why setSelection doesn't work in ComboViewer? - eclipse

I have a combo, with a comboViewer in Jface,
and because is an update record dialog, I wan to sel the combo with correct selection.
I'm tryin to use
//Seleccionar Protocolo
if (fcruza.getTipoCosecha() != null)
comboProtocoloViewer.setSelection(new StructuredSelection(fcruza.getTipoCosecha()));
But the combo is not selected.
I follow java code, but I can't figure out what i'm doing wrong.
Also I have this on this control:
comboProtocoloViewer = new ComboViewer(comboProtocolo);
comboProtocoloViewer.setContentProvider (new ArrayContentProvider());
comboProtocoloViewer.setLabelProvider (new ProtocoloLabelProvider());
comboProtocoloViewer.setInput(tipoCosechaController.obtenerTipoCosecha());
Any sugestion.
Best regards

Yes ArrayContentProvider works with lists. Have you tried selecting an element as I posted earlier?
You have to make sure the element you are trying to select is part of the list, equals() of the element (fcruza.getTipoCosecha()) needs to match one of the input list.

Material.css select all option within the multiselect element

Can anyone suggest a link or solution to add select All option within the multiselect dom element of the material design. I want all the options to be selected except for the select all option and want to display it in the text field and post it.
I couldn't find a solution for it. Can anyone suggest.
Pls Note: I dont want to add it as a button outside the dom.
$("#all_member").change(function(){
if($("#all_member option[value=-1]:selected").length > 0){
$('#all_member option').attr('selected', "selected");
$('#all_member').prev("ul").find("li").addClass('active');
$('#all_member').prev("ul").find("li span input").attr('checked', "true");
}else{
$('#all_member option').attr('selected', "false");
$('#all_member').prev("ul").find("li").removeClass('active');
$('#all_member').prev("ul").find("li span input").removeAttr('checked');
}
Thanks IN advance!
I can provide the logic. The rest is up to you.
Put an onChange event handler (function) for your select.
On that function, put an "if statement" to check if the value is equal to the value of "Select All" option.
If it returns true, then manually call the element and set its value to the value of all the other options (probably an array).

Remove "empty" selection from dropdown list box

When creating a form in Orbeon Form Builder, you can define a list of values for a dropdown list box.
When running the form in form runner, is it possible to remove the "[Select...]" value from this dropdown list box?
I would like to restrict the possible values only to the given ones and restricting the user from selecting an "[Select...]" value when filling in the form. I hope you understand what I mean :)
Here is a screenshot
It's not possible without changes to Orbeon Forms to remove the empty option.
The best way to achieve what you want is to make the field required. When that's the case, the user will have to select a value or validation won't pass.
(The rationale for adding/keeping an empty option at the top is to force the user to make a selection. Otherwise it is possible that users might not even look at the option selected by default, and involuntarily select an incorrect option.)

Live search combo in Ext JS 4.2.2

I'm trying to implement a live search combo. It suppose to work like this:
When I enter a character into the combo field I read the current value and send it as a parameter to the store's url. In the backend the parameter is used to return any value from the database that contains it, so the store behind the combo gets filled only with those filtered values.
As I continue to enter characters into the combo, the parameter should be updated and sent again to the backend and so on, getting like this a smaller and smaller store.
I tryied to achieve this behaviour using the combo's event keypress, even keyup, but the problem is it's impossible for me to get access to the current value from the combo field.
For example, when I entered the "for" string into the combo, how can I obtain this value using the combo object? comboName.getValue() doesn't work, it returns nothing "".
I already saw the live combo example here: http://docs.sencha.com/extjs/4.2.2/#!/example/form/forum-search.html but doesnt help me at all.
So my big question is: how do i get the current value while still editing the combo's field?
Any help would be appreciated, thanks.
You should be able to use
comboName.getValue();
or
comboName.getRawValue();
Where comboName is your combo box. Are neither working- I note in your post you state getValues() which is an improper method. You may want to also check whether when you're referring to your combo box object, that the reference is actually correct. The first argument from the key events is actually the object itself, so you should be able to do, e.g.
listeners:{
keyup:function(comboBox){
var value = comboBox.getValue() || comboBox.getRawValue();
console.log(value);
}
}
Swapping you the value getting method as appropriate.
I found that the combo already has a quick search behaviour, I just have to set queryMode on 'remote' and some other small configurations. More details here:

Find CURRENTLY selected <option> with XPath

What's the correct XPath syntax to check if an option element is currently selected, or just to get the selected option element from a select element, on an open page with which the user, and JavaScript, may have interacted? Is this even possible with XPath, or does it lack the ability to look at DOM properties?
I can't find any documentation on this, and have (speculatively) tried:
//option[#selected=true]
//option[#selected="selected"]
//option[#selected]
but none of these work; they simply don't match any elements.
(In case it matters, I've tried this both using the $x function in the Chrome developer console, and using the find_elements_by_xpath method in Selenium for Python.)
Short answer: it's not possible.
Longer answer: XPath can look at HTML attributes, but it can't look at DOM properties. Selecting an <option> element in a <select> changes the selected property of the <option> to true, and also changes the value property of its parent <select> element, but it doesn't affect the attributes of either, so it is invisible to XPath.
To find <option> elements that have the selected attribute set, which is often how a page author might determine which option is initially selected, you can use //option[#selected]. But this does not find the currently selected <option>; changes that the user makes to the selection are invisible to XPath. There's no guarantee it will even find the initially selected option, since it's possible that the page author didn't put the selected attribute on any elements and either let the browser select the first option by default or had some JavaScript select the initial option via the selected property.
The multiple other answers here claiming that a selector like //option[#selected] can detect selection changes made by the user after the page loads are simply completely wrong.
Of course, if you're able to use CSS selectors instead of XPath selectors, then option:checked will do the job.
The problem could be the " (double quotes).
//select/option[#selected='selected'] - Will match the selected option, i am using this successfully.
//select/option[#selected='selected' and #value='specific value'] - Will only match the selected option if it has a 'specific value', i'm also using this.
If you are still having trouble, it could be an entirely different problem, perhaps there is no option node. I hope this helps.
I think we can use a knowledge from #Mark's answer and account that. Let's just find a node which HAS desired attribute:
tree.xpath('//select/option[#selected]/text()')[0].strip()
I tried "//option[#selected=''] and it has worked for me.
it is able to highlight the selected option within Page objects model.
I would try //option[#selected='true']
i.e. driver.findElements(By.xpath("//option[#selected='true']")).getText();

How to remove a validator from a Select?

I have a form where I need to add/remove validators dynamically. Based on a dropdown selection, other form fields may have different validation rules.
For other kinds of inputs, I've used replace(methodThatCreatesTheInput()) to get rid of a previously added validator. (Not knowing of a better way. Specifically, there doesn't seem to be any way to directly remove a validator from a component...)
With Select, from wicket-extensions, this approach fails with something like:
WicketMessage: submitted http post value [[Ljava.lang.String;#5b4bf56d]
for SelectOption component [8:myForm:targetInput] contains an
illegal relative path element [targetConsortiums:1:option] which does not
point to an SelectOption component. Due to this the Select component cannot
resolve the selected SelectOption component pointed to by the illegal value.
A possible reason is that component hierarchy changed between rendering and
form submission.
The method that creates the Select:
private FormComponent<?> targetSelection() {
Map<Class<? extends Target>, List<Target>> targets = targetService.getAllAsMap();
SelectOptions<Target> propertyOptions = new SelectOptions<Target>("targetConsortiums",
targets.get(Consortium.class), new TargetRenderer());
SelectOptions<Target> consortiumOptions = new SelectOptions<Target>("targetProperties",
targets.get(Property.class), new TargetRenderer());
Select select = new Select(ID_TARGET, new PropertyModel<Target>(model, "target"));
select.add(propertyOptions);
select.add(consortiumOptions);
select.setRequired(true);
select.setMarkupId(ID_TARGET);
return select;
}
(Why use a Select instead of normal DropDownChoice? We want the two types of choices to be clearly separated, as documented in this question.)
Any ideas how to solve this? What I'm trying to achieve is, of course, very simple. Unfortunately Wicket disagrees, or I'm using it wrong.
Wicket 1.4.
I don't know how to do this on Wicket 1.4, but on Wicket 1.5 there is a remove method for validators on FormComponent (see javadoc)
