Hi everybody,
I am just new to GWT and experiencing a little bit with SmartGWT,
implementing and trying to change the Tile Sort & Filtering Example
from the Showcase
http://www.smartclient.com/smartgwt/showcase/#featured_tile_filtering
I am trying to implement the above example with a fuzzy search but
without the extra SearchItems, which causes the FuzzySearch to fail
and draw back on an EQUALS search.
Everything works fine with the example, but here comes my 'error' /
'bug' :
Here is an excerpt from the code from the showcase example:
<code>
final DynamicForm filterForm = new DynamicForm();
filterForm.setIsGroup(true);
filterForm.setGroupTitle("Search");
filterForm.setNumCols(6);
filterForm.setDataSource(AnimalXmlDS.getInstance());
filterForm.setAutoFocus(false);
TextItem commonNameItem = new TextItem("commonName");
SliderItem lifeSpanItem = new SliderItem("lifeSpan");
lifeSpanItem.setTitle("Max Life Span");
lifeSpanItem.setMinValue(1);
lifeSpanItem.setMaxValue(60);
lifeSpanItem.setDefaultValue(60);
lifeSpanItem.setHeight(50);
lifeSpanItem.setOperator(OperatorId.LESS_THAN);
SelectItem statusItem = new SelectItem("status");
statusItem.setOperator(OperatorId.EQUALS);
statusItem.setAllowEmptyValue(true);
filterForm.setFields(commonNameItem, lifeSpanItem,
statusItem);
filterForm.addItemChangedHandler(new ItemChangedHandler() {
public void onItemChanged(ItemChangedEvent event) {
tileGrid.fetchData(filterForm.getValuesAsCriteria());
}
});
</code>
Three search items are created and fit together in the filterForm.
Using the form and entering just a part of a Common Name, will break
down the results with each letter I type.
Now comes the bad part:
I do not want the lifeSpanItem and statusItem any more. So I change
<code>
filterForm.setFields(commonNameItem, lifeSpanItem, statusItem);
</code>
to
<code>
filterForm.setFields(commonNameItem);
</code>
Now, trying to enter just a part of a Common Name will not break down
my results with each letter I type, but instead the behaviour is like
commonNameItem.setOperator(OperatorId.EQUALS)
So what I am saying is that the search works fine for searchItems
greater than just one TextField. My workaround therefore was to create
a HiddenItem as follows:
<code>
HiddenItem tagsItem = new HiddenItem("tags");
tagsItem.setOperator(OperatorId.EQUALS);
filterForm.setFields(commonNameItem, tagsItem);
</code>
Now I think that this can't be right. Now am I missing something? Do I
have to use .setOperator on commonNameItem, if only commonNameItem is
present? If yes: Which OperatorId should I choose?
Thank you very much for your help,
Greets,
Jan
