Usually "null is not an object" manipulation?
Hi guys,.
I want to find and change some textlayers in my compositions, but it does not work when the layer is not there.
var layer = app.project.item (1).layer("layername").sourceText.value;
When NomCouche is found, all right, but when no layer with that name, came the errormessage "null is not an object" and stop the script.
I tried a try-catch and an if condition, but the error is still the same.
How can I generally avoid this message and can deal with this problem?
When no layer is not found, the script should message the user and make other functions while when the layer is found.
Cheers.
If the app.project.item object (1) .layer ("layername") does not exist or is not a text layer, you will get this error.
var layer = app.project.item(1).layer("layername");
var text;
if (layer instanceof TextLayer){
text = layer.text.sourceText.value;
}
else{
//...
};
But the try/catch should work too.
Xavier.

You might want to think twice before you reset your unspecified version of IE...
When you reset Internet Explorer settings, all modules and customizations are removed, and basically, you start with a new version of Internet Explorer.
The feature reset the Internet Explorer settings restores the following elements to their default settings:
- Home pages
- Search scopes
- Browsing history
- Form data
- Passwords
- Appearance settings
- Toolbars
- ActiveX controls
In addition, the feature reset the settings of Internet Explorer disables all add-ins.

"Update to 4.2 Apex - apex.widget.tabular ' is null or not an object
After the Apex 4.2 the following occurs error when loading a page that contains a list of select group [plugin]:
' *'apex.widget.tabular ' is null or not an object *.
The error seems to be related to a list item select [plug-ins] group with assigned values attributes (options) list follows:
Display the Null value: Yes
Value null, display value: -.
Return value of NULL: NULL
Note: The application requires a NULL option to display in the list of values (display = '-', value = null). It works very well in the Apex 4.1...
Remove the above values eliminates the error message. However to enter any value in the display Null value and attributes return Null value causes the error message reappear.
Is it a group select list [plug-ins] known problem/bug? Any ideas on how to work around this problem would be greatly appreciated.
THXHello
http://Apex.Oracle.com/plugins contains a version update of the plug-in the Selectlist (v1.1) group which should solve your problem. Just import it into your application and you should do.

'Length' is null or not an object for tabular forms V4 error
Hi all
We have recently updated our applications APEX of version 2 to version 4. We use many tabular forms in various applications that worked fine before the upgrade.
Since the upgrade, when we run the pages in a table we get an error JavaScript 'Length' is null or not an object and the button "Add row" everything hangs and does nothing.
We tried to remove one of the forms in table form in an application, and then re create it in the same application unsuccessfully.
We then tried to create a new application from scratch, then creating the same page (which did not work in the previous sentence) and it works well.
Of course we can just delete applications that contains a tabular form and then begin to recreate them from scratch.
Someone had a similar problem? I Googled it and a few people have mentioned similar problems with v4. Is this a bug in APEX v4?
Thank youHi Cashy,
Unfortunately, you will have to do for each application. Go to shared components
1) go to themes
(2) click on create
3) repository
(4) choose your new theme
(5) create the new theme
6) click on "change the theme.
(7) check that the mapping is ok
8) click 'Remove the theme' to remove the old themeBut to make it easier to change the templates in all your applications in the future I would say the following steps.
(1) create a new application "Main Theme" and choose the new theme you want to have.
(2) copy this application and call it "new model of demand."
3) go to shared Component\Templates
(4) for each model of defined "Reference Master model of" in the region of "Subscription" for the same model in the application "main Theme".
(5) I would also say to remove these themes you don't want that developers use in application here (eg. variations of different button model,...)
6) go to shared Component\Themes
7) click on "export theme".For each application:
1) go to Components\Themes shared
2) click on "import theme."
(3) choose your exported theme
6) click on "change the theme.
(7) check that the mapping is ok
8) click 'Remove the theme' to remove the old themeThe advantage is that if you change a model in your theme, you just make the change in your 'Main Theme' application and publish it on applications that have subscribed the theme.

After the upgrade to 4.0 earlier this week, we now have a problem with our calendars that have been built in 3.1.1. Whenever I click on a link to the event in Internet Explorer, I get the error 'length is null or not an object ". When I click on the link to Firefox, I get the error "b is undefined" comes from the apex_widget_4_0.js file. After reading for 4.0 user's guide, I've removed the region and added it with the same SQL, but I get the same error.

"'undefined' is null (or) not an object".
Hai,
I created a javascript for the date validation, code works well in Notepad for html, it is the dynamic HTML, if I run the same code in APEX it displays error saying... "'undefined' is null (or) not an object ' what does that mean?
Published by: David on October 29, 2008 03:49Hi David,
Check your logic here:
function ValidateForm(){ var dt=document.getElementById('P4_TEXT').value if (isDate(dt.value)==false){ dt.focus() return false } return true }DT is set to a value, but the if test then checks the value - because then you try to set the focus to the field, I would remove the .value "var dt..." form "line. Also make sure that all lines end with a semicolon.

Hello everyone.
I worked on a script that works on an InDesign file open with the data merge fields. During the run, the script asks the file to a directory of text files, then a directory to put the PDF files resulting. It looks like this:
#target indesign main(); var myDoc = app.activeDocument;//the indesign file that is currently open function main() { var f = Folder.selectDialog("Select the text files"); var finished = Folder.selectDialog('select folder for finished PDFs').fsName + '/'; //selects a folder to put the finished files if (f == null) return; var files = f.getFiles(); var imgs = new Array(); var file, ext; for (var n = 0; n < files.length; n++) { file = decodeURI(files[n].name); ext = file.substring(file.lastIndexOf(".")+1,file.length); if ( ext == "txt" || ext == "csv" || ext == "TXT" || ext == "CSV") { imgs.push( file ); } } for (var n = 0; n < imgs.length; n++) { var mergeTo = f.absoluteURI + '/' + imgs[n]; var pdfTo = finished + imgs[n] + '.pdf' myDoc.dataMergeProperties.selectDataSource(mergeTo); myDoc.dataMergeProperties.exportFile(finished, "[High Quality Print]", ); } }As I scroll through the script in debugging in ESTK, everything seems well of until line 22 when I get "undefined is not an object. But when I look at the data browser, everything looks like need where it is:
My thoughts are that it has something to do with the name of file used by selectDataSource referencing. But I tried dozens of permutations of the naming of files using fsName, absoluteURI, and really, I'm stuck... and have been for some time. I tried is not to worry about the forum, and I am sure that my coding must be correct, but it is obviously not. Pointers to solve this would be appreciated.

Hello
I would modify 2 lines:
1. first line with var main() statement and call after / / if think it is source of error ==> no myDoc defined
2 myDoc.dataMergeProperties.selectDataSource ( leader (mergeTo) ) / / instead of the string

BindingExpression path error: 'Orientation' not found 'object' property "ColorScale'
Hi all
A data binding error is thrown by the Debug Output window just after setting the DataSource property to certain data :
System.Windows.Data error: 40: BindingExpression path error: 'Orientation' not found 'object' property "ColorScale '(HashCode = 50862316)'. BindingExpression
ath = direction; DataItem = "ColorScale' (HashCode = 50862316); Target element is 'DependencyPropertyListener' (HashCode = 6239444); target property is 'Target' (type 'Object')I did the following:
Graph graphic = new Graph();
Graph Plots.Add (new Plot());
Graph plots [0]. Renderer = new IntensityPlotRenderer();
(Graph (IntensityPlotRenderer). Parcels [0]. Rendering engine). ColorScale = new ColorScale();
Graph DataSource = new list(); The error message is raised right after the execution of the assignment of a new list of the data source. The error seems harmless but it would be nice to understand what is causing this problem.
Thank you.
Hi, gabe0
It seems that this error occurs because the chart control is to look at his collection of scales to determine if scale orientation changes took place, but the ColorScale does not have a direction property. While you can't do anything to your program to work around this error, you can safely ignore it. I filed a bug for this behavior report.
Thanks for the comments!

Thank you
the problem is that the point is not defined when the page is created.
a solution would be to use onItemChanged to set the title.
or use something like element? Item.Name;
There are many other possible solutions, but these two come to mind that the easier.
