the configuration has not really been updated, it's still the old one. Let me elaborate with some screenshots:
Untouched original File:
Changing the XML file:
Reuploading the File allegedly succeeds with a happy message with a green information icon and there's a new timestamp after clearing the cache. However, my changes are not there:
When I delete the original zip-file before uploading my changed one, I receive an error. I assume this error also silently occurs when I try to overwrite the existing standard file, but the system is a dirty little liar reporting a success.
I believe this is the exact same problem the OP of the following thread has/had Error While uploading the Config ZIP back but it seems it has never been resolved. I can't find anything usable on SapXSearch either.
Now, when I extract only the XML file from the archive and upload only that without all the property-files, then it works. However in that case, the UI looks terrible of course, because all the constants for labeling are missing, so that's not a feasible solution either.
I fail to understand what the problem is. Does the portal need some kind of special archive-type? Some kind of special compression level or anything? I tried zipping the new zip-file with winzip and 7zip. Neither works and I don't get what's the source of the problem.
Does anyone have an idea? Honor, glory and ponits shall be yours, if you do :-|
Cheers, Lukas

Answer 1

I am not sure what is causing the original problem, but I would image it has nothing to with the ZIP-format. When I upload UWL configuration files, I almost never even archive them - just upload the XML file as it is.
Also, I never touch the original/standard files. I just upload my own file with high priority (and the file includes only the things that I want to change/replace (or the new stuff)).
Also, could you do the needed change at the task level? Something like this:
<ItemType name="uwl.task.webflow.TS90000001.SAP_ECC_HumanResources" connector="WebFlowConnector" defaultView="DefaultView" defaultAction="launchWebDynPro" executionMode="pessimistic">
<ItemTypeCriteria systemId="SAP_ECC_HumanResources" externalType="TS90000001" connector="WebFlowConnector"/>
<Actions>
<Action name="launchWebDynPro" groupAction="" handler="SAPWebDynproABAPLauncher" referenceBundle="startWD" returnToDetailViewAllowed="yes" launchInNewWindow="yes" launchNewWindowFeatures="resizable=yes,scrollbars=yes,status=yes,toolbar=no,menubar=no,location=no,directories=no">
<Properties>
<Property name="WebDynproApplication" value="zleavereq_approve"/>
<Property name="WebDynproNamespace" value="sap"/>
<Property name="WebDynproConfiguration" value="ZLEAVEREQ_APPROVE"/>
<Property name="request_id" value="${item.Request_ID}"/>
<Property name="fpm_hide_close" value="X"/>
</Properties>
</Actions>
</ItemType>
