After updating I have checked SVY-359. Webclient Tab order not working - Rich client OK

Still does not work.

Please reopen then with some way to reproduce the issue. We did some fixes for 6.0.5 in tab sequences and thought it would be the same issue. But without a sample is hard to really say what happens there.

SVY-1306 works perfect! Thanks Jan and all contributors ! :)
SVY-1368 Issue still occurs. Note that this only occurs when using the global variable in a relation.

Btw: use the latest signtester of servoyforge if you want to resign everything with your own certificate!!

You have to import again the solution in application server in order for the fix to become effective. Sorry, we forgot to add this comment on case. Does it still happen after reimport?

Hi Servoy,

Before, for arrays annotated with a specific type, we could use the following without warnings:

Note: someCustomType is defined as

/**
* @constructor
*/
function someCustomType()
{
    this.someProperty = 0;
    ...
}

ln 1:   /** @type {Array<someCustomType>} */
ln 2:   var _arr = [];
          ...
ln 3:   for (var _indx = 0; _indx < _arr.length; _indx++)
ln 4:   {
ln 5:       var _item = _arr[_indx];
ln 6:       someMethod(_item.someProperty);
ln 7:   }

In 6.0.5, Servoy displays a warning on line 6 about “someProperty” not being defined - in other words, it does not recognize that the array elements are of the specified type. Is this a regression bug or has the behavior been changed? Do we need now to explicitly type the array elements in order for Servoy to recognize them correctly?

Hi Servoy,

In 6.0.5, the web client generates duplicate tabindex values for elements which at design time are in separate forms.
For example, consider the following:

FormA

  • button_A1 [tabindex=1]
  • button_A2 [tabindex=2]
  • button_A3 [tabindex=3]

FormB

  • button_B1 [tabindex=1]
  • button_B2 [tabindex=2]
  • button_B3 [tabindex=3]
  • tabPanel (contains FormA) [tabindex=4]

At runtime, when FormB is displayed in the web client, there are 6 buttons on the screen but they contain duplicate tabindexes:

  • button_B1 [tabindex=1]
  • button_B2 [tabindex=2]
  • button_B3 [tabindex=3]
  • button_A1 [tabindex=1]
  • button_A2 [tabindex=2]
  • button_A3 [tabindex=3]

So tabbing through them jumps like: button_B1->button_A1->button_B2->button_A2->button_B3->button_A3

This clearly is not the intended result, it should have been button_B1->button_B2->button_B3->button_A1->button_A2->button_A3

It appears that the web client does not take into consideration the fact that FormA is placed in FormB in a panel with tabindex4. The HTML for the buttons should have been generated so that the tabindexes are as follows:

  • button_B1 [tabindex=1]
  • button_B2 [tabindex=2]
  • button_B3 [tabindex=3]
  • button_A1 [tabindex=4] ← this should start with the tabPanel index where the “embedded” form is placed
  • button_A2 [tabindex=5]
  • button_A3 [tabindex=6]

In contrast, the Smart Client does work as expected.

Is this a bug or a change in behavior of the Web Client? If this is an intended behavior, how can we control the tab order of the resulting UI elements on “composite forms” (forms, which contain other forms, which contain other forms, etc.)

This looks like a bug, please open a case for it.

In 6.0.5 we are getting a lot of invalid warnings which were handled correctly in 6.0.4 - is this a known issue which will be resolved in the next release or a change in behavior which requires that we change our code to avoid the warnings?

A few examples:

  • when overriding a method, the result of the call to _super.overrideMethodName() is not recognized even though the base method is correctly annotated with a specific return type;
  • array items are not recognized as being of specific type even though the array itself is correctly annotated as /** @type Array/ or /** @type Array<{promName: String, propValue: Number}>/ (see my previous post in this thread)

Can you copy/paste the warnings? Warnings don’t go away if you do a clean build? (Project → Clean…)

12

lvostinar:
Warnings don’t go away if you do a clean build? (Project → Clean…)

No, the warnings are persistent even after a clean build and can be reproduced in a new workspace.

here are some of them:

In a base form, a method is defined as:

/**
 * This method is used to retrieve the standard, read-only fields as defined by the business logic
 * Descendant forms should overwrite it to provide specific implementation
 * 
 * @param {JSRecord} _record - the record for which the read-only fields apply (may be null)
 * @return {Array<String>} an array containing the names of fields which should not be editable by the user or null if there are no read-only fields
 * 
 * @properties={typeid:24,uuid:"7e13b54d-735b-4ff8-aed4-11ff05d8061a"}
 */
function getSystemReadOnlyFieldNames(_record)
{
    return ['rowid', 'created_dt', 'created_by', 'lastmodified_dt', 'lastmodified_by'];    
}

In a form, which extends the base form, the method getSystemReadOnlyFieldName is overridden like this:

/**
 *
 * @param {JSRecord} _record - the record for which the read-only fields apply (may be null)
 * @return {Array<String>} an array containing the names of fields which should not be editable by the user or null if there are no read-only fields
 *
 * @properties={typeid:24,uuid:"409CCD44-40EA-4250-95EF-82650D125CD5"}
 */
function getSystemReadOnlyFieldNames(_record)
{
    var _readOnlyFields = _super.getSystemReadOnlyFieldNames(_record);

    if (...)
    {
        _readOnlyFields.push('r_ac_distribution');
        _readOnlyFields.push('allow_alt_curr_only');
        _readOnlyFields.push('allow_foreign_curr_only');
    }

    return _readOnlyFields;
}

In this case, Servoy does not recognize that _readOnlyFields local variable is an array and generates the warning “The function push() is undefined in this script” for every call to _readOnlyFields.push(…) This was working correctly in 6.0.4. In previous post https://www.servoy.com/forum/viewtopic.php?f=16&t=17657&p=95573#p95401 I showed an example of the issue with array items (not sure why the post is listed under rossent12344312).

I’m trying to update our test server from 6.0.2 to 6.0.5, but I get the following error:

Any ideas why this doesn’t work?

Additional info: running the update multiple times it does seem to continue with the update, but I’m not able to start the service.

Strange, not heard/seen before.
Is wicket.jar missing in lib dir?

18

No, wicket.jar is in the dir and it is modified/updated today.

19

Assuming you did not move the servoy install dir and not manually edit the wrapper.conf, try with a wrapper.conf from alike install.
If that does not work, you have only reinstall option left.

Again not heard from anyone having any problem with/while updating.
