tree table component with auto expanded nodes

[PN_5076692]

Hello,

for one of my customers I've created a wizard step with some change validation info.

the data is arranged in a flat tree structure which is displayed in the treetable component.

See attached example screenshot.

One requirement is that non "green" checks are auto expanded for the user.

I tried to implement it as described in the customizers guide, but so far no luck.

The TreeTable component uses a custom AbstractConfigurableTableBuilder with an custom ExpansionStateManager

the table config looks like this

JcaTreeConfig treeCfg = (JcaTreeConfig) factory.newTreeConfig();

        treeCfg.setDataSourceMode(DataSourceMode.DISABLED);
        treeCfg.setType(Object.class.getName());
        treeCfg.setTargetObject("origObject");
        treeCfg.setComponentMode(ComponentMode.VIEW);
        treeCfg.setActionModel("tcw tcwValidation table");
        //treeCfg.setMenubarName("tcw tcwValidation table");

        treeCfg.setId(TCW_TCWVALIDATION_TABLE_ID);
        treeCfg.setLabel(WTMessage.getLocalizedMessage(TCW_RESOURCE, "tcw.validationTable.title", (Object[]) null, SessionHelper.getLocale()));

        treeCfg.setNodeColumn(TCW_VAL_COLID_VALTYPE);

        treeCfg.setShowTreeLines(true);
        treeCfg.setExpansionLevel(DescriptorConstants.TableTreeProperties.FULL_EXPAND);

        treeCfg.setFindInTableEnabled(false);
        treeCfg.setFindInTableMode(FindInTableMode.DISABLED);
        treeCfg.setShowCount(true);

        treeCfg.setDisableAction("false");
        treeCfg.setRowBasedObjectHandle(true);

        addColumn(TCW_VAL_COLID_VALTYPE, treeCfg, factory, true, false, false);
        addColumn(TCW_VAL_COLID_CHECKTYPE, treeCfg, factory, true, false, false);
        addColumn(TCW_VAL_COLID_MESSAGE, treeCfg, factory, true, false, false);
        addColumn(TCW_VAL_COLID_RESULTTYPE, treeCfg, factory, true, false, false);
        if (isTCWWizardMode) {
            addColumn(TCW_VAL_COLID_ACTION, treeCfg, factory, true, false, false);
            addColumn(TCW_VAL_COLID_RELATEDOBJ, treeCfg, factory, true, false, false);
        }

the root nodes list is build like this

        List rootNodes = new ArrayList();
        for (TCWValidationCheckType t : topChecks) {
            TCWValidationBean rowBean = new TCWValidationBean(t);
            rowBean.setModelContext(modelContext);
            rowBean.setHasChildren(true);
            rowBean.setDepth(1);
            if ("INFO".equals(t.getCheckResult())) {
                if (!"hideAllGreen".equals(resultFilter)) {
                    addExpandedNode(rowBean);
                    rootNodes.add(rowBean);
                }
            } else if (!"SUCCESS".equals(t.getCheckResult())) {
                // check is not ok, add to auto expand list
                addExpandedNode(rowBean);
                rootNodes.add(rowBean);
            } else {
                if (!"hideAllGreen".equals(resultFilter)) {
                    rootNodes.add(rowBean);
                }
            }
        }
        if (rootNodes.isEmpty()) {
            // add entry "all successfull"
            String x = WTMessage.getLocalizedMessage(TCW_RESOURCE,"tcw.validation.summarymessage.allchecksok", (Object[]) null, SessionHelper.getLocale());
            TCWValidationBean rowBean = new TCWValidationBean(x);
            rootNodes.add(rowBean);
            addExpandedNode(rowBean);
        }

the overriden method isExpandNeeded looks like this

    @Override
    public boolean isExpandNeeded(Object beanObjIn, int level) throws WTException {
        boolean expandNeeded = false;
        if (beanObjIn instanceof TCWValidationBean) {
            TCWValidationBean tcwValBean = (TCWValidationBean) beanObjIn;
            if (this.getExpandedOids() != null && tcwValBean.getOid() != null && this.getExpandedOids().contains(tcwValBean.getOid().toString())) {
                expandNeeded = true;
            }
        } 
        return expandNeeded;
    }

setting the root nodes for expand & setting everything to expand_full seems to have no effect.

there are no errors or hints in the log unfortunately.

manual by the user "expand" works without a problem.

any suggestions maybe? what did I forget/miss? 😉

THANKS!

Hi @PN_5076692 

I've never found a way how to expand the tree automatically by API. 

As you've mentioned  the expand_full really does not work at all. 

I usually add an action expand all for user to the table menu.

Hello @HelesicPetr 

well, that's unfortunate. 😕 

In the meantime I tried different approaches but so far no luck.

It seems that I would need to create some additional JS code and simulate onClick event to expand certain entries.

(Like your proposal)
