ComboboxItem setAllowExpressions don't work!

[Hock]

Hello,
i use

 SmartClient Version: v10.0p_2015-04-21/PowerEdition Deployment (built 2015-04-21)

on firefox 24.3.0.

I create a combobox as follows:

ComboBoxItem cbi = new ComboBoxItem();
cbi.setOptionDataSource(DataSource.get("optionDataSource"));
ListGridField lgf1 = new ListGridField("lgf1", "lgf1");
ListGridField lgf2 = new ListGridField("lgf2", "lgf2");
cbi.setPickListFields(new ListGridField[]{lgf1, lgf2});
cbi.setAllowExpressions(true);

and set it to ListGridField

 
ListGrid lg = new ListGrid();
lg.setOptionDataSource(DataSource.get("dataSource"));
ListGridField lgf = lg.getField("optionField");

lgf.setFilterEditorProperties(cbi);

So I get combobox in filter editor. But if I use expressions in this field no data is shown.
Any idea what going wrong or which settings must be done aditionally?

With best regards

This is by design - we would consider this a clashing and confusing mixture of two different UIs, as the entire interface of a ComboBox is dedicated to displaying iteratively filtered results, and that doesn't work with operators like "endsWith" or "greaterThan".

We'd recommend just leaving this as a text field if you want to enable the allowExpressions feature.

However, if you really wanted to implement this, you could use a getPickListFilterCriteria function to return criteria based on parsing the user input yourself, for the few operators that might make sense. Or, you could build a control that allows the end user to switch on the fly between using a ComboBoxItem vs picking a specific operator and using a plain TextItem for input.

Thank you for your reply.

I will try to write a own parser for expressions.

I have implemented FormItemCriteriaFunction and its work fine for comboboxitem picklist. So if I enter expression picklist shows records that match expression. That is what I need. Since combobox is used in listgirds filtereditor I want filter with same expression in listgrid if I enter filter button.

How can I realize this?

Hello Isomorphic,

should I create new thread for my second issue in relation to combobox?
