AF:treeTable want to expand all of the nodes.
HelloI use jdeveloper Studio Edition Version 11.1.1.3.0
I have af:treeTable. I want to expand all nodes after clicking on af: commandButton. How can I do this?
< af:treeTable value = "#{bindings.department2.treeModel}" var = 'node' "
selectionListener = "#{bindings.department2.treeModel.makeCurrent} '"
rowSelection = "single" id = "tt1" initiallyExpanded = "true" > < f: facet name = "nodeStamp" >
< af:column id = "c2" >
< af:outputText value = "#{node}" id = "ot2" / >
< / af:column >
< / f: facet >
< f: facet name = "pathStamp" >
< af:outputText value = "#{node}" id = "ot3" / >
< / f: facet >
< / af:treeTable >
If I used initiallyExpanded = true. It expand only the first node.i want to expand any swelling after clicking on the button.
For all nodes in a treetable can be expanded, you will need to add all the rows of the disclosedRowKeySet.
(1) create a binding for the treetable in average managed code as "treeTable.
(2) in the actionListener for the commandButton control, call the following method 'expandTreeTable ':
{} public void onExpandButtonClick (ActionEvent actionEvent)
this.expandTreeTable ();
}
private RowKeySet disclosedTreeRowKeySet = new RowKeySetImpl();
private void expandTreeTable() {}
Private Sub expandTreeChildrenNode (RichTreeTable, rt,
Thank you
If (this.treeTable! = null) {}
disclosedTreeRowKeySet = new RowKeySetImpl();
Model CollectionModel = (CollectionModel) treeTable.getValue ();
JUCtrlHierBinding = treeBinding
(JUCtrlHierBinding) model.getWrappedData ();
JUCtrlHierNodeBinding RootNode = treeBinding.getRootNodeBinding ();
disclosedTreeRowKeySet = treeTable.getDisclosedRowKeys ();
If (disclosedTreeRowKeySet == null) {}
disclosedTreeRowKeySet = new RowKeySetImpl();
}
List
rootNode.getChildren ();
for (node JUCtrlHierNodeBinding: firstLevelChildren) {}
List ArrayList = new ArrayList();
List.Add (node.getRowKey ());
disclosedTreeRowKeySet.add (list);
expandTreeChildrenNode (node, treeTable, list);
}
treeTable.setDisclosedRowKeys (disclosedTreeRowKeySet);
}
}
JUCtrlHierNodeBinding node,
The list
ArrayList children = node.getChildren ();
List
If (children! = null) {}
for (int i = 0; i)< children.size();="" i++)="">
rowKey = new ArrayList ()
rowKey.addAll (parentRowKey);
rowKey.add (((JUCtrlHierNodeBinding) children.get (i)) .getRowKey ());
disclosedTreeRowKeySet.add (rowKey);
If (((JUCtrlHierNodeBinding) (children.get (i))) .getChildren () is
null)
continue;
expandTreeChildrenNode (rt,
(JUCtrlHierNodeBinding) (node.getChildren () .get (i)),

Best way to expand all of the Illustrator file to allow bleeding?
Hi all:
I work in AI CS6
I'm new to Illustrator and created a document (30 + layers) layered with a photo embedded as the background layer. I have implemented the work plan with a margin to bleed early in the project... but just realized I ever expand the image to fill this bleeding edge. I tried to use the slice tool to select the entire project and Shift-Dragiing the corner evolve... it the tiny distance to the edge of the border of purge but elements in the design etc. team.
Is there a way to foolproff to do what I'm missing? Thanks in advance for any help...
The image can be larger than the size of the canvas. If you paste a picture which is 2000x2000px in a document of 1000x1000px image is always at its original size until it gets cropped. If you go into 'Size of Image', which is the measure of the final output image/document.All you need to do is select 2 transparent sides and then perform content aware fill on their work then fact! Save and replace in Illy. -
I want to check all of the included images are properly related to my work.
Hello
I'm sorry to bother you with my question, but I hope that you will be able to answer me.
The real thing is, what I did on Windows 8.1 Adobe InDesign CC includes a link to each image starts with E: / / or something.
Because I want to make it universal, and Mac does not use E: / / for example, I need to know if there is a way to make the links in these 2 platforms.I do not know. Maybe somehow the links in the format like: "*/folder/links/picture.jpg."
Thank you for your time.
Kind regards
CeciliaInDesign uses the absolute paths for links with the exception that if the link is not found in the specified path ID will search the current folder where the .indd file is stored and all subfolders and use the links he discovered there.

expand all the nodes in an af:tree component
Hello
We use the ADF 11 g. In a one of our pages, we use an af:tree control and we want to show all nodes developed by default. How to get there? "Expand all" in the menu contextual works only for the current node.
Thank you.

new to labview :-) and I have a problem when I want to change the value of a string in bunches, and I want to implement this using the node value of property instead of writing directly to the stream or by using the variable, enclosed is the picture. No matter, I have change in cluster (control) or value of Popery out (indicator) cluster, the value (sensor 7) dataflow keeps unchanged even I gave the new value by value of property node. Thank you to give me some advice about this.
Hi GerdW
Thanks a lot for your answer. The reason I'm stubbornly tring to break the flow of DATA is: we have a test system that have about 100 screws, they have a few connected flow, some of them will be unbundling a cluster dataflow chain to check the value in order to make the different cases. Now I want to insert user event by changing the control and influential cases during run time.
As I initially uses a global variable (to control cases) instead of unbundle string data flow, it works well. But then, I found there are a lot of screws that are using the string unbundle. One of the 'lazy' means, I tried is to change the value via the property node (because that way, I did not need to find all the places where using the unbundle string and replace them with the global variable), then I noticed a problem with "dataflow", the value in the stream of cluster in fact will not be changed by changing the value of the property node.
I did a test with VI simple (like the picture in last post), and after reading your advice, I tell myself that I need to understand the concept of "DATAFLOW" in labview, it seems that my "lazy" way can not work in this scenario.
I have attached the criterion VI here, have you furthur suggestions on what I can do in this case?
Mant thanks!

E4X: Select the nodes that match a criterion, and whose children match to another
Hi guys,.
I'm writing a query of E4X to select the nodes that match a criterion, and whose children match to another. My actual dataset is a little more complex than this example, but this one is easy to follow.
Say that you are modeling a hierarchy of nodes, where each node can have zero or more parents and children. The XML file is a simple index of nodes, and each node contains their immediate parent and child relationships. In this way, you can start with a given node and build a tree in a direction any to any depth. As an extra flavor and selection criteria, each node has one or more colors that are associated with.
Here's a sample:
nodes <>
< node id = ' a' >
< name color = "red" / >
< child id = 'b' / >
< / node >
< node id = "b" >
< name color = "red" / >
< name of color = "green" / >
< parent = 'a' / >
< child id = "d" / >
< / node >
< = 'c' node id >
< name color = "blue" / >
< name of color = "green" / >
< child id = "d" / >
< / node >
< node id = "d" >
< name of color = "green" / >
< id parent = 'b' / >
< id parent = 'c' / >
< / node >
...
< / node >
Now, say I want to select all nodes root (those who have no parent relationships) that are red. This is the best I could come up with:
var nodeChildren:XMLList = nodeData.node. (! hasOwnProperty ('parent'))... Color. (@name == "red");
for each {(var childData:XML in nodeChildren)
var childID:String = nodeData.parent () .@id;}
}
The first line gets us 90% of the way by selecting all of the nodes of color matching, but we have all these entries to get the id of the node that contains.
It is possible to select the nodes in one of the E4X without needing the loop?
Thank you!
Scott
So how about this?
nodeData.node. (! hasOwnProperty ('parent') & color.) (@name=="red").length () > 0)

Expand all the nodes in a tree table
Hello
I have a tree table in my JSPX, which needs to expand all its nodes when the page is loaded. Also mis the data control is a POJO data contrl where I have a collection (ArrayList), which serves to make this table from the tree. Tree table is displayed as expected with it of the child nodes.
I was referring rare item such as these... https://blogs.oracle.com/jdevotnharvest/entry/how_to_programmatically_disclose_a to expand all nodes. But I get an exception of cast of class on the piece of code following
Code:
CollectionModel model = (CollectionModel) your_af_tree_reference.getValue();
Exception:
javax.faces.el.EvaluationException: java.lang.ClassCastException: oracle.adfinternal.view.faces.model.binding.FacesCtrlHierBinding$FacesModel cannot be cast to oracle.adf.view.rich.model.CollectionModel at org.apache.myfaces.trinidad.component.MethodExpressionMethodBinding.invoke(MethodExpressionMethodBinding.java:51)

The new "address book all the ' that you correctly identify occupies the site higher in the list.
Currently there is no way to set a default value, because there has never been anyone want one so far.

Replacement of the main computer, don't want to lose all the data synchronized.
I use Firefox Sync with multiple devices at work and at home. My main computer, which is the original pc all data from first and I use to add new devices, is my work laptop. I'm being transferred across the country and no longer have this laptop.
I need somehow put up my home pc or my new laptop to work as the new main computer, but I don't want to lose all data. Should I export all the data from the laptop the existing work and import it on the new pc, then installed Sync all over again on my other devices (Mercury browser for iphone and ipad)? Or is there an easier way to do it?
Thank you
JakeHello, first of all please create a backup of your profile of your work pc folder, so that you have your data available in all cases: back up and restore the information contained in the profiles of Firefox
I do not think that there is something like a 'primary' feature in your accounts sync - all devices need to be at the height, you can simply delete your old laptop to sync & add the new laptop to the account:
Go to firefox > options > tab sync on your old laptop. Please make sure you as your user name, password of the account and the recovery key is known to you (you can access the recovery key under 'manage accounts' "-write it down if you haven't done so already '), then click on separate device in the Synchronize tab.You can then add your new laptop to work on behalf of sync existing either by coupling a device while you're close to your pc at home or with your user account, password and recovery key.

This is how it should look.

I have just three pictures I want to load my usb for my macbook camera style.
The camera has only 3 pictures on it, but iPhoto seems to have a memory of each photo, that I took because I've updated to the latest iPhoto and it wants to load on the page which is for the camera.
