Deleting a node having input field from TreeTable

[Darac]

Hi,

I have a TreeTable that has inputText fields for each node. Next to the inputText there is a button that, when clicked, is supposed to delete the node:

Code: Select all

        <p:treeTable id="main-tree" var="n" ...>

            <p:column>
                <f:facet name="header">Name</f:facet>
                <h:outputText value="#{n.name}"/>
            </p:column>

            <p:column>
                <f:facet name="header">Value</f:facet>
                <p:inputText value="#{n.value}"/>
            </p:column>

            <p:column>
                <p:commandButton icon="ui-icon-minus" process="@this" update="main-tree" action="#{model.removeListEntry(n)}"/>
            </p:column>

        </p:treeTable>

Node is being deleted like this:

Code: Select all

    public void removeListEntry(NodeData nodeData) {
        TreeNode treeNode = nodeData.getTreeNode();
        assert treeNode != null;
        // Clear children
        treeNode.getChildren().clear();
        // Deatch from parent
        treeNode.getParent().getChildren().remove(treeNode);
        treeNode.setParent(null);
    }

The problem is that an exception is thrown upon deletion:

Code: Select all

Any suggestions, should I do deletion differently? What am I doing wrong?

i confirm this issue. other users report this problem too:

viewtopic.php?f=3&t=22551&p=69044&hilit ... ror#p69044

after changing a tree structure programatically, exceptions like this occur if e.g. selecting a node:

Code: Select all

INFO: java.lang.IndexOutOfBoundsException: Index: 1, Size: 0
java.lang.IndexOutOfBoundsException: Index: 1, Size: 0
        at java.util.ArrayList.RangeCheck(ArrayList.java:547)
        at java.util.ArrayList.get(ArrayList.java:322)
        at org.primefaces.component.api.UITree.findTreeNode(UITree.java:112)

hint for others running into this problem: as a temporary workaround for node selection i use a node label span onclick that triggers a prepared RemoteCommand with parameter. thus i can disable node selection and problem is challenged for now.
