How to call HTML dialog's method from java

hieulam — Wed, 04 Dec 2019 04:53:52 -0500

Dear Ivy team I would like to know is there any way to trigger a HTML dialog from java code. Lets me describe the situation: I have a page that contains a method named "run"

In HTML view I have a button to call a method from backing bean "Bean" Now what we need to how to trigger method "run" from the backing bean

We can achieve this only when the method belongs to an Ivy component by using something like this Unfortunately, this way only work for Ivy's component, not for the page. So my question is do we have any way to call HTML dialog's method from java?

Ivy task with start link Ivy is not persisted immediately

Dear Ivy team.

At the moment, we're facing the problem with start link ivy is marked as Persist task on creation come with some additional data what was set in customvarcharfield.

We create a trigger in our ivy's database to listen to any changes in iwa_task table. We saw that whenever a user starts that ivy link. ivy will insert a new record in table iwa_task with a taskid but the value for customvarchar1 is empty, very quickly after that, ivy also performs another update on the same task to update data for customvarchar. After 2 updates in the iwa_task table, we have the correct data with a task that is created come with customvarcharfield.

It works pretty well for single user because the delay time between 2 updates is very short and unnoticeable. But when there are many users are working at the same time, we got the problem. Because each user access the Portal's tasklist at the same time, so they will query the existing tasks in the system. But under some unluckily moment, the task is created (at the first stage without customvarchar) is queried and return to other user's results. Without customvarchar means the task data is not displayed properly.

I just wonder is there any way to make "Persist task on creation" is persisted only once with full of data instead of creating an empty task and update data later?

Thank in advanced.

Migrate Primface Push from Ivy 6.3 to Ivy 7.0.3

Hi all. Currently, we're migrating our projects from Ivy 6.3 to Ivy 7.0.3. One of the problems we're facing is PrimePush doesn't work anymore in Chrome but still works in Internet Explorer and FireFox. Previously this feature works on all browsers
We followed this instruction to implement PrimeFacePush for Ivy 6.3: https://answers.axonivy.com/questions/10/can-i-use-primepush-in-xpert-ivy
Error in Chrome when the page is loaded:
