Thanks Scott - those are my feelings exactly.
I like the way the design worked previously, and changing it because a user might accidentally leave the comments enabled in
production seems silly. That is a user's QC problem, not a widget comment design problem.

Sorry I'm a bit lost, is the latest proposal something like this:
if (widget.properties.enableBoundaryComments == null) {
// widget.properties not set, only show where specified as true
if (context.enableBoundaryComments != null) return
context.enableBoundaryComments;
return false;
} else if (widget.properties.enableBoundaryComments) {
// widget.properties set to true, show everywhere unless specified as false
if (context.enableBoundaryComments != null) return
context.enableBoundaryComments;
return true;
} else {
// widget.properties set to false, show nowhere
return false;
}
As opposed to what was originally implemented:
if (context.enableBoundaryComments != null) return
context.enableBoundaryComments;
if (web.xml.enableBoundaryComments != null) return
web.xml.enableBoundaryComments;
if (widget.properties.enableBoundaryComments != null) return
widget.properties.enableBoundaryComments
return false;
I still prefer the original solution, in my experience the 99% use case for
this setting is:
- widget.properties.enableBoundaryComments=Y for development (ideally comes
this way OOTB)
- developer uses web.xml or context to set to N for apps/screens where they NEVER want the comments to show up (maybe some CSV
screen or something)
- widget.properties.enableBoundaryComments=N for production
I just can't imagine a reason why widget.properties would be set to N and a developer would decide to turn it on via the web.xml
or context and subsequently cause it to be shown in production (i.e. the reverse of the use case I've described above). It seems
like we're complicating an issue that is very unlikely to arise and only did arise because the example app's web.xml was set to Y
when it shouldn't have been (which confused Hans and caused him to make sweeping changes instead of just commenting out the
web.xml setting).
I really don't think there is a perfect solution but I'd rather advocate a
simple one that can easily be remembered.

Yes, there is some value in being able to have boundary comments always on… so Adrian are you coming around to agree with the
approach Hans introduced?
Why don't we use the widget.properties setting if there is one, otherwise look at the parameters Map (i.e. request parameters
and web.xml context params). By default, i.e. in SVN, the value will NOT be set.

Having them on by default during development is very helpful - I use them all the time. I can view the page source of any
screen to see where the widget XML file is located that generated the screen. It seems to me with the method you proposed, I
will not be able to do that - because comments will be off. I would have to hack the URL and add a parameter to see them, or I
would have to modify the application's web.xml file and restart the server.

Based on this I'm actually reconsidering my position, however the current
implementation is still not adequate.
It sounds like the goal for the widget.properties is to make it easy to go into production and make sure that no boundary
comments/etc are added anywhere in the system. To do that effectively you need a single setting for the whole system, and that
setting should override everything else (i.e. not even allow for a parameter to be manually added which may expose
implementation details that you want to keep hidden).
For that purpose a property would make sense, but the logic has to be carefully done (not the shallow logic that has been
discussed so far). It would need to be something like: if (widgetVerbose property == false) then don't show else if
(widgetVerbose parameter (using default OFBiz parameters Map, takes into account both URL parameters and web.xml context
parameters) == true) then show else don't show.
In other words, if the widget.properties setting is false, then never show boundary comments. Otherwise, ignore it and use the
parameters value if true, and overall default to false.
Wow, is this really that hard?

As i wrote before i am fine with this if in the trunk the setting of
widget.properties is not overridden by default in web.xml for some
component what was the case originally.

David,
Keep in mind that the original design is one that you participated in.
The agreement on the setting precedence in the original Jira issue was this:
widget.properties -> web.xml -> URL parameters
where widget.properties is the global default, which can be overridden
by a setting in web.xml, which can be overridden by screen widgets or
scripts or whatever (via the current context Map).
The design worked great. Then Hans changed it due to a misunderstanding
of how the design works. Despite repeated explanations of how the design
works, and requests from three PMC members to revert his change, he
refused to change it and threatened the community with a commit war.
Since then we have had a number of issues reported on the mailing list
describing how his change makes the setting unusable.
It amazes me that a single -1 vote vetoes a change in the Apache
community, but three -1 votes from PMC members can't revert this obvious
break in software design.

No. The approach suggested by (and committed by) Hans is that the
setting in the widget.properties file overrides any other setting.

No one agrees with which approach? The approach that if you pass a
widgetVerbose=true HTTP parameter that it should override the
widget.properties setting? I agree with that approach…

widget.properties's widget.verbose setting has precedence over

ModelWidget.widgetBoundaryCommentsEnabled() written this way for
some reasons?
there was a lengthly discussion of this. As long as by default the
properties file is not overridden in web.xml is fine either way.
Another issue is that these HTML boundary comments get outputted
even though the view handler is set to "screencsv". In the
widget-screen.xsd, the only way to invoke a template to produce
CSV is using<html><html-template />, but this always adds HTML
comments even if the output is CSV (see HtmlWidget class). Maybe
we could introduce a<csv> element or something like that?
Anyway, both of those problems combined mean that there are no
apparent clean ways to remove the HTML "template begin/end"
boundary comments from the CSV output if you try to draw it with
an *.ftl template. A workaround kludge for now is to invoke
the FTL manually through a Groovy script.
Thanks
