    <p>I'm looking for a solution where I would like to filter my container with multiple values using logical OR.</p> <p>For instance, I would like to filter my value and get the result where value == "A" or "B"</p> <p>This piece of code works when I only have 1 value :</p> <pre><code>private void applyTextFilters(List&lt;String&gt; filters) { unselectAllItems(); IndexedContainer container = (IndexedContainer) valuesTable.getContainerDataSource(); container.removeContainerFilters(Columns.SEARCH.id()); for (String filter : filters) { container.addContainerFilter(Columns.SEARCH.id(), filter, true, false); } clinicalValuesGraph.refreshGraph(container, getLabel("clinicalvalues.graph.caption")); // if it is the case ... //toggleEmptyResultNotification(); handleView(viewMode); } </code></pre> <p>What am I missing? Again, if I have 2 filters ("A","B") in my code, none of the results show but if I pass "A", it works.</p> <p>To follow with my question...</p> <p>Using 6.5.7, I need to filter my container with 2 criterias as in search names like "patrick" OR "john".</p> <p>I've inspected the code and this is where I would need to modify a method (which is protected) :</p> <pre><code>protected boolean passesFilters(Object itemId) { IndexedContainerItem item = new IndexedContainerItem(itemId); if (filters == null) { return true; } final Iterator&lt;Filter&gt; i = filters.iterator(); while (i.hasNext()) { final Filter f = i.next(); if (!f.passesFilter(item)) { return false; } } return true; } </code></pre> <p><strong>TO THIS :</strong></p> <pre><code>protected boolean passesFilters(Object itemId) { IndexedContainerItem item = new IndexedContainerItem(itemId); if (filters == null) { return true; } boolean previouslyPassedFilter = false; boolean PassesFilter = true; final Iterator&lt;Filter&gt; i = filters.iterator(); while (i.hasNext()) { final Filter f = i.next(); if (!f.passesFilter(item) &amp;&amp; !previouslyPassedFilter) { passesFilter = false; } else { previouslyPassedFilter = true; } } return passesFilter ; } </code></pre> <p>How would that be done without having to rewrite all of these classes (IndexedContainer, IndexContainerItem...) ?</p>

    1. COI think you would need to switch to Vaadin 6.6+. It ships with filters located in `com.vaadin.data.util.filter`, among which there is `Or`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
