Re: JSConfirmPanel vs file download?

[Michael Sharp via Webobjects-dev]

Hi,

Use ERXJSConfirmPanel.

JSConfirmPanel uses a broken invokeAction implementation.

Re: is there a trick to know that a property of EO did change?

[Michael Sharp via Webobjects-dev]

ERXGenericRecord.changesFromCommittedSnapshot

if (changesFromCommittedSnapshot().containsKey(MY_KEY)) {
  propertyDidChange(MY_KEY);
}

As mentioned by Aaron this could be wedged into overridden setters, 
validate methods or even worked into your eogen template if you 
wanted this behaviour model wide.

It might also be worth looking at the audit trail implementation in 
ERCoreBusinessLogic for ideas on a configurable observer/notifier.

Sharpy.

Maven builds and Generate Bundles

[Michael Sharp]

Hi All,

As I continue my Maven journey I now find myself with a workspace consisting of 
both Maven and Ant WO projects. All my legacy builds are bundle-less while my 
Maven projects require the Generate Bundles WOLips preference checked. I see 
the same behaviour in both new and migrated Maven projects.

Is it possible to run Maven WO apps without Generate Bundles checked? Ideally 
I’d like to leave my debug/run launch configs for my legacy applications 
unchanged.

Thanks

Sharpy.

Hi Samuel,

I’m happy to create a pull request but I’m not sure there’s an appropriate 
destination branch at wocommunity/wolips yet.

I’d like to see jenkins.wocommunity building this too. I have jenkins building 
it here with both rebel and jprofiler support, although I’m unable to test 
those particular features.

Re: Code completion for a component's binding

[Michael Sharp]

I've wondered myself, so I just had a sniff around some API files.

e.g. ERXEditDateJavascript.api contains the following:
binding name=dateformat defaults=Date Format Strings/

 … and offers the right hand side completion of exactly that in the wod editor 
- date format strings.  Changing this to:

binding name=dateformat defaults=Numbers Format Strings/

has the expected effect - number format completion choices.

I guess these come from somewhere in WOLips, not sure if they're configurable. 
Will keep digging.

Re: Code completion for a component's binding

[Michael Sharp]

They seem to be defined in code in WOLips. The possible values for defaults 
here:

org.objectstyle.wolips.bindings.api.IApiBinding

public static final String[] ALL_DEFAULTS = new String[] { Undefined, 
IApiBinding.ACTIONS_DEFAULT, Boolean, YES/NO, Date Format Strings, 
Number Format Strings, MIME Types, Direct Actions, Direct Action 
Classes, Page Names, Frameworks, Resources };

And dealt with here org.objectstyle.wolips.bindings.api.ApiUtils

eg

if (Date Format Strings.equals(defaultsName)) {
  validValues.add(\%m/%d/%y\);
  validValues.add(\%B %d, %Y\);
  validValues.add(\%b %d, %Y\);
  validValues.add(\%A, %B %d, %Y\);

 I've wondered myself, so I just had a sniff around some API files.
 
 e.g. ERXEditDateJavascript.api contains the following:
   binding name=dateformat defaults=Date Format Strings/
 
  … and offers the right hand side completion of exactly that in the wod 
 editor - date format strings.  Changing this to:
 
   binding name=dateformat defaults=Numbers Format Strings/
 
 has the expected effect - number format completion choices.
 
 I guess these come from somewhere in WOLips, not sure if they're 
 configurable. Will keep digging.

Re: Creating an AjaxModalDialog wizard

 What is the correct way to create a wizard using AjaxModalDialog? I have a 
 page that pops up a dialog using AMD. Inside this dialog, I would like to 
 transition between pages, for example next/previous page. I've tried using 
 AjaxSubmitButtons and using the action binding but that did not work. I'm 
 thinking I could have an AjaxUpdateContainer around the contents of the 
 entire dialog component and then do a SwitchComponent upon refreshing but 
 that seems quite clunky. I was thinking that the component returned from the 
 action binding would replace the current contents.

AMD is an updatable container itself, without wrapping its contents in an AUC.

AjaxModalDialog.update(WOContext, String)

So setting some state in the action methods bound to AjaxSubmitButtons and 
calling update would allow you to make some determination on what to render 
within the AMD.

As for whether there's something that makes in nicer in Wonder, I'm not sure. 
The answer is usually yes though!

 I saw a brief discussion on this between Chuck, Mike and Clark Mueller back

Re: Fluffy Bunny question

I use folders for nesting models  eogen files within the Resources directory. 

I have some frameworks with enough models to make expanding the Resources

 I have an app and a separate WO framework. All my EO model files are in the

 In Eclipse, when I run the app, everything is fine. 
 
 When I make a Resources/model folder in the framework and then move the EO

 EO model files cannot be found. 
 
 Ok, so this is not-so-fluffy bunny but what if I really want to put

 make this happen? Is it in WOlips itself or some XML file? 
 
 Many thanks for any tips or pointers,

Re: Problem wo loop WOHyperlink

[Michael Sharp]

Hi Hugo,

You could use a Component Action rather than a Direct Action in your 
WOHyperlink.

.wod

DeleteLink : WOHyperlink {
action = deleteRecord;
}

The deleteRecord() method in your component class would need to:

* call delete on your entryItem enterprise object
* call saveChanges on your editingContext
* return a WOComponent or WOActionResults implementation, eg context().page()

Getting your git chops on

[Michael Sharp]

After reading the Most Requested thread I thought I'd relay my experiences, 
not about WOnder but about SCM in general. This all occurred within a team 
environment but I'll refrain from using the term we as it's more about my 
perspective.

For my projects, I used svn. Not really used, just sort of got by with it.

I was cycling through the 2 svn/eclipse integration tools that I was aware of 
when one pissed me off more than the other, or with every eclipse upgrade.

I was rarely using any svn features beyond commit/update after being repeatedly 
touched by getting into all sorts of trouble with branching and merging.

I was profane x100 anytime I had to do any sort of moving, deleting or 
refactoring with folders/directories.

It was a sheltered and sad SCM existence, but I was a bit daunted and 
overwhelmed with the git thing. I was putting up with the devil I knew..

We moved to git. The birds chirped and the sun shone! Well not quite, but the I 
think the key message is that we were using git. Mileage is invaluable.

I had no choice but to manage my local and remote repos. I employed a 
standalone tool, SourceTree (maybe if I did this for svn I would have advanced 
with it too).  Along with egit and cli I had an arsenal to work out any issues.

I made mistakes and still do, but I don't find myself painted into a corner 
like a was so many times fighting with Subversion or Subclipse.

For a project like WOnder I'd look at maintaining a private remote repo 
(bitbucket's good with unlimited private repos, or if you're so inclined, pay 
for github) to start with. Maintain the changes from the upstream master, make 
the mistakes munging/rebasing/merging/breaking your changes in with the 
upstream.  Making these sort of messes on a public GitHub repo was/is 
definitely off putting for me..

For my projects I now I find myself creating feature branches for the most 
trivial of changes, because I can, confidently. I'm rebasing this, stashing 
that, pushing etc etc and generally using an SCM system as it was intended - I 
think :-/

Summary: if you want to use git, you have to use git..

Sharpy..

Re: WORepetition validation error

WOLips binding validation seems to be a temperamental and mysterious beast.

Last week for me it was WOImage with validation telling me I must have a 
filename value when framework was also bound, which of course was already the 
case.  So that gave me errors in all my projects!

A combination of closing/opening projects, relaunching eclipse, refreshing, 
cleaning, standing on one leg and finally apathy eventually saw validation 
doing the right thing again.

It's frustrating but I'm learning to live with it.

Re: update a WOComponentContent from my code?

[Michael Sharp]

Hi Ted,

I'm not sure that what you're describing as happening is actually the case.

AjaxUtils.redirectTo isn't updating an area of your page surrounded by an 
AjaxUpdateContainer, it's redirecting your browser to a full page component.

It sounds like you're interested in updating parts of your already rendered 
page using Ajax, yes?

You can call AjaxUpdateContainer.updateContainerWithID in code, or use the 
updateContainerID binding on AjaxObserveField to nominate the AUC to be updated 
after the observed field(s) submit their contents.

Re: ajaxtabbedpanel ??

[Michael Sharp]

I think you're going to have to have a form per tab.

With a form wrapping the entire ATP, when tabs are selected form values are 
sent for the rendered form fields  only and not the hidden/not in the DOM 
fields.  The app seems to interpret this as nulls being provided for the 
missing fields, or in this case a default value of false.

If you override validateTakeValueForKeyPath you should see keypaths for non 
rendered fields showing up with null/false values when you select tabs..

Re: ajaxtabbedpanel ??

[Michael Sharp]

I do use TabbedPanel in an AMD so I'll try.

Any errors in eclipse console or javascript errors in the browser?

Is it a problem with Tab2 or with any tab after the initial tab is displayed. 
If you give Tab2 the binding of isSelected = true; does it display the 
correct behaviour?

 the tabpanel is on an AjaxModalDialog, when I create the modal dialog, I pass 
 in a user object. user has a to one relationship with securitySettings.

So when you say pass in an object, you mean supplied as a binding to the 
component where the AMD is declared?

I can't reproduce the problem, maybe the contents of your .wod for TabbedPanel, 
Tab1  Tab2 might help..

Sharpy..

 
 on panel one, I am displaying and editing user metadata. on panel two, I want 
 to edit some security settings.
 
 if i put on tab one:
 see user area wo:WOCheckBox checked = 
 $theUser.securitySettings.seesUserManagement /
 
 I get the checkbox with this user seesUserManagement setting.
 
 However, if this same code is on tab two, there is no connection to the 
 object.
 
 
 wo:WOForm multipleSubmit = true;
  div class = tabBox
webObject name = TabbedPanel
  webObject name = Tab1
table class = tableDefs width = 550
  tr class = meta1
td width = 110First Name/td
tdwo:WOTextField value = $theUser.firstName size = 65 
 //td
  /tr
 
/table
 br/br/
 
 see user area wo:WOCheckBox checked = 
 $theUser.securitySettings.seesUserManagement /
 
 /webObject  name = Tab1
 
 webObject name = Tab2
 
 wo:WOCheckBox checked = $theUser.securitySettings.seesUserManagement /
 
 /webObject name = Tab2
 /webObject name = TabbedPanel
 /div  
 wo:AjaxSubmitButton action = $cancelEdits value = Cancel 
 /wo:AjaxSubmitButton action = $save value = Save /
 /wo:WOForm
 
 
 why doesn't tab2 connect to $theUser.securitySettings.seesUserManagement 
 
 on tab1 the checkbox is checked (correct) however on tab2 no check.
 
 I don't even know if I am explaining this clearly enough.
 
 Help, please.

Re: EOModel and derived column.

[Michael Sharp]

Yep, still need to override the derived attribute's getter and mimic/duplicate 
the concatenation (in this case) to ensure it reflects the uncommitted changes, 
very noticeable when you have a new object that hasn't been saved to the 
backing store!

The big gains from this type of attribute become apparent when building 
qualifiers..

Re: Expand and collapse a row

[Michael Sharp]

Tables and individual rows are always tricky as the AUC's div can't be in 
rendering no mans land, ie outside tr tags but inside the table.

If you need to hide/show rows that preserve column structure of the enclosing 
table you might need to have the entire table in an AUC and determine which 
rows are rendered with WOConditional.

Re: ERPPieChart pie piece color

[Michael Sharp]

The colours come from JFreeChart's DefaultDrawingSupplier.

There's nothing you can supply in the objects that go into the items array that 
will affect rendering. The items, nameKey and valueKey bindings are all about 
building the dataset for your chart.

If you really wanted to go down the path of having ERPlot build the chart for 
you with the colours of your choice you'll probably need your own 
DrawingSupplier implementation which would allow you provide an array of 
colours for rendering, then use the configurations binding the set your 
DrawingSupplier for some keypath similar to plot.drawingSupplier.

I think you should take the responsibility away from ERPlot for building the 
chart. If you build it yourself you gain control over changing the rendering 
values for individual sections/items etc, something you can't achieve with the 
configurations binding and kvc..

Sharpy..

Re: Full URL on dev

Hi James,

I'm able to build complete URLs in both dev (directconnect  webserverconnect) 
and deployment environments using the request header value for one of the keys 
like server_name or host, or on an ERXRequest using the remoteHostName() 
method. This gives me the appropriate host:port value and the rest can be 
gleaned from the uri() method on WORequest.

That's what works in my setup anyway, a dig around your request headers would 
be a good start..

Re: from JFreeChart (BufferedImage_) to NSData_

JFreeChart lineChart = createChart( dataSet );
ByteArrayOutputStream stream = new ByteArrayOutputStream();
ChartUtilities.writeChartAsPNG(stream, lineChart, 500, 300);

Alternatively you can use writeChartAsJPEG.

Or let ERPlot deal with it by using the chart binding:

MyChart : ERPCategoryChart {
chart = lineChart;
width = 500;
height = 300;
}

 I put a new Example project in Wonder. It is Examples/Misc/ERComponentTour. 
 There is, after all, nothing analogous to the D2WComponentTour example and 
 there are lots of non-D2W components in Wonder. The first (and presently

 no ERPPieChart yet. And the examples there are probably not the smartest. It 
 certainly seems that for the AreaChart and WaterfallChart, this dataset does 
 not make sense. But this is the first version, so it is obviously better 
 than what was there before. And anyone who wants to show better examples of 
 these components is certainly welcome to do so.
 
 This example does show a minimal usage of the ERPCategoryChart. Let me know 
 if this helps at all. Or, if it does not, what would be needed to make it 
 make more sense? Let me know what you end up figuring out and I can probably 
 use that to improve the example.

Re: JFreeChart/Wonder liftoff

[Michael Sharp]

Hi Baiss,

All you should have to do is just add a ERPPieChart component to your 
WOComponent, eg

MyChart : ERPPieChart {
name = Monthly Totals;
items = myArray;
nameKey = name;
valueKey = amount;
chartType = PieChart;
}


You can gain a fair bit of flexibility with the configuration binding, and 
also you can use the chart binding on it's own if you already have a 
JFreeChart and just want a nice way to include it in your component.

Cheers,

Sharpy

Re: valueForBinding and indirectly referenced types

[Michael Sharp]

OK it was just the act of casting Object (from valueForBinding) to my  
subclass which required access to my class hierarchy and non-exported  
jars.  It's all trivial anyway as everything's exported as it should  
be..

I'm curious as to why I don't get any build or runtime errors with  
synchronising components when these jars aren't exported, but once  
valueForBinding is introduced to the component it explodes. Is it  
possible there was always a potential for runtime issues but I  
hadn't come across it yet?

valueForBinding and indirectly referenced types

[Michael Sharp]

I'm trying to change an existing component to be non-synchronising.

The component imports classes from my framework that extend classes  
from jar files that are included in my frameworks class path.  My  
component only accesses methods from these subclasses.


When I cast the result of valueForBinding to one of these types  
eclipse gives me a build error about the build path not being complete  
-   The type 'some.class.from.jar' cannot be resolved. It is  
indirectly referenced from required .class files
