is it possible in a ListSelectionDialog in eclipse to pre select some of the entries?
and if so, how do I select them?
Call setInitialSelections with an array containing the objects you want to select. This must be done before calling open.

I have a pre-formed Zend_Db_Select which already utilized columns() method.
I need to add another column to select. Executing columns() again replaces the previous one, so I lose the previously selected columns.
Modifying the select I recieve is not possible.
How to add another column to an existing Zend_Db_Select which already incorporates columns() method? Is it possible without parts surgery?
I have a question about APEX, I have the problem that when I try to select a value from a selectbox, no value shows in the other items. What I have tried to do is loading data from the database to the items when I select a code from the selectbox with PL/SQL. How do I do this? Selecting a code from a selectbox and filling all the other items?

Ok if i understand you right you need a List of Values.
If you create this shared Object. Use a dynamic list.
There you have a dialog you can put a PL/SQL or SQL Code snippet into.
You must return a 2 column list. The first Column is the field name in you later select box and the second is you reference.
when i select index 0 then all Previously selected item should be remove. Is this possible? i have multiple chosen drop down in same page...i have tried so many things but didn't get the proper solutions yet.
I am not sure what you mean. If it is multiple select, it means you can select "multiple" items, otherwise it's a normal select. Also see this and check out if it provides something helpful for you.
I´m using GWT 2.4 with a DataGrid and a SimplePager along with a MultiSelectionModel. I want to implement a simple select-all-feature over all pages.
I´m only able to select all visible items on the current page. What is the best way to select all items on all pages?
I know the MultiSelectionModel stores the proxy keys provided by a ProvidesKey object in a HashMap. I think I have to request all proxy objects from server or at least all keys. But actually I don´t want to store information about the ProvidesKey´s getKey()-method on server-side. But I also can not access the MultiSelectionModel´s HashMap of the selected proxies´ keys. This all looks cumbersome, so is there a better way to solve this?
As mentioned in https://developers.google.com/web-toolkit/doc/latest/DevGuideUiCellWidgets#selection, one way to achieve this would be to implement your own SelectionModel (e.g. by extending AbstractSelectionModel or DefaultSelectionModel):
A complex implementation can handle "select all" across multiple pages using a boolean to indicate that everything is selected, and then keep track of negative selections.
Why do you need all keys for select all? When you select some objects from a list, you need to remember which ones are selected, but when you select all objects, you need a single Boolean:
// on click Select All button/checkbox
boolean selectAll = true;
// ask a user what he wants to do
// send a request to server with a parameter selectAll to update/delete all objects
Select all across multiple pages will work only if you are NOT lazy loading. First of all why do you need to select all? If you want to do some actions on all the grid data, you will already have the list and you can perform your actions on the list directly. Nonetheless you can select all the rows of the grid over multiple pages by iterating through the list and using the following API on each item.
public void setSelected(T item, boolean selected);
Note: This will work only if you are NOT lazy loading.
I have 2 select, I want the second select list loads based on selected value of first select. In another word first select is a list of objects, those objects each has a list of another objects. so I want load second list based on selected object of first select. I know that can be done using JQuery, but can I do this without JavaScript/JQuery?
Thanks in advance.
There is a tag that does this for you http://struts.apache.org/2.x/docs/doubleselect.html
Out of the box it probably uses Dojo API or uses a server side request to generate the second list. I have not used any of the JQuery UI in Struts.
No, you can't do this without Javascript. With static HTML you can't achieve this effect; drop-down fields on HTML forms come pre-loaded with their options, and are independent of other fields on the form.
