Porting 0.4 Combobox with dataUrl to 0.90

In Dojo 0.4 I had a Combobox with the dataUrl set to an url that returned a list of logged on users. The Combobox pulled data from the url each time the drop down arrow was pressed, so it was always up to date. With Dojo 0.9, I`ve set the Combobox to use a datastore, but it only pulls data from the url the first time it is clicked. How can I get it updating every time it is clicked like with Dojo 0.4?

Thanks in advance..

I have the same problem

Basically I have the same problem regarding upgrading comboBox 0.4 to comboBox 0.9. With comboBox 0.4 for Auto Complete, for every character entered in the Text box, a request is being sent to the data provider; in my case I was able to send a request to the Servlet with a parameter that determines my search string dataUrl="/actions/someJSP.jsp?skills=%{searchString}" for example if someone types the character “a” a request is being send the servlet and it would return a JSON file containing all string starting with character “a” which is what I really need, … however with Dojo 0.9 comboBox it seems there is a single call to the data provider and it populates your list and there are no subsequent calls to the data provider, now how would I be able to call the data provider ( jsp/ servlet any server call) for every character that is typed in the input box. Thanks.

I was able to find a workaround until this issues is fixed, basically I modified JsonItemStore and make sure for every character that is entered in the input box the JsonItemStore does a remote call and retrives the value base on the parameter. I’m using a JSP or Servlet file in a remote server. Basically the JSP or Servlet will get the param and based on the param name and value will return a JSON file format back( make sure you use JSON format for dojo version 0.9), for example if I have a input box for states and the user types “c” my server would return the following format string:

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

"{identifier:'abbreviation', items: [{name:'<?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />California',abbreviation:'California'},{name:'Colorado',abbreviation:'Colorado'},{name:'Connecticut',abbreviation:'Connecticut'}]}"

( you may want to rename the JsonItemStore, but make sure you make the correct reference to it)

Here is my html code

</div>

<input dojoType="dijit.form.ComboBox"

store="stateStore"

searchAttr="name"

name="state1”

( you will have to append the Param value to the url in the JsonItemStore.js)

Modify JsonItemStore.js _fetchItems: function

Simply remove this code starting line number 243 to 246

if(this._loadFinished){

filter(keywordArgs, this._arrayOfAllItems);

}else{ // make sure you remove the close ‘}’ at the end

Replace the above code by retrieving the argument or what the user has typed in

keywordArgs.query[key] // need to replace key with a way to see the first element

also you may want to remove the “*” at the end of keywordArgs.query[key]

var va = value.lastIndexOf('*');

value = value.substr(0, va);

then finally modify line 249

from url: self._jsonFileUrl

to url: self._jsonFileUrl + value // value is the string type in input box

I hope this helps

Thanks.

The same problem

I have the same problem. I can't upgrade to 0.9 without possibility to have active 'finder' - I am querying against 100k records so I can't do it on client site. Any progress in implementing server side filtering in 0.9 ? Thanks.
