Saving latest/last user request parameters

Let’s take interface filters, as example - use restoreRequestParams method in org.bgerp.action.base.BaseAction

Saving a value:

// PzdcDoc snippet of: 'org.bgerp.action.MessageAction', lines: 498 - 498

        restoreRequestParams(conSet.getConnection(), form, true, false, "messageTypeAdd");

Restoring a value:

// PzdcDoc snippet of: 'org.bgerp.action.MessageAction', lines: 530 - 537

public ActionForward processMessageUpdate(DynActionForm form, Connection con) throws Exception {
    var type = getType(form.getParamInt("typeId"));

    // preserving message type for choosing in next usage of editor
    if (form.getId() <= 0) {
        form.setParam("messageTypeAdd", String.valueOf(type.getId()));
        restoreRequestParams(con, form, false, true, "messageTypeAdd");
    }

Saving and restoring a value at once:

// PzdcDoc snippet of: 'ru.bgcrm.struts.action.ProcessLinkAction', lines: 48 - 52

// процессы, к которым привязана сущность
public ActionForward linkedProcessList(DynActionForm form, Connection con) throws Exception {
    ProcessLinkDAO processLinkDAO = new ProcessLinkDAO(con, form);

    restoreRequestParams(con, form, true, true, "open");

Feature flag for UI

Option stored in user personalization map. UI dropbox available in user profile settings.

<%-- PzdcDoc snippet of: 'webapps/WEB-INF/jspf/user/profile/default.jsp', lines: 39 - 45 --%>

<c:set var="key" value="iface.buffer.behavior"/>
<ui:combo-single hiddenName="${key}" value="${ctxUser.personalizationMap.get(key, '1')}" widthTextValue="200px">
        <jsp:attribute name="valuesHtml">
                <li value="1">${l.l('Последний объект сверху')}</li>
                <li value="2">${l.l('Сохранять порядок объектов')}</li>
        </jsp:attribute>
</ui:combo-single>

Stored values may be read in JSP pages using in the same ctxUser.personalizationMap way, but also available in JS like for this case.

// PzdcDoc snippet of: 'webapps/js/kernel.shell.js', lines: 458 - 459

if (($$.pers["iface.buffer.openOnLongPress"] || 0) === 1) {
        const debug = $$.debug("buffer");

Depicting element count on a tab

For example, showing associated processes count. Gets saved on the first call. Use ru.bgcrm.model.IfaceState class.

Show on a tab’s header:

<%-- PzdcDoc snippet of: 'webapps/WEB-INF/jspf/user/process/process/process_editor.jsp', lines: 77 - 88 --%>

        <c:if test="${processType.properties.configMap.getSok('1', false, 'show.tab.links.process', 'processShowProcessLinks') eq '1'}">
                <c:set var="ifaceId" value="link_process"/>
                <c:set var="ifaceState" value="${ifaceStateMap[ifaceId]}"/>

                <c:url var="url" value="/user/process/link/process.do">
                        <c:param name="id" value="${process.id}"/>
                        <c:param name="ifaceId" value="${ifaceId}"/>
                        <c:param name="ifaceState" value="${ifaceState.state}"/>
                </c:url>

                $tabs.tabs("add", "${url}", "${l.l('Related Processes')}<span class='iface-state'>${ifaceState.formattedState}</span>");
        </c:if>

Update value in DB:

// PzdcDoc snippet of: 'org.bgerp.action.ProcessLinkProcessAction', lines: 53 - 61

IfaceState currentState = new IfaceState(form);
if (Utils.notBlankString(currentState.getIfaceId())) {
    Pair<Integer, Integer> counts = new ProcessLinkDAO(conSet.getSlaveConnection()).getLinkedProcessesCounts(form.getId());

    IfaceState newState = new IfaceState(Process.OBJECT_TYPE, form.getId(), form,
            String.valueOf(counts.getFirst()),
            String.valueOf(counts.getSecond()));
    new IfaceStateDAO(conSet.getConnection()).compareAndUpdateState(currentState, newState, form);
}

Refresh on a tab’s header:

<%-- PzdcDoc snippet of: 'webapps/WEB-INF/jspf/user/process/process/link/process/default.jsp', lines: 6 - 10 --%>

<script>
        $(function () {
                $$.ui.ifaceStateTabUpdate('${uiid}', '${ifaceState.formattedState}');
        })
</script>

Date and time format

When formatting date and time values in Java or JSP , use the following formats in order to keep unified approach and maintain independence from the current locale:

ymd - year, month, date;
ymdh - year, month, day, hour;
ymdhm - year, month, day, hour, minute;
ymdhms - year, month, day, hour, minute, second.

Java code uses ru.bgcrm.util.TimeUtils class for date formatting, this class also contains format constants.

The same functions may be used in JSP using tu prefix:

<%-- PzdcDoc snippet of: 'webapps/WEB-INF/jspf/user/parameter/edit.jsp', lines: 168 - 168 --%>

<input type="text" name="value" value="${tu.format(data.value, type)}" id="${focusFieldUiid}" ${changeAttrs} onclick="${getCommand}"/>

Configuration Java Beans

In order to speed up parsing and validation, use Java class objects inherited from org.bgerp.app.cfg.Config For example: org.bgerp.model.process.config.IsolationConfig. This configuration supports constructor with a validation flag, which allows to check syntax when saving.

Configuration bin can be also obtained in JSP:

<%-- PzdcDoc snippet of: 'webapps/WEB-INF/jspf/user/plugin/task/task_list.jsp', lines: 4 - 4 --%>

<c:set var="config" value="${ctxSetup.getConfig('ru.bgcrm.plugin.task.Config')}"/>

Pagination

Putting results into JSP and rendering a form:

<%-- PzdcDoc snippet of: 'webapps/WEB-INF/jspf/admin/process/status/list.jsp', lines: 4 - 18 --%>

<html:form action="${form.requestURI}" styleClass="in-mr1">
        <input type="hidden" name="method" value="statusList"/>
        <input type="hidden" name="id" value="-1"/>
        <input type="hidden" name="returnUrl" value="${form.requestUrl}"/>

        <c:url var="url" value="${form.requestURI}">
                <c:param name="method" value="statusGet"/>
                <c:param name="id" value="-1"/>
                <c:param name="returnUrl" value="${form.requestUrl}"/>
        </c:url>

        <ui:button type="add" onclick="$$.ajax.loadContent('${url}', this)"/>

        <ui:page-control/>
</html:form>

Java action:

// PzdcDoc snippet of: 'ru.bgcrm.struts.action.admin.ProcessAction', lines: 52 - 56

    public ActionForward statusList(DynActionForm form, Connection con) throws Exception {
        new StatusDAO(con).searchStatus(new Pageable<>(form));

        return html(con, form, PATH_JSP + "/status/list.jsp");
    }

File upload

JSP page:

<%-- PzdcDoc snippet of: 'webapps/WEB-INF/jspf/admin/license/license.jsp', lines: 9 - 16 --%>

        <form action="${form.requestURI}" method="POST" enctype="multipart/form-data">
                <input type="hidden" name="method" value="upload"/>
                <input type="hidden" name="responseType" value="json"/>
                <input type="file" name="file" style="visibility: hidden; display: none;"/>
                <button type="button" class="btn-grey w100p mt1" onclick="$$.ajax.fileUpload(this.form).done(() => {
                        $$.ajax.loadContent('${form.requestUrl}', this);
                })">${l.l('Загрузить файл лицензии')}</button>
        </form>

Put an attention to the ${form.requestURI} expression, which gets action URL of the current action and prevents duplication of code.

Action:

// PzdcDoc snippet of: 'org.bgerp.action.admin.LicenseAction', lines: 29 - 42

public ActionForward upload(DynActionForm form, ConnectionSet conSet) throws Exception {
    var file = form.getFile();

    byte[] data = IOUtils.toByteArray(file.getInputStream());

    String error = new License(new String(data, StandardCharsets.UTF_8)).getError();
    if (Utils.notBlankString(error))
        throw new BGMessageException(error);

    IOUtils.write(data, new FileOutputStream(License.FILE_NAME));
    AppLicense.init();

    return json(conSet, form);
}

Flex layout, using constants from Java classes (defined in process_search_constants.jsp), print button close to a field:

<%-- PzdcDoc snippet of: 'webapps/WEB-INF/jspf/user/search/search.jsp', lines: 65 - 79 --%>

        </div>
</div>

For some reason a class, containing included constant must not contain config word in package path.
