How to use dojo.query to filter out few unwanted elements

Ever had scenario where you use a dojo.query to get the list of elements with some specific class but then realized you need to ignore few more elements from the result but cannot as those elements also have the same class defined.
No problem you can modify your query string to add the not function and pass in the new unique class which only these controls have. Not able to find any unique class, no issues, you can manually assign one custom class and use it in the query.
I encountered this requirement while working in IBM BPM Coaches but this is not specific to BPM instead it's a pattern for dojo query.
So here is an example of filtering the controls using the class names in the dojo.query

dojo.query(".CPP") gives me the list of all the interactive controls in the page. But I don't want the button controls and my button control has another class as "Button" to my modified query will be

dojo.query(".CPP:not(.Button)")
This query will list all the elements with CPP class and exlude those which has CPP & Button class together.

How to get URL of web file in IBM BPM

In IBM BPM, sometimes we need the URL of the web files added to the process app. Below is the script that can be used to get the actual URL of the web file dynamically helping to avoid the static hardcoding. com_ibm_bpm_coach.getManagedAssetUrl("file.png",com_ibm_bpm_coach.assetType_WEB Hope this will be helpful. Thank you for stopping by. Please leave comment and share if this helps you. Cheers!!

Simple timer implementation in IBM BPM service

In IBM BPM we can use the Timer events in the BPDs to introduce the waiting period but we don't have any direct implementation of the timer in the service flows (or the server-side scripts). In this post, I'll explain a simple way to use the existing Java class in the script to simulate the time delays in the server-side logic. Below image shows the implementation of it. In the above example, I have used the java.lang.Thread.sleep() method to add the desired delay. The best part of this implementation is we don't need to import any additional package or classes the time is accurate to the milliseconds and not random and different when we try to use the counter and for/while loop Below is the script for reference var waitTime = function(milliseconds) { log.info("Wait time for " milliseconds" + milliseconds start"); java.lang.Thread.sleep(milliseconds); log.info("wait time over"); } waitTime(2000); That's all i...

How to pass parameter to function while calling it in spark controls

This is extension to the article of Creating Custom Functions in Spark UI Toolkit. It don't have option to explain how to define the function with real input parameter and invoke it with data. To understand how to Create Custom Function in Spark, please refer this link. Here I'll explain how to define the function with real input parameter (not the control input) and how to invoke it with the data. It's the normal way of writing any parameterized function in custom HTML (Advanced control) in IBM BPM, like openLink(control, val) {//code here;}. Screenshot below. In this you can see I'm using val variable to get the input and deciding the link to open based on it's value. The suggested way to call the function in spark on any control event is like @openLink() as shown below. But this will not pass any value. Interestingly as per the explanation in the Spack help, it pass the control reference in the function. and you can't try the combinations of passing the e...
