Xoops 2.5.7.1
firefox 37.0.2
a) module installing
a.1) uninstalled previous version
a.2) cleaned up cache
a.3) installed 1.91 alpha 3 - ok
b) Testing module TDMCreate
b.1) created new module (named: mytestmodule) - ok
b.2) create new table (named: tables1) for this new module - ok
b.3) in parameter list there is 'TextDateSelect'. Please make additionally a 'TextDateTimeSelect'
b.4) changed later number of fields/add new field to this table - ok
b.5) create second table (named: tables2) for this new module - ok
no error, but: in parameter list 'tables1' appears two times
Searching for reason I found:
in admin/fields.php there is at switch 'save' after line 170 (if ($fieldsObj->isNew()) {)
 // Fields Elements Handler 
            $fieldelementObj =& $tdmcreate->getHandler('fieldelements')->create(); 
            $fieldelementObj->setVar( 'fieldelement_mid', $fieldMid ); 
            $fieldelementObj->setVar( 'fieldelement_tid', $fieldTid ); 
            $fieldelementObj->setVar( 'fieldelement_name', 'Table : '.ucfirst($tableName) ); 
            $fieldelementObj->setVar( 'fieldelement_value', 'XoopsFormTables-'.ucfirst($tableName) ); 
            // Insert new field element id for table name 
            if (!$tdmcreate->getHandler('fieldelements')->insert($fieldelementObj) ) { 
                $GLOBALS['xoopsTpl']->assign('error', $fieldelementObj->getHtmlErrors() . ' Field element'); 
            }  
and each time you add a new field you get a new item in table 'tdmcreate_fieldelements' for the same table (indicated by my test item 7)
please delete this and add in admin/tables.php after line 187 ($tableAction = '&field_mid=' . $tableMid . '&field_tid=' . $tableTid . '&field_numb=' . $tableNumbFields . '&field_name=' . $tableFieldname;)
 // Fields Elements Handler 
                $fieldelementObj =& $tdmcreate->getHandler('fieldelements')->create(); 
                $fieldelementObj->setVar( 'fieldelement_mid', $tableMid ); 
                $fieldelementObj->setVar( 'fieldelement_tid', $tableTid ); 
                $fieldelementObj->setVar( 'fieldelement_name', 'Table : '.ucfirst($_POST['table_name']) ); 
                $fieldelementObj->setVar( 'fieldelement_value', 'XoopsFormTables-'.ucfirst($_POST['table_name']) ); 
                // Insert new field element id for table name 
                if (!$tdmcreate->getHandler('fieldelements')->insert($fieldelementObj) ) { 
                    $GLOBALS['xoopsTpl']->assign('error', $fieldelementObj->getHtmlErrors() . ' Field element'); 
                }  
, then you get only a new item in table 'tdmcreate_fieldelements', if you create a new table
b.6) if you delete a table, the item in table 'fieldelements' is not deleted and it will be still shown in parameter list for the fields (and this can only make troubles)
please add in admin/tables at switch 'delete' after 'if ($tdmcreate->getHandler('tables')->delete($tablesObj)) {'
 //delete items in table fieldelements 
                $crit_fieldelements = new CriteriaCompo(); 
                $crit_fieldelements->add(new Criteria('fieldelement_tid', $tableId)); 
                $fieldelements = $tdmcreate->getHandler('fieldelements')->getAll($crit_fieldelements); 
                foreach (array_keys($fieldelements) as $fe) { 
                    $fieldelementsObj =& $tdmcreate->getHandler('fieldelements')->get($fieldelements[$fe]->getVar('fieldelement_id')); 
                    if (!$tdmcreate->getHandler('fieldelements')->delete($fieldelementsObj)) { 
                        echo $fieldelementObj->getHtmlErrors(); 
                    } 
                    unset ($fieldelementsObj); 
                }  
 b.7) after clicking on building module, all is marked es well done
c) testing new module
c.1) installing module - ok
c.2) after installation I went directly to module settings, after click on safe I got error:
Parse error: syntax error, unexpected 'public' (T_PUBLIC) in C:\Homepages\Xampp\htdocs\xoops2571\htdocs\modules\mytestmodule\class\tables1.php on line 173
Searching for error I found:
- in my 'tables1' I have as last field a radio yes/no, named 't1_add_yesno'
- in class/tables1.php after the class MytestmoduleTables1 there is additionally 
 /** 
     * Get Options 
     */ 
    public function getOptions() 
    { 
        $ret = array(); 
        if (1 == $this->getVar('t1_add_yesno')) { 
            array_push($ret, 'add_yesno'); 
        } 
        return $ret; 
    } 
}  
and this causes the error
if I delete this, it works
c.3) adding new item to tables1 - ok
c.4) adding new item to tables2 works, but:
I have in my 'tables2' one field with type 'DhtmlTextArea'. In the form generated by class/tables2.php I get the always the editor defined by 'Preferences/Editor'
That's basically ok, but we have 3 possibilities:
- then we should name the field type e.g. 'Editor defined in module prefs'
- this field should be always 'DhtmlTextArea'
- make field type 'DhtmlTextArea' (which should be then always DhtmlTextArea) plus 'Editor defined in module prefs' 
d) Testing user side of new module:
d.1) on the index pages there are following errors in debug area:
Notice: Undefined variable: sysPathIcon32 in file /modules/mytestmodule/footer.php line 26
Notice: Undefined variable: dirname in file /modules/mytestmodule/footer.php line 28
Notice: Undefined variable: dirname in file /modules/mytestmodule/footer.php line 30
Notice: Undefined variable: dirname in file /modules/mytestmodule/footer.php line 31
d.2) on the index pages there is e.g _MA_MYTESTMODULE_TABLES1, but in the language file is _MA_MYTESTMODULE_TABLE1 defined
now we can change _MA_MYTESTMODULE_TABLES1 or _MA_MYTESTMODULE_TABLE1
IMO we should change to _MA_MYTESTMODULE_TABLES1, otherwise we have later the same problem with _MA_MYTESTMODULE_TABLES1_DESC
in class/files/language/LanguageMain.php line 98 ff should be
 $tableName    = $tables[$i]->getVar('table_name'); 
            $stuTableName = strtoupper($tableName); 
            $ucfTableName = UcFirstAndToLower($tableName); 
            $tableSoleName    = $tables[$i]->getVar('table_solename'); 
            $stuTableSoleName = strtoupper($tableSoleName); 
            $ucfTableSoleName = UcFirstAndToLower($tableSoleName); 
            $ret .= $this->defines->getAboveDefines($ucfTableName); 
            $ret .= $this->defines->getDefine($language, $stuTableName, $ucfTableName); 
            $ret .= $this->defines->getDefine($language, "{$stuTableName}_DESC", "{$ucfTableName} description"); 
            $ret .= $this->defines->getAboveDefines("Caption of {$ucfTableName}");  
 instead of
 $tableSoleName    = $tables[$i]->getVar('table_solename'); 
            $stuTableSoleName = strtoupper($tableSoleName); 
            $ucfTableSoleName = UcFirstAndToLower($tableSoleName); 
            $ret .= $this->defines->getAboveDefines($ucfTableSoleName); 
            $ret .= $this->defines->getDefine($language, $stuTableSoleName, $ucfTableSoleName); 
            $ret .= $this->defines->getDefine($language, "{$stuTableSoleName}_DESC", "{$ucfTableSoleName} description"); 
            $ret .= $this->defines->getAboveDefines("Caption of {$ucfTableSoleName}");  
 d.3) if I want to show my 'tables1' I get errors:
Parse error: syntax error, unexpected ')' in C:\Homepages\Xampp\htdocs\xoops2571\htdocs\modules\mytestmodule\tables1.php on line 54
please check class/files/user/UserPages.php line 137
IMO the line 
 $xoBreadcrumbs[] = {$language}{$stuTableSoleName});  
 can be deleted
d.4) fixed bug d.3), if I want to show once more my 'tables1' I get error:
Notice: Use of undefined constant _MA_MYTESTMODULE_TABLE1 - assumed '_MA_MYTESTMODULE_TABLE1' in file /modules/mytestmodule/tables1.php line 53
Notice: Undefined variable: sysPathIcon32 in file /modules/mytestmodule/footer.php line 26
Notice: Undefined variable: dirname in file /modules/mytestmodule/footer.php line 28
Notice: Undefined variable: dirname in file /modules/mytestmodule/footer.php line 30
Notice: Undefined variable: dirname in file /modules/mytestmodule/footer.php line 31
d.5) in class/files/user/UserPages.php line 136 
 $xoBreadcrumbs[] = array('link' => {$stuModuleDirname}_URL . '/{$tableName}.php', 'title' => {$language}{$stuTableSoleName});  
should be replace by
 $xoBreadcrumbs[] = array('link' => {$stuModuleDirname}_URL . '/{$tableName}.php', 'title' => {$language}{$stuTableName});  
d.6) the content of my tables1 is not shown, reason:
in tables1.php you create an array named 'tables1_list' which is appended to templates/mytestmodule/tables1.tpl, but there I find '<{foreach item=list from=$tables1}>'
therefore in class/files/templates/user/TemplatesUserPages.php line 129 
 <{foreach item=list from=${$tableName}}>;  
 should be replace by 
 <{foreach item=list from=${$tableName}_list}>  
d.7) fixed d.5, but in the list header you find always '_MA_MYTESTMODULE_T1_ID', '_MA_MYTESTMODULE_T1_NAME' and so one
reason:
in tables1.tpl you have _MA_MYTESTMODULE_T1_ID, in language file main.php you have _MA_MYTESTMODULE_TABLE1_ID
Stop testing for the moment
