Code Snippets in AX 2012 (Some tips and tricks)

Add below method in XppSource class

******************************

Source findMethod(TableName _tableName, boolean _useReplacementKey = false)
{
    DictTable dictTable = new DictTable(tableName2id(_tableName));
    DictIndex dictIndex = new DictIndex(tableName2id(_tableName),
        (_useReplacementKey && dictTable.replacementKey() != 0) ? dictTable.replacementKey() : dictTable.primaryIndex());
    DictField dictField;
    int fieldIndex;

    if (dictIndex == null)
        throw error(strFmt("Couldn't find primary index for table %1", _tableName));

    // method signature returning the table
    source += strFmt('public static %1 find(', _tableName);

    // add the primary key fields as the parameters to the find method
    for (fieldIndex=1; fieldIndex<=dictIndex.numberOfFields(); fieldIndex++)
    {
        dictField = new DictField(dictTable.id(), dictIndex.field(fieldIndex));
        source += strFmt('%1 _%2, ', extendedTypeId2name(dictField.typeId()), dictField.name());
    }
    source += strFmt('boolean _update = false)\n');

    indentLevel = 0;
    this.beginBlock();

    // Declare the table
    source += this.indent() + strFmt('%1 %1;\n', _tableName);
    source += '\n';

    // Set update yes/no
    source += this.indent() + strFmt('%1.selectForUpdate(_update);\n', _tableName);

    // select firstonly
    source += this.indent() + strFmt('select firstOnly %1 where', _tableName);
    // add the primary key fields in the where clause
    for (fieldIndex=1; fieldIndex<=dictIndex.numberOfFields(); fieldIndex++)
    {
        dictField = new DictField(dictTable.id(), dictIndex.field(fieldIndex));
        source += '\n';
        source += this.indent() + strFmt('    %1%2.%3 == _%3', ((fieldIndex>1) ? '&& ' : ''), _tableName, dictField.name());
    }
    source += ';\n';

    source += '\n';

    // return the buffer
    source += this.indent() + strFmt('return %1;\n', _tableName);

    this.endBlock();

    return source;
}

Add One method in Editor Script Class

public void template_method_find(Editor editor)
{
    xppSource       xppSource = new xppSource();
    Source          template;
    str             path = editor.path();
    TreeNode        treeNode = path ? TreeNode::findNode(path) : null;
    TableName       tableName;
    #TreeNodeSysNodeType

    if (treeNode)
    {
        treeNode = treeNode.AOTparent();
        if (treeNode && treeNode.treeNodeType().id() == #NT_MEMBERFUNCLIST)
        {
            treeNode = treeNode.AOTparent();
            if (treeNode && treeNode.treeNodeType().id() == #NT_DBTABLE)
            {
                tableName = treeNode.treeNodeName();
            }
        }
    }

    if (!tableName)
    {
        warning("Find method applies to tables only");
        return;
    }

    template = xppSource.findMethod(tableName);

    editor.insertLines(template);
}
**********************************************************************************
Now, just clear all the lines and type Find in any table method then find method  will automatically create.
