Possible bug in ListGrid display when using Field with setPickListFields

[Blama]

Hi Isomorphic,

I found a weird bug when I tried to integrate you example http://www.smartclient.com/smartgwt/...bobox_category in my project.

I use a bound ListGrid and want to display many columns of my optionDataSource, so I use "setPickListFields(...)".

This is my code:

		boundList = new ListGrid();
		boundList.setFields();

		final ListGridField anredeIdLGF = boundList.getField("ANREDE_ID");

		final DataSource anredeDS = DataSource.get("T_ANREDE");
		anredeDS.setCacheAllData(true);

		ComboBoxItem anredeIdCBI = new ComboBoxItem() {
			{
				setOptionDataSource(anredeDS);
				setValueField("ID");
				setDisplayField("NAME");
				
				ListGrid ddLG = new ListGrid() {
					{
						setDataSource(anredeDS);
						setFields();
					}
				};
				setPickListWidth(400);  
				setPickListFields(ddLG.getField("SHORTNAME"), ddLG.getField("NAME"), ddLG.getField("DESCRIPTION"));
			}
		};
		anredeIdLGF.setEditorType(anredeIdCBI);

What happens is that the Dropdown changes its design as you can see in the attached pictures. Note on pictures 3,4 and 5 how the design of the Dropdown changes from no header to header to header with correct width (width given in ds.xml file).

<DataSource schema="mySchema" dbName="Oracle" tableName="T_ANREDE" ID="T_ANREDE" dataSourceVersion="1"

	serverType="sql"
>
	<fields>
		<field primaryKey="true" hidden="true" name="ID" type="sequence"></field>
		<field name="SHORTNAME" title="Kurzform" length="20" type="text" width="50"></field>
		<field name="NAME" title="Ausgeschrieben" length="50" type="text" width="100"></field>
		<field name="DESCRIPTION" title="Beschreibung" length="100" type="text" width="250"></field>
		<field name="MODIFIED_BY" hidden="true" type="int"></field>
		<field name="MODIFIED_AT" hidden="true" type="datetime" title="Geändert"></field>
	</fields>
</DataSource>

I'm on the 3.0 eval with FF 9.0.1 and tried both development mode out of Eclipse Indigo SR1 as well as deployed to Tomcat 7 (all on local Win7).


Can you confirm the report?
Do you need more code?

"width" is not a valid setting in a .ds.xml file - note how it is not documented there. Just because you see a property has *some* effect does not mean it is supported - use the docs.

Hi Isomorphic,

I removed the "width" attributes, but the behaviour keeps the same.
I also noticed I get warnings related to this like "IFCS6:WARN:PickListMenu:isc_PickListMenu_10:fields and completeFields are null and there is no DataSource", but the widgets work as expected.

Best regards,

Since there are samples showing this behavior working fine, you should work toward a minimal, standalone test case and fill out the other information in the FAQ.

Hi Isomorphic,

I found the error. It was the way I got my ListGridField for setPickListFields(...)

Correct:

				        ListGridField shortname = new ListGridField("SHORTNAME");
				        ListGridField name = new ListGridField("NAME");
					setPickListFields(shortname, name);

I did:

				ListGrid ddLG = new ListGrid() {
					{
						setDataSource(titelDS);
						setFields();
					}
				};
				setPickListWidth(200);
				setPickListFields(ddLG.getField("SHORTNAME"), ddLG.getField("NAME"));

Thank you,
Blama
