Scheduling Gantt Chart - highlighting of modified duties

We strive to implement our Gantt chart behavior as on the actions of the user like drag-and-drop, changes are not immediately committed to the database.

We ask a commit on the transaction to save all changes when the user presses a button 'save'.

However, we would like to highlight modified (for example, the extended duration task) duties in a different color to keep track of all the actions of the user, while the changes are not yet validated.

Commit, all jobs must go back to the default color.

I'm doing it with the TaskbarFormatManager, but can't find a way to use it for this particular requirement.

Can I use a column in my table to map the type of task for the Gantt chart, and how to upgrade this attribute in my VO / Gantt chart when a task is changed?

I managed to solve this problem quite awhile, but I forgot to post the solution.

I have added a transitional attribute to my entity object.

<>

Name = "TaskChanged".

ColumnName = "" $aucun$ ""

SQLType = 'VARCHAR '.

Type = "Java.lang.String"

ColumnType = "" $aucun$ ""

IsQueriable = "false".

IsPersistent = "false" / >

In the entity bean Get accessor method.

public String getTaskChanged() {}

If (this.getEntityState () is EntityImpl.STATUS_MODIFIED)

return "CHANGED";

If ((String) getAttributeInternal (TASKCHANGED) is nothing)

on the other

'CLEAN '; return

}

Add this attribute of the entity object to the original Version. The application of VO is unchanged.

In the Gantt chart in the jspx, I put the Task Type to the attribute TaskChanged.

And the code for TaskbarFormatManager is as usual:

public TaskbarFormatManager getFormatManager() {}

TaskbarFormatManager _manager = new TaskbarFormatManager();

_manager.registerTaskbarFormat ("CHANGE", TaskbarFormat.getInstance ("gold", UISchedulingGantt.GOLD_FORMAT));

_manager.registerTaskbarFormat ('CLEAN', TaskbarFormat.getInstance ("blue", UISchedulingGantt.STEEL_BLUE_FORMAT));

Return _manager;

}

When the validation is called when the click on the "Save" button, the entity is no longer in an altered state, and all the recorded tasks back to the steel blue format.

  • Scheduling Gantt: legend

    Hi all!

    ADF/JDev version: 12.1.3

    On the Gantt chart scheduling, we have included a legend.

    In the tags and keys, we have defined what should be displayed in the legend.

    The documentation says the following:

    Labels - labels for keys of data specified in the attribute keys object. This attribute is always used in conjunction with keys, and the number of keys must match the number of labels.

    Key - the key of data object used to retrieve values for fill in the legend. These values are essentially properties associated with the task object returned by the attribute GanttModelThis is always used in conjunction with the labels, and the number of keys must match the number of labels.

    If the key is null, the legend is printed in red letters missed.

    Example:

    Description: a description

    Reference: failed

    Can we influence somehow the missed Word?

    Kind regards

    Probably nothing. I get the same error with a similar request, but after selecting the option Save query without validation when you apply the changes, the graphic is displayed correctly. Potentially, a bug in the validation of the application.

    I'd actually using the region of Gantt plugin found in the application of P-Track packed instead, which is a component of HTML5 more modern which is a better choice for use in the universal theme.

    Hi Dejan,

    You had the largest part of the correct configuration. I finished the example.

    1 / the LINK column added to the query of the series.

    2 / in the series, I specified the link attributes. The URL used is: javascript:setURLForModal('#LINK#').

    3 / the raised event was a typo in it. Correct it.

    4 / the dynamic action is triggered on the issue, not on the region. The attribute must be data-url and not data_url

    The example works now. Œuvres pretty cool and it's almost all defined by their Summit.

    Thank you

    Erick

    Erick,

    What makes you decide to use a chart of the resource instead of a task of projects, so what you are viewing is just a chart of the project? No resource is indicated on the data grid, but rather task names. Not not it doesn't, but it's confusing that shouldn't be there. It complicates the xml code required when it should not.

    Aside from that, you can do what you want, but you need to change the custom XML and generate xml data yourself.

    See page 2 in your application: https://apex.oracle.com/pls/apex/f?p=16559:2

    -generate xml processes

    -region with a few hidden items

    -custom xml to include items hidden in the correct places

    -remove the series just to indicate that no data is retrieved in a way

    In short:

    -generate xml data to generate a style for every single transferee. I generate a name for each "style" | assignee_id, which makes it easy to reference in the task. I added a function to generate a custom hex color too, just for the joy?

    -generating resources

    -generate periods and assign the style accordign to the assignee

  • Can we create Gantt chart using BI Publisher plug-in

    Hi Evereyone,.

    I'm working on a report that requires the Gantt chart to be published by unify. I use the BI Publisher MS Word and Excel plugin.

    Has anyone tried this before. It will be useful if you can share the steps or any other site which deals with creation of Gantt chart.

    Thank you

    It is possible. See this site for a starting point: https://blogs.oracle.com/xmlpublisher/entry/getting_gantty

    Basically, you create a table where each row represents an activity from your calendar sheet. You will need a space of great column for the Gantt chart and add a few MS Word forms (rectangles).

    If you play with and you can move the bar and size correctly. Download the appropriate shifts and durations in your data SQL view.

    This is the easiest part. The hardest part is to show the dates (weeks/months/years) at the top of your table with spacing on the right... It is actually easier to just the dates of beginning and end of each line.

    -It should be noted that showing the relationships between activities (ie. the lines connecting the bars) cannot be done in BI Publisher. If it is a requirement, I suggest that investigate you other approaches. You can list predecessor and successor activity in the form of column ID in your table instead.

    Hope that helps,

    The f

  • Grid in Gantt chart

    Hello

    It is a problem with a Gantt chart that is part of an Apex application I support. It uses the format to_timestamp (DD-MON-RRRR hh: mi) to retrieve the data and display in the Gantt chart. The only problem is that since I use the format HH and AM not HH24 all the time is displayed in 12-hour format the component "hour" of the x_axis chart seems to be assuming that time is always. Is there anyway to fix this, or simply change the x_axis to show say 05:00 instead of 17:00?

    Thank you

    His assuming that all times are AM because you forgot to tell the to_timestamp() function if time is or h... so, it must assume that it is always AM.

    Your date/time data must be stored in a DATE data type.

    Use the CAST (columname AS TIMESTAMP) operator if it is already a DATE instead of using to_timestamp (to_char ())

  • Order of the Gantt chart

    Hello

    I created a Gantt chart and discovered a problem. Jobs don't always appear in chronological order.

    I tried to order the query by date, but then the tasks don't always show next (or in the same order) on the bars to the right of the plan.

    Is anyway I can order the tasks without losing the alignment with the diagram of the individual task bar?

    Thanks in advance.

    Hello

    You have not specified what type of Gantt chart, you use: it is a project gantt chart or resource? In addition, you are dealing with hierarchical data?

    Looks like you might be dealing with hierarchical data and the order in which the data are generated is cause your problem and culminating in the timeline entries being out of alignment with the datagrid control.  So, without seeing the application in use, my suggestion would be to update the query to generate a hierarchical representation of your data via an START WITH... CONNECT BY question, using a syntax similar to the following:

    Select the link,
    TaskName,
    ID,
    parent_id,
    start_date,
    End_date,
    status
    tasks _table
    Start by parent_id is null
    connect by parent_id = prior id
    siblings arrested by start_date

    If the query is retrieving the list of tasks and then hierarchically by listing the based on parent-child association which was held in the PARENT_ID of the table column.  The end result means that each parent task is listed with their tasks associated with children and sorted by START_DATE.

    If this isn't answering your query, please update this thread with more information about your test scenario.  Even better - if you could create a unit test on apex.oracle.com and post a link to the unit test and the syntax of the query you are using, it would be very useful.

    Kind regards
