This is my Grid, which loads dynamically. whenever it changes, all the records from the grid should be retrieved, where i can easily export it to Excel.
Just i want is all the records in the grid eighter as an array or list, is there any listener to handle it or any way i can get all the records.
I have tried out in some ways by adding a listener to a store by it does not gives me result
Did you try-
store.getAll(); ?
This code takes all the records in the grid and returns as a collection. However, you may need to take another arrayList to use the store values depending on your needs.

we still have Jackrabbit 2 (2.18.0) in use and I have a problem with loading the "jcr:path" in the Query-Result.
In this example we have a custom node "org:permission" with a custom property "org:permissionHolderIds".
The custom property is filled in values in the found rows.
String queryString = "SELECT [jcr:path], [org:permissionHolderIds] FROM [org:permission]";
QueryManager queryManager = session.getWorkspace().getQueryManager();
Query query = queryManager.createQuery(queryString, Query.JCR_SQL2);
QueryResult queryResult = query.execute();
RowIterator rows = queryResult.getRows();
Row r = rows.nextRow();
String holder= r.getValue("org:permissionHolderIds").getString();
// is filled properly
String path = r.getValue("jcr:path").getString();
// path is empty all the time :-(
Until now we iterated over the found nodes but this causes additional data base queries and is slow. So we tried to improve our performance and fetch all the necessary data in the query.
Thank you!
jcr:path is not a node property, so this is not supposed to do what you want. That said, why don't you use https://docs.adobe.com/docs/en/spec/javax.jcr/javadocs/jcr-2.0/javax/jcr/query/Row.html#getPath()?
I have a requirement in which I have an af:query panel which after querying populates an af:table.
Now based on the table rows when any 1 row is selected, the graphs below it should be populated based on some columns.
Now my problem is that on search when the table is populated for the first time, no row is selected.
I need the first row to be selected automatically. I have searched multiple solutions from the net forums but till now haven't found any working solution.
Please help me what code should I use to select a row programmatically. and also where should I put this code in the backing bean.
As you've correctly mentioned, at the first render of the table no row is selected. I've encountered this problem too, and i've dealt with it by calling a getting the first row of the corresponding VO on BeforePhase (i.e: on the page first rendering or refresh).
I understand that you intend to do so for the first searching.
The af:query component has a property called QueryListener. You can link it with a method inside a backing bean. The content should be like:
private QueryEvent qEvent = null;
public void queryListener(QueryEvent queryEvent) {
setQEvent(queryEvent);
JSFUtils.invokeMethodExpression("#{bindings.YourViewObjectNameViewCriteriaQuery.processQuery}", Object.class,
QueryEvent.class, getQEvent());
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry(); //Edited
DCBindingContainer bc = (DCBindingContainer)bindings;
DCIteratorBinding iterator = bc.findIteratorBinding("YourViewObject1Iterator");
Row r = iterator.getCurrentRow(); //Here you've got the very first row, and can operate with it
.....
}
public void setQEvent(QueryEvent qEvent) {
this.qEvent = qEvent;
}
public QueryEvent getQEvent() {
return qEvent;
}
With this, you should be able to get the first row when the query is executed (i.e: when the search is done).
After getting the first row, you can programmatically the graph process execution or whatever you do.
NOTE: invokeMethodExpression can be found inside JSFUtils, which is a starndard class with static methods which source code you can download here: JSFUtils.java
I've been searching for hours but I couldn't find an answer to my question: I've set up a ListGrid similar to the one shown here (Link). Right now I am using a XML-File as data source (default rows) just like in the example. It is also possible to add and delete rows to/from the grid.
Therefore I would like to store every user's data from the grid in a data store (Google Datastore). So I need to read all the rows of the current user as Strings. What would be a good way to do that? I already tried the following, but without success:
ListGrid componentsGrid = new ListGrid();
componentsGrid.setWidth(500);
componentsGrid.setHeight(224);
componentsGrid.setCellHeight(22);
componentsGrid.setDataSource(ComponentsXmlDS.getInstance());
componentsGrid.setAutoFetchData(true);
componentsGrid.setCanEdit(true);
componentsGrid.setModalEditing(true);
componentsGrid.setEditEvent(ListGridEditEvent.CLICK);
componentsGrid.setListEndEditAction(RowEndEditAction.NEXT);
componentsGrid.setAutoSaveEdits(false);
layout.addMember(componentsGrid);
//First try
componentsGrid.fetchData();
logger.log(Level.INFO, "Components: "+ componentsGrid.getResultSet().get(0).getAttribute("componentType"));
//Second try
logger.log(Level.INFO, "Components: "+ componentsGrid.getAllFields());
// Third try
logger.log(Level.INFO, "Components: "+ componentsGrid.getRecords());
Anyone having a hint? Help is greatly appreciated.
If I understand well your requirement you want to read all the rows of the grid and store their data in a db.
I think you can use:
getRecordList() which *Return the underlying data of this DataBoundComponent as a RecordList.
You will be able to iterate inside this list, extract the attribute value you want for every record and store these data in your db.
Or use the getRecords() method as you said and iterate in the array of ListGridRecord obtained.
To iterate through your RecordList you have to transform it to an array, for example with a lot of dummy objects and methods:
RecordList data = MyGrid.getRecordList();
for(Record record : data.toArray()){
MyDataObject obj = new MyDataObject()
obj.setId(record.getAttribute("thId"));
obj.setOne(record.getAttribute("anAttribute"));
obj.setTwo(record.getAttribute("anotherAttribute"));
obj.StoreToDb();
}
I need is to dynamically add the points I’ve received from a forex provider to s Shield UI Chart. According to the documentation, there isn’t the possibility for dynamically adding of points At least there is no such method, something like: AddPoint or similar.
How can I still achieve a web page using Shield UI Chart, which to constantly show a couple of exchange rates?
You are right, that there is no addPoints method of the Shield UI Chart. However we can add the incoming data values to an array instead. You might find useful following code:
We need some arrays- as many as we need to show.
var EURUSD = new Array();
var USDCAD = new Array();
var GBPUSD = new Array();
In the body of the function, that will actually display the data we will have the following code:
EURUSD[EURUSD.length] = parseFloat(data.ticks.EURUSD);
USDCAD[USDCAD.length] = parseFloat(data.ticks.USDCAD);
GBPUSD[GBPUSD.length] = parseFloat(data.ticks.GBPUSD);
it will actually put the new data to the designated arrays. You can note, that each time data is received, it has been added to the last index of each array:
EURUSD.length
Since we don’t want our arrays to grow too large, it is good to specify how many points we need to keep. Once that limit is reached, we remove the oldest point:
if (EURUSD.length > 50)
EURUSD = EURUSD.splice(1, 49);
if (USDCAD.length > 50)
USDCAD = USDCAD.splice(1, 49);
if (GBPUSD.length > 50)
GBPUSD = GBPUSD.splice(1, 49);
At the end we need to recreate the chart, referencing the appropriate container:
var containter = $("#EURUSDChart").swidget();
containter.destroy();
and than create the chart again.
I'm using a parent to pass a multi-dimensional array to a child. Structure of the array, named projectPositions is as follows (with example data):
projectPositions[0][0] = 1;
projectPositions[0][1] = 5;
projectPositions[0][2] = '1AD';
projectPositions[0][3] = 'User name';
I need to take this inherited array and turn it into an arrayCollection so that I can use it as a dataProvider. Currently, my init function (which runs onCreationComplete) has this code in it to handle this task of array -> arrayCollection:
for (var i:int = 0; i < projectPositions.length; i++)
{
tempObject = new Object;
tempObject.startOffset = projectPositions[i][0];
tempObject.numDays = projectPositions[i][1];
tempObject.role = projectPositions[i][2];
tempObject.student = projectPositions[i][3];
positionsAC.addItemAt(tempObject, positionsAC.length);
}
Then, during a repeater, I use positionsAC as the dataprovider and reference the items in the following way:
<mx:Repeater id="indPositions" dataProvider="{positionsAC}" startingIndex="0" count="{projectPositions.length}">
<components:block id="thisBlock" offSet="{indPositions.currentItem.startOffset}" numDays="{indPositions.currentItem.numDays}" position="{indPositions.currentItem.role}" sName="{indPositions.currentItem.student}" />
</mx:Repeater>
This all works fine and returns the desired effect, but the load time of this application is around 10 seconds. I'm 99% sure that the load time is caused by the array -> arrayCollection for loop. Is there an easier way to achieve the desired effect without having to wait so long for the page to load?
The issue your having loading items could be because you are using a repeater instead of a list class.
With a repeater, there will be a block created in memory, and drawn on the screen. So, if you have 100 items in your array, then 100 blocks will be created. this could slow down both initial creation and the overall app.
A list based class focuses on a technique called renderer recycling; which means only the displayed elements are created and rendered on the screen. So, depending on settings, you'd usually have 7-10 'block' instances on the screen, no matter how many items you have in your array.
change
positionsAC.addItemAt(tempObject, positionsAC.length);
to
positionsAC.addItem(tempObject);
addItemAt is causing a reindex of the collection which can greatly slow down the collection.
[EDIT]
Put this trace statement before and after the loop
take the output and subtract one from the other and that will show how many milliseconds the loop has run.
var date:Date = new Date( );
trace( date.getTime())
