Hi Farrukh,

Thanks for your reply. I moved the AjaxObserveField inside the AjaxUpdateContainer, but I'm still getting the same behavior where values that haven't just been set are set to null instead of maintaining their previous values. Any other ideas?

I can hack a solution where I just won't do anything in the setter if the value is being set to null, but the issue there is if the user deletes all the text in an input field, then the result list will not get updated to display all the values.

Thanks again for any help,

Try move the FormValuesObserveField component inside the ResultsContainer and test it.

<webobject name = "ResultsContainer">

<webobject name = "FormValuesObserveField">

<div class="formInput">First Name: <webobject name = "FirstNameFilterText"/></div>

<div class="formInput">Last Name: <webobject name = "LastNameFilterText"/></div>

</webobject>
... (list of results)
</webobject>

Hi everyone,

Sorry to be a bother, but I was wondering if anyone had any ideas for me on this issue. If it would help, I could attach a small example app that demonstrates this behavior.

Thanks for any help,

Hi all,

I am trying to create a component that displays a list of people and then lets the user filter this list based on a few criteria (first name, last name, etc.). I haven't been using ajax until very recently, so I'm sorry if this is an easy newbie question. The setup I have is I am observing multiple fields (first name input, last name input) with the same AjaxObserveField component and the AjaxObserveField updates an AjaxUpdateContainer (a repetition with the qualified result list). When I type something in just the last name input, everything works as expected. Same with just the first name input. But if I've typed something in the last name input and then I type something in the first name input, the variable storing the last name in the component gets set to null (via a setter method) and, as a consequence, the results are only qualified using the first name input. I have no idea why the value is getting set to null and I'm hoping someone can shed some light on what's going on and how to fix this issue. I'm using Webobjects 5.4.3 and a version of Project WOnder that is about a month old. Here's the relevant stuff from the component:

<webobject name = "FormValuesObserveField">

<div class="formInput">First Name: <webobject name = "FirstNameFilterText"/></div>

<div class="formInput">Last Name: <webobject name = "LastNameFilterText"/></div>

</webobject>

<webobject name = "ResultsContainer">

... (list of results)
</webobject>

FormValuesObserveField : AjaxObserveField {
observeFieldFrequency = "0.5";
observeDelay = "0.5";
updateContainerID = "results";
}

FirstNameFilterText : WOTextField {
value = firstNameFilter;
id = "firstNameFilter";
}

LastNameFilterText : WOTextField {

value = lastNameFilter;

id = "lastNameFilter";

}

ResultsContainer : AjaxUpdateContainer {
id = "results";
}

In the java file I have:

private String _firstNameFilter;

private String _lastNameFilter;

private NSArray _filteredArray;

public String firstNameFilter() {
  return _firstNameFilter;

}

public void setFirstNameFilter(String value) {
  _firstNameFilter = value;

  _filteredArray = null;

}

public String lastNameFilter() {
  return _lastNameFilter;

}

public void setLastNameFilter(String value) {
  _lastNameFilter = value;

  _filteredArray = null;

}

public NSArray allClientsAfterFilter() {
  if (_filteredArray == null) {

   EOQualifier lastNameQual = null;
   if (_lastNameFilter != null) {

   lastNameQual = ERXQ.likeInsensitive("personInfo.lastName", _lastNameFilter + "*");

   } else {
   lastNameQual = ERXQ.likeInsensitive("personInfo.lastName", "*");

   }
   EOQualifier firstNameQual = null;

   if (_firstNameFilter != null) {

   firstNameQual = ERXQ.likeInsensitive("personInfo.firstName", _firstNameFilter + "*");

   } else {
   firstNameQual = ERXQ.likeInsensitive("personInfo.firstName", "*");

   }

   EOQualifier qual = ERXQ.and(lastNameQual, firstNameQual);
   _filteredArray = EOSortOrdering.sortedArrayUsingKeyOrderArray(EOQualifier.filteredArrayWithQualifier(allClients(), qual), null);

  }
  return _filteredArray;
}

Thanks for any help on this.
