Warning on Unsaved Changes Functional Pattern

Overview
One advantage of integrated applications is users can easily navigate just about anywhere based on current needs. However, with the added flexibility also comes the increased risk of unsaved data accidentally being lost when navigating away from a page. Therefore, many applications typically warn the user when this is about to occur. Using the new warning on unsaved changes feature, 11g ADF applications can easily implement this type of functionality.

Hi,
I have a page with an edit form. The user can close/leave the page by clicking on different buttons (menu items, close icon, back button). In this case, the system should warn the user about unsaved data. Furthemore, I want to skip data validation. I tried to implement the "Warning on Unsaved Changes Functional UI Pattern", although this approach doesn't skip data validation. How should I do this?
I'm using ADF 11g.

Hi,
I am not familiar with the document, but options I see are
option 1: set uncommitted data warning property on the af:document to "on" (I am not sure, but think this is already available in JDeveloper 11g R1)
option 2: use the controller context (ControllerContext) of the ADFc task flow handler to detect if the transaction is dirty
option 3: use a managed bean that accesses the AM in the DataControl to check if the transaction is dirty
FrankThank you for the reply Frank. Below are my response to your options
response to option1:
I have already set the uncommitted data warning property on the af:document to "on" (yes, the option is already available in JDeveloper 11g R1) and even set the bounded task-flow inside the region of my page as "critical", but when I navigate to other pages thru the navigation items in my template header, the prompt for uncommited changes did not show.
response to option2:
Which class of my project will use the controller context to detect if the transaction is dirty? I have tried to google the uncommittedDataWarning property which lead me to the DirtyPageHandler class. I have read on DirtyPageHandler class API that in case I do not set an implementation the default implementation will be used- and if I me quote from the API -"that default implementation will always return false from isDataDirty and will do nothing in response to a trackNavigation call." I wonder if aren't there any concrete samples to make this work? As I understand, the uncommitted data warnings is one of the publicized new features of JDeveloper 11gR1. Nevertheless, I have tried to follow allong and did create my own implementation:
1.) I did override the isdataDirty method to always return true,
2.) override the trackNavigation method to "System.out.println("prompt");",
3.) and created a file named oracle.adf.view.rich.context.DirtyPageHandler in the META-INF/system folder of my project, and
4) created a one line text which represents my implementing class in the created file in #3.
but still nothing especial happened.
response to option3:
What exactly is "AM" in the DataControl?
Your feedback on this is very much appreciated.
Thanks,

Missing Article: Warning of Unsaved Data Functional Pattern

Hi
I bookmarked an article a while back which showed a functional pattern for warning of unsaved data when navigating away from a page.
However, now that I need to investigate and impliment this the link is broken.
Does anybody have the new link, link to a similar article / blog?
Thanks,
Mario

Hi,
if you are on a recent version of JDeveloper 11g then this functionality is provided out of the box. Also have a look at the af:document tag on your pages. It has a property "uncommittedDataWarning" you can set to on or off so this functionality is present event for single pages

Pop up Warning on Unsaved Changes

I have an ADF JSFF page.
It contains a drop down menu through which I could see details of a particular event b ased on the option selected in the dropdpwn choice.

                </af:selectOneChoice>
The moment I select one of these choices and try to navigate to another page I get a popup that says "This page contains uncommitted data. Would you like to perform navigation. Press OK to continue , or cancel to abort navigation"
How do I remove this popup ??
Thanks in advance

User, how should we know?
You did not give and information about the app, what's done before you try to navigate away, no jdev version.
You can turn the warning off completely, but i suggest you think about it first. If you get the warning, the transaction you are in is dirty. You loos every change you made if you navigate away from the page. Check Jdeveloper,Oracle ADF &amp; Java: Uncommitted/Unsaved Data Warning on page Navigation-Oracle ADF for info where to configure this.

Warn by leaving a form view with unsaved changes

Hello JSF / Richfaces users,
maybe that's not the first time, that someone asks this question here, but unfortunately I couldn't found any concrete examples on the forum. So I'd like really to get your help:
I'd like to put some "input listeners" on my form views, so that when the user makes changes (typing in inputText, selection another value in selectMenu or checking a Checkbox), then he clicks on another Button / Link without saving, he shoudl will be warned by a dialog box remebering him to save the changes or leaving the view without saving (changes will be lost).
I tried at first to put a boolean "inputChanged" on my Bean, then setting it to true with an adapted event (onchange) by each component. And by the buttons/links which link to another page I tried to show a <rich:modalpanel> once the value of "inputChanged" is true but I couldn't realize this conditions.
Thereafter I found a solution based on Javascript:
<script language="javascript" type="text/javascript">
    // Keep flag when something had changed
    var changed = false;
    Save in "changed" flag, whether an input had been done by the user.
    after that the calling of this method will be removed
    from the corresponding attribute of the input elements,
    in order to avoid redundant method calls */
    function storeChange(aChanged, aElement) {
        changed = aChanged;
        aElement.setAttribute('onchange', '');
    Finally and when the "changed" flag is true, a confirmation message will be shown
    to confirm whether the page could be left.
    window.onbeforeunload=function unloadAlert() {
        if(changed) {
            return 'You have unsaved changes on the page. If you click on OK, the changes will be lost';
        return null;
</script>{code}
And in the view:
{code}<a4j:form>
        <h:outputLabel id="label_name" value="Name" for="in_name" />
        <h:inputText id="in_name" value="#{bean.name}"
            onchange="storeChange(true, this)" />
        <br />
        <h:outputLabel id="label_email" value="E-Mail" for="in_email" />
        <h:inputText id="in_email" value="#{bean.email}"
            onchange="storeChange(true, this)" />
        <br />
        <a4j:commandButton oncomplete="javascript:changed=false"
            value="Save" />
    </a4j:form>{code}
And now I'd
like rather than the JS terriying dialog box, a user-friendly rich:modalPanel which should do the same function.
For any
indication I will be very very thankful

Hi David,
Thank for the prompt answer. I've tried that before but I have put that in checkin action. So that didn't work before but now as per your suggestion it works nicely. The form isn't evaluated.
However, this time my changes aren't reflected on the user.. Basically what I do is
- checkout user view (with empty form) (in an activity)
- update user view (in another activity)
- check in user view (in another activity)
however, changes are discarded. I used winmerge to compare and saw exactly the necessary fields are updated after update activity. but after checkin no changes are reflected. so what should I do now :(
Relevant actions are:
<Action id='0' application='com.waveset.session.WorkflowServices'>
          <Argument name='op' value='checkoutView'/>
          <Argument name='viewId'>
            <concat>
              <s>User:</s>
              <ref>accountId</ref>
            </concat>
          </Argument>
          <Argument name='type' value='User'/>
          <Argument name='id' value='$(accountId)'/>
          <Argument name='Form' value='Empty Form' />
          <Return from='view' to='user'/>
          <Return from='WF_ACTION_ERROR' to='error'/>
        </Action>
        <Action id='0' application='com.waveset.session.WorkflowServices'>
          <Argument name='op' value='checkinView'/>
          <Argument name='view' value='$(user)'/>
          <Return from='WF_ACTION_ERROR' to='error'/>
        </Action>

APEX 4.1 is it possible to remove pagination "unsaved changes" message?

Hi,
We've developed a tabular form in APEX 4.1 which only contains one updateable column. Once the user modifies the column it raises a Dynamic Action which UPDATES data at source table. The problem is after modifying any field and clicking on pagination link, we get the following alert message "This form contains unsaved changes. Press "Ok" to proceed without saving your changes."
Is it possible to get rid of that message? I found the way to translate the message but nothing to remove it. We also saw pagination is calling a JavaScript function called paginate, would it be possible to modify its definition to disable the message somehow?
Thanks

Hi,
Apex uses a global array called gTabFormData to store the original form values when the page loads and identify which ones have been modified when the user does pagination. So, a hack you could use is to call this function right after you saved the changes to the database:
function resetFormCachedData() {
    var c = $x_FormItems($x('report_<REPORT_STATIC_ID'>)); // e.g. report_MYSTATICID
    for (var e = 0; e < c.length; e++) {
        if (c[e].name != "X01") {
            gTabFormData[e] = c[e].value
        } else {
            gTabFormData[e] = "0"
}I suggest putting this code in a JS library, so if Apex changes in a future release (e.g. providing a documented way to do this), it is easy to change it too.

VIs that are never called or changed but always have "unsaved" changes

I have a large project. Whenever I close it, I always get a pop-up telling me that the same 7 sub-VIs have unsaved changes. I have not edited or changed these VIs in over a year. They are called by sections of the program that are conditionally disabled at the moment! I get this pop-up warning even when the last thing I did before closing the project was save every VI that is open.
The only clue I have to offer is that these 7 VIs are the only ones in the project that directly talk (via ethernet) to a motion controller. Is internet activity on my computer while I am working on the project causing these VIs to think that they have been modified??
-Geoff N.

Well, did you ever try to save those at the dialog? Maybe they are still in an older version?
If you open one of these VIs and look at the "lilst unsaved changes" of the VI properties, what does it say?

OWA_PATTERN regular expressions CHANGE function

Hello,
I'm trying to use the CHANGE function to match an expression and then change the matched part of the string. The twist is that I would like to pass the matched part of the string through a function before it is replaced in the original string. Here is an example:
Pattern: 'C'
Text: 'CAAACAAAC'
Resulting text: 'DAAADAAAD'
Where the 'D' is the result of calling a function. The actual call to the OWA_PATTERN.CHANGE looks something like this:
OWA_PATTERN.CHANGE(mytext,'C',myfunction(&))
where the & argument to myfunction is as specified in the ORACLE docs as a reference to what was matched. The line of code doesn't work however. Anyone ever done anything like this?

Unsave Changes

hi all,
sorry for asking again. there is one af:readonly table on my page, which i dragged from 'Data Controls'.on this table , i ve a 'Edit' button, which navigates to other page,
after selecting a single row.
On this page i dragged same collection fm 'Data Controls' as adf:form for editing purpose . i also dragged 'Commit' operation.its working fine.
But problem is that when i make a change in any field & navigates to page which contains table, without committing, that changes instantly reflected in table. i m navigating by a af:commandlink.
even i m refreshing that table's iterator 'always' in pagedef file,everytime i navigate to that page. it should read fm underlying model. but this is not happening.
i did for table in pagedef file- i created an 'action' inside 'bindings' node & created a 'invokeAction' inside executables, which is invoking 'action'.
<executables>
<invokeAction Binds="tableRefresh" id="tableRefreshonpageload" Refresh="always"
RefreshCondition="#{!adfFacesContext.postback}"/>
<iterator id="xxViewUp3Iterator" RangeSize="15" Binds="xxViewUp3" DataControl="AppModuleDataControl"
</executables>
<bindings>
<action IterBinding="xxViewUp3Iterator" id="tableRefresh"
DataControl="AppModuleDataControl" RequiresUpdateModel="true" Action="2"/>
</bindings>
plz help me, as i navigate to previous page any unsave changes should not reflect in table. i m using jdev10g.

FM8: File Always Opens Unsaved Changes

Hi,
I have a file in Framemaker 8 that always opens with "unsaved changes." I save the file, the asterisk clears, but the next time I open the file the asterisk is there.
I thought this might be a "missing font" issue and, as a test, turned off Remember missing fonts. This setting does not seem to impact this behavior.
Any help much appreciated.
Mary

I found a very nice explanation by Fred Ridder on Framers:
I think a better understanding of how cross-references are handled will help you under why I say this.
Whenever you open a file that contains one or more cross-references, FrameMaker refreshes each of those references. If the reference is to another location within the same file, the refresh is straightforward unless the cross-reference truly is unresolved due to a missing or hidden cross-reference marker. If the reference points to a location that is in another file that is already open, the process is similarly straightforward.
But if the reference points to a location that is in a file that is *not* already open, FrameMaker has to silently (without showing anything on your screen) peek inside the target file to retrieve the latest information for the refernce. If that file has any sort of problem that would throw a warning message during a non-silent open (e.g. an unavailable fonts message), FrameMaker is unable to peek inside it and therefore cannot find the marker it's looking for. It reports this failure to find the marker as an unresolved cross-reference. If you start by manually opening the file with the missing fonts issue, so that you can manually dismiss the warning message, then you will not get an unresolved cross-reference warnign when you open the original file because FrameMaker can now find the target marker when it updates the cross-references.
BTW, the updating of the cross-references is the reason why FrameMaker will warn you about unsaved changes when you attempt to close a file that you *know* you didn't make any edits in. Even if the cross-references did not actually change as a result of the update operation, the fact that they were refreshed counts as a change that FrameMaker thinks you ought to save.
-Fred Ridder
This makes sense and matches with what you said so succinctly Jeff. Thanks for the help.

Getting "ATTENTION: Unsaved Changes..." box via SCRIPT commands?

Hello,
When I exit DIAdem without saving all of my changes, a dialog box comes up:
"ATTENTION: Unsaved changes found in the following DIAdem panels:
"DIAdem - VIEW (File.TDV)
"DIAdem - REPORT (File.TDV)
"Do you want to save the changes in these DIAdem panels when leaving the program?
Is it possible to call this in a script? Or is there a better way to detect unsaved changes in any of the DIAdem panels?
Or...I will describe what I am doing and perhaps someone has a different idea to accomplish what I want? What I have done is set up some scripts so that users can open "DIAdem Project" files (TDM data with associated VIEW and REPORT layouts) and when users are opening a different "Project" I would like to give them the option of saving any changes they have made before loading something new.
Thank you!
Julia Moeller

Ok, I thought I would share what I wrote to get a box that looks exactly like what DIAdem brings up. One more question...is there any way to find out if my SCRIPT workspace has been changed? Then it would be perfect!
Thank you again, Julia

FDK Problem: "Unsaved changes in file" dialog with MIFs

Hi there
I have a problem saving MIF files using our FrameMaker API client.
After we have written out all our content, we're getting prompted to save unsaved changes in the .MIF file.
We're not sure whether to click yes here or not.
If we click yes, we then get a save dialog which prompts for a filename,
but has the default file extension set to .FM.
When you click "save", another message box appears telling me that I'm trying to save a
.MIF file in the .FM format and that is not allowed, and asks if I want to save it
as .MIF.
Although this is an a mere annoyance for me, it's probably very confusing for
customers who use our software, and I'm not sure whats causing it.
I've tried to address it by modifying the default save parameters within the FAPI
using this:
F_PropValsT saveParams = F_ApiGetSaveDefaultParams();
i = F_ApiGetPropIndex(&saveParams, FS_ModDateChanged);
saveParams.val[i].propVal.u.ival = FV_DoOK;
Needless to say, it didn't work. I'm wondering is thee another approach I should
be using?
Thanks
Eric

Hi Eric,
I'm not clear if your software is saving the file automatically, or whether the user needs to do it after your process runs. And, I'm not really clear on what exactly you want to happen after your code runs.
I do think that any open MIF file (even if in binary format, after being opened in FM) will cause that prompt when you attempt to close it manually, even if you have made no changes since the last save. My thought is that FM simply looks at the file extension and generates that behavior accordingly.
A few options you have (may be more, once I understand the situation better):
- Let the code close the file itself once it is done, using F_ApiClose(docId, FF_CLOSE_MODIFIED). This, of course, if the interactive user doesn't need to see it.
- Use F_ApiNotification() and F_ApiNotify to hijack the save request and save the file as MIF automatically, which should allow you to avoid the second prompt.
- Use notifications to hijack the document closure process itself, simply closing the doc upon request whether it has changes or not. Or, maybe you could add your own prompts. This would take consideration of whether you actually want to allow an interactive user to make changes after the code runs.
Just some ideas there. If you provide more info on what you want to happen after your code runs (presumably this is the translation thing), I might be able to help more.

Control authorization of mass change functionality via PCUI

Hi,
We are having the following issues with the Opportunity iview, com.sap.pct.crm.opp.opportunities_s.(Business package for CRM 5.0 and contains functionality CRMD_BUS2000111).
Once the user clicks Go..he has the list of Opportunities. He can select some or select all and use "Mass Change".
We would like to control the functionality of "Mass Change" attribute in the backend CRM System so that only a few people can be authorized to do this. However we are not able to find any CRM authorization
object that controls the mass change activity for opportunities and pursuits in the backend CRM System.
What is the backend CRM Authorization object that controls this functionality in the backend CRM System ?
Regards,
Rajan.K

Frank,
In IW38/IW3N we added our own Mass-Change button (in addition to the standard option) via Enhancement Spot ES_EAM_LIST_ENHANCEMENTS_EXT. This was required to perform functions that don't exist in the standard mass-change function e.g. mass-add/delete operations, mass-un-TECO, mass-un-CLSD, etc.
This Enhancement Spot may work for IE05 too.

Way to detect if an Indesign Document has unsaved changes

I have an InDesign document that I have saved. After saving the document, I make some changes to it. Now I want to detect if there are any unsaved changes in the document through JSX. I have tried to use the property document.saved, but this method only tells me if the document was saved for the first time.
If have some unsaved changes in a document that has been previously saved, document.saved still returns true.
Is there any other way to detect unsaved changes for a document?

@Kapoor – you could tell by the layoutWindow name. If a * is in front of the name, the document is not fully saved.
if(app.documents[0].layoutWindows[0].name.match(/^\*/)){$.writeln("doc not saved!")};
At least this is true for layout windows on Mac OSX.
In Windows the little * could be at the end of the name.
Can't remember. Currently I'm on OSX 10.7.5.
If it is indeed on the left right side of the name, you have to check on what OS the script is running and do the match accordingly.
